+System Architecture
+===================
+
+
+This page presents the current technical Architecture of the Watcher system.
+
+.. _architecture_overview:
+
+Overview
+========
+
+Below you will find a diagram, showing the main components of Watcher:
+
+.. image:: ./images/architecture.svg
+   :width: 100%
+
+
+.. _components_definition:
+
+Components
+==========
+
+.. _amqp_bus_definition:
+
+AMQP Bus
+--------
+
+The AMQP message bus handles internal asynchronous communications between the
+different Watcher components.
+
+.. _cluster_history_db_definition:
+
+Cluster History Database
+------------------------
+
+This component stores the data related to the
+:ref:`Cluster History <cluster_history_definition>`.
+
+It can potentially rely on any appropriate storage system (InfluxDB, OpenTSDB,
+MongoDB,...) but will probably be more performant when using
+`Time Series Databases <https://en.wikipedia.org/wiki/Time_series_database>`_
+which are optimized for handling time series data, which are arrays of numbers
+indexed by time (a datetime or a datetime range).
+
+.. _cluster_model_db_definition:
+
+Cluster Model Database
+------------------------
+
+This component stores the data related to the
+:ref:`Cluster Data Model <cluster_data_model_definition>`.
+
+.. _archi_watcher_api_definition:
+
+Watcher API
+-----------
+
+This component implements the REST API provided by the Watcher system to the
+external world.
+
+It enables the :ref:`Administrator <administrator_definition>` of a
+:ref:`Cluster <cluster_definition>` to control and monitor the Watcher system
+via any interaction mechanism connected to this API:
+
+-   :ref:`CLI <archi_watcher_cli_definition>`
+-   Horizon plugin
+-   Python SDK
+
+You can also read the detailed description of `Watcher API`_.
+
+.. _archi_watcher_applier_definition:
+
+Watcher Applier
+---------------
+
+This component is in charge of executing the
+:ref:`Action Plan <action_plan_definition>` built by the
+:ref:`Watcher Decision Engine <watcher_decision_engine_definition>`.
+
+It connects to the :ref:`message bus <amqp_bus_definition>` and launches the
+:ref:`Action Plan <action_plan_definition>` whenever a triggering message is
+received on a dedicated AMQP queue.
+
+The triggering message contains the Action Plan UUID.
+
+It then gets the detailed information about the
+:ref:`Action Plan <action_plan_definition>` from the
+:ref:`Watcher Database <watcher_database_definition>` which contains the list
+of :ref:`Actions <action_definition>` to launch.
+
+It then loops on each :ref:`Action <action_definition>`, gets the associated
+class and calls the execute() method of this class.
+Most of the time, this method will first request a token to the Keystone API
+and if it is allowed, sends a request to the REST API of the OpenStack service
+which handles this kind of :ref:`atomic Action <action_definition>`.
+
+Note that as soon as :ref:`Watcher Applier <watcher_applier_definition>` starts
+handling a given :ref:`Action <action_definition>` from the list, a
+notification message is sent on the :ref:`message bus <amqp_bus_definition>`
+indicating that the state of the action has changed to **ONGOING**.
+
+If the :ref:`Action <action_definition>` is successful,
+the :ref:`Watcher Applier <watcher_applier_definition>` sends a notification
+message on :ref:`the bus <amqp_bus_definition>` informing the other components
+of this.
+
+
+If the :ref:`Action <action_definition>` fails, the
+:ref:`Watcher Applier <watcher_applier_definition>` tries to rollback to the
+previous state of the :ref:`Managed resource <managed_resource_definition>`
+(i.e. before the command was sent to the underlying OpenStack service).
+
+.. _archi_watcher_cli_definition:
+
+Watcher CLI
+-----------
+
+The watcher command-line interface (CLI) can be used to interact with the
+Watcher system in order to control it or to know its current status.
+
+Please, read `the detailed documentation about Watcher CLI
+<https://factory.b-com.com/www/watcher/doc/python-watcherclient/>`_.
+
+.. _archi_watcher_dashboard_definition:
+
+Watcher Dashboard
+-----------------
+
+The Watcher Dashboard can be used to interact with the Watcher system through
+Horizon in order to control it or to know its current status.
+
+Please, read `the detailed documentation about Watcher Dashboard
+<https://factory.b-com.com/www/watcher/doc/watcher-dashboard/>`_.
+
+.. _archi_watcher_database_definition:
+
+Watcher Database
+----------------
+
+This database stores all the Watcher domain objects which can be requested
+by the :ref:`Watcher API <archi_watcher_api_definition>` or the
+:ref:`Watcher CLI <archi_watcher_cli_definition>`:
+
+-  :ref:`Goals <goal_definition>`
+-  :ref:`Strategies <strategy_definition>`
+-  :ref:`Audit templates <audit_template_definition>`
+-  :ref:`Audits <audit_definition>`
+-  :ref:`Action plans <action_plan_definition>`
+-  :ref:`Efficacy indicators <efficacy_indicator_definition>` via the Action
+   Plan API.
+-  :ref:`Actions <action_definition>`
+
+The Watcher domain being here "*optimization of some resources provided by an
+OpenStack system*".
+
+.. _archi_watcher_decision_engine_definition:
+
+Watcher Decision Engine
+-----------------------
+
+This component is responsible for computing a set of potential optimization
+:ref:`Actions <action_definition>` in order to fulfill
+the :ref:`Goal <goal_definition>` of an :ref:`Audit <audit_definition>`.
+
+It first reads the parameters of the :ref:`Audit <audit_definition>` from the
+associated :ref:`Audit Template <audit_template_definition>` and knows the
+:ref:`Goal <goal_definition>` to achieve.
+
+It then selects the most appropriate :ref:`Strategy <strategy_definition>`
+depending on how Watcher was configured for this :ref:`Goal <goal_definition>`.
+
+The :ref:`Strategy <strategy_definition>` is then dynamically loaded (via
+`stevedore <https://github.com/openstack/stevedore/>`_). The
+:ref:`Watcher Decision Engine <watcher_decision_engine_definition>` calls the
+**execute()** method of the :ref:`Strategy <strategy_definition>` class which
+generates a solution composed of a set of :ref:`Actions <action_definition>`.
+
+These :ref:`Actions <action_definition>` are scheduled in time by the
+:ref:`Watcher Planner <watcher_planner_definition>` (i.e., it generates an
+:ref:`Action Plan <action_plan_definition>`).
+
+In order to compute the potential :ref:`Solution <solution_definition>` for the
+Audit, the :ref:`Strategy <strategy_definition>` relies on two sets of data:
+
+-   the current state of the
+    :ref:`Managed resources <managed_resource_definition>`
+    (e.g., the data stored in the Nova database)
+-   the data stored in the

+
+Sequence diagrams
+=================
+
+The following paragraph shows the messages exchanged between the different
+components of Watcher for the most often used scenarios.
+
+.. _sequence_diagrams_create_audit_template:
+
+Create a new Audit Template
+---------------------------
+
+The :ref:`Administrator <administrator_definition>` first creates an
+:ref:`Audit template <audit_template_definition>` providing at least the
+following parameters:
+
+-   A name
+-   A goal to achieve
+-   An optional strategy
+
+.. image:: ./images/sequence_create_audit_template.png
+   :width: 100%
+
+The `Watcher API`_  makes sure that both the specified goal (mandatory) and
+its associated strategy (optional) are registered inside the :ref:`Watcher
+Database <watcher_database_definition>` before storing a new audit template in
+the :ref:`Watcher Database <watcher_database_definition>`.
+
+.. _sequence_diagrams_create_and_launch_audit:
+
+Create and launch a new Audit
+-----------------------------
+
+The :ref:`Administrator <administrator_definition>` can then launch a new
+:ref:`Audit <audit_definition>` by providing at least the unique UUID of the
+previously created :ref:`Audit template <audit_template_definition>`:
+
+.. image:: ./images/sequence_create_and_launch_audit.png
+   :width: 100%
+
+The :ref:`Administrator <administrator_definition>` also can specify type of
+Audit and interval (in case of CONTINUOUS type). There is two types of Audit:
+ONESHOT and CONTINUOUS. Oneshot Audit is launched once and if it succeeded
+executed new action plan list will be provided. Continuous Audit creates
+action plans with specified interval (in seconds); if action plan
+has been created, all previous action plans get CANCELLED state.
+
+A message is sent on the :ref:`AMQP bus <amqp_bus_definition>` which triggers
+the Audit in the
+:ref:`Watcher Decision Engine <watcher_decision_engine_definition>`:
+
+.. image:: ./images/sequence_trigger_audit_in_decision_engine.png
+   :width: 100%
+
+The :ref:`Watcher Decision Engine <watcher_decision_engine_definition>` reads
+the Audit parameters from the
+:ref:`Watcher Database <watcher_database_definition>`. It instantiates the
+appropriate :ref:`strategy <strategy_definition>` (using entry points)
+given both the :ref:`goal <goal_definition>` and the strategy associated to the
+parent :ref:`audit template <audit_template_definition>` of the :ref:`Audit
+<audit_definition>`. If no strategy is associated to the audit template, the
+strategy is dynamically selected by the Decision Engine.
+
+The :ref:`Watcher Decision Engine <watcher_decision_engine_definition>` also
+builds the :ref:`Cluster Data Model <cluster_data_model_definition>`. This
+data model is needed by the :ref:`Strategy <strategy_definition>` to know the
+current state and topology of the audited
+:ref:`Openstack cluster <cluster_definition>`.
+
+The :ref:`Watcher Decision Engine <watcher_decision_engine_definition>` calls
+the **execute()** method of the instantiated
+:ref:`Strategy <strategy_definition>` and provides the data model as an input
+parameter. This method computes a :ref:`Solution <strategy_definition>` to
+achieve the goal and returns it to the
+:ref:`Decision Engine <watcher_decision_engine_definition>`. At this point,
+actions are not scheduled yet.
+
+The :ref:`Watcher Decision Engine <watcher_decision_engine_definition>`
+dynamically loads the :ref:`Watcher Planner <watcher_planner_definition>`
+implementation which is configured in Watcher (via entry points) and calls the
+**schedule()** method of this class with the solution as an input parameter.
+This method finds an appropriate scheduling of
+:ref:`Actions <action_definition>` taking into account some scheduling rules
+(such as priorities between actions).
+It generates a new :ref:`Action Plan <action_plan_definition>` with status
+**RECOMMENDED** and saves it into the:ref:`Watcher Database
+<watcher_database_definition>`. The saved action plan is now a scheduled flow
+of actions to which a global efficacy is associated alongside a number of
+:ref:`Efficacy Indicators <efficacy_indicator_definition>` as specified by the
+related :ref:`goal <goal_definition>`.
+
+If every step executed successfully, the
+:ref:`Watcher Decision Engine <watcher_decision_engine_definition>` updates
+the current status of the Audit to **SUCCEEDED** in the
+:ref:`Watcher Database <watcher_database_definition>` and sends a notification
+on the bus to inform other components that the :ref:`Audit <audit_definition>`
+was successful.
+
+This internal workflow the Decision Engine follows to conduct an audit can be
+seen in the sequence diagram here below:
+
+.. image:: ./images/sequence_from_audit_execution_to_actionplan_creation.png
+   :width: 100%
+
+.. _sequence_diagrams_launch_action_plan:
+
+Launch Action Plan
+------------------
+
+The :ref:`Administrator <administrator_definition>` can then launch the
+recommended :ref:`Action Plan <action_plan_definition>`:
+
+.. image:: ./images/sequence_launch_action_plan.png
+   :width: 100%
+
+A message is sent on the :ref:`AMQP bus <amqp_bus_definition>` which triggers
+the :ref:`Action Plan <action_plan_definition>` in the
+:ref:`Watcher Applier <watcher_applier_definition>`:
+
+.. image:: ./images/sequence_launch_action_plan_in_applier.png
+   :width: 100%
+
+The :ref:`Watcher Applier <watcher_applier_definition>` will get the
+description of the flow of :ref:`Actions <action_definition>` from the
+:ref:`Watcher Database <watcher_database_definition>` and for each
+:ref:`Action <action_definition>` it will instantiate a corresponding
+:ref:`Action <action_definition>` handler python class.
+
+The :ref:`Watcher Applier <watcher_applier_definition>` will then call the
+following methods of the :ref:`Action <action_definition>` handler:
+
+-   **validate_parameters()**: this method will make sure that all the
+    provided input parameters are valid:
+
+    -   If all parameters are valid, the Watcher Applier moves on to the next
+        step.
+    -   If it is not, an error is raised and the action is not executed. A
+        notification is sent on the bus informing other components of the
+        failure.
+
+-   **preconditions()**: this method will make sure that all conditions are met
+    before executing the action (for example, it makes sure that an instance
+    still exists before trying to migrate it).
+-   **execute()**: this method is what triggers real commands on other
+    OpenStack services (such as Nova, ...) in order to change target resource
+    state. If the action is successfully executed, a notification message is
+    sent on the bus indicating that the new state of the action is
+    **SUCCEEDED**.
+
+If every action of the action flow has been executed successfully, a
+notification is sent on the bus to indicate that the whole
+:ref:`Action Plan <action_plan_definition>` has **SUCCEEDED**.

+======================
+
+.. _audit_state_machine:
+
+Audit State Machine
+-------------------
+
+An :ref:`Audit <audit_definition>` has a life-cycle and its current state may
+be one of the following:
+
+-  **PENDING** : a request for an :ref:`Audit <audit_definition>` has been
+   submitted (either manually by the
+   :ref:`Administrator <administrator_definition>` or automatically via some
+   event handling mechanism) and is in the queue for being processed by the
+   :ref:`Watcher Decision Engine <watcher_decision_engine_definition>`
+-  **ONGOING** : the :ref:`Audit <audit_definition>` is currently being
+   processed by the
+   :ref:`Watcher Decision Engine <watcher_decision_engine_definition>`
+-  **SUCCEEDED** : the :ref:`Audit <audit_definition>` has been executed
+   successfully and at least one solution was found
+-  **FAILED** : an error occured while executing the
+   :ref:`Audit <audit_definition>`
+-  **DELETED** : the :ref:`Audit <audit_definition>` is still stored in the
+   :ref:`Watcher database <watcher_database_definition>` but is not returned
+   any more through the Watcher APIs.
+-  **CANCELLED** : the :ref:`Audit <audit_definition>` was in **PENDING** or
+   **ONGOING** state and was cancelled by the
+   :ref:`Administrator <administrator_definition>`

+-  **ONGOING** : the :ref:`Action Plan <action_plan_definition>` is currently
+   being processed by the :ref:`Watcher Applier <watcher_applier_definition>`
+-  **SUCCEEDED** : the :ref:`Action Plan <action_plan_definition>` has been

+Guru Meditation Reports
+=======================
+
+Watcher contains a mechanism whereby developers and system administrators can
+generate a report about the state of a running Watcher service. This report
+is called a *Guru Meditation Report* (*GMR* for short).
+
+Generating a GMR
+================
+
+A *GMR* can be generated by sending the *USR2* signal to any Watcher process
+with support (see below).  The *GMR* will then be outputted as standard error
+for that particular process.
+
+For example, suppose that ``watcher-api`` has process id ``8675``, and was run
+with ``2>/var/log/watcher/watcher-api-err.log``.  Then, ``kill -USR2 8675``
+will trigger the Guru Meditation report to be printed to
+``/var/log/watcher/watcher-api-err.log``.
+
+Structure of a GMR
+==================
+
+The *GMR* is designed to be extensible; any particular service may add its
+own sections.  However, the base *GMR* consists of several sections:
+
+Package
+  Shows information about the package to which this process belongs, including
+  version informations.
+
+Threads
+  Shows stack traces and thread ids for each of the threads within this
+  process.
+
+Green Threads
+  Shows stack traces for each of the green threads within this process (green
+  threads don't have thread ids).
+
+Configuration
+  Lists all the configuration options currently accessible via the CONF object
+  for the current process.
+
+Plugins
+  Lists all the plugins currently accessible by the Watcher service.

+Policies
+========
+
+Watcher's public API calls may be restricted to certain sets of users using a
+policy configuration file. This document explains exactly how policies are
+configured and what they apply to.
+
+A policy is composed of a set of rules that are used in determining if a
+particular action may be performed by the authorized tenant.
+
+Constructing a Policy Configuration File
+----------------------------------------
+
+A policy configuration file is a simply JSON object that contain sets of
+rules. Each top-level key is the name of a rule. Each rule
+is a string that describes an action that may be performed in the Watcher API.
+
+The actions that may have a rule enforced on them are:
+
+* ``strategy:get_all``, ``strategy:detail`` - List available strategies
+
+  * ``GET /v1/strategies``
+  * ``GET /v1/strategies/detail``

+=============================================
+Set up a development environment via DevStack
+=============================================
+
+Watcher is currently able to optimize compute resources - specifically Nova
+compute hosts - via operations such as live migrations. In order for you to
+fully be able to exercise what Watcher can do, it is necessary to have a
+multinode environment to use.
+
+You can set up the Watcher services quickly and easily using a Watcher
+DevStack plugin. See `PluginModelDocs`_ for information on DevStack's plugin
+model. To enable the Watcher plugin with DevStack, add the following to the
+`[[local|localrc]]` section of your controller's `local.conf` to enable the
+Watcher plugin::
+
+    enable_plugin watcher git://git.openstack.org/openstack/watcher
+
+For more detailed instructions, see `Detailed DevStack Instructions`_. Check
+out the `DevStack documentation`_ for more information regarding DevStack.
+
+.. _PluginModelDocs: http://docs.openstack.org/developer/devstack/plugins.html
+.. _DevStack documentation: http://docs.openstack.org/developer/devstack/
+
+Detailed DevStack Instructions
+==============================
+
+#. Obtain N (where N >= 1) servers (virtual machines preferred for DevStack).
+   One of these servers will be the controller node while the others will be
+   compute nodes. N is preferably >= 3 so that you have at least 2 compute
+   nodes, but in order to stand up the Watcher services only 1 server is
+   needed (i.e., no computes are needed if you want to just experiment with
+   the Watcher services). These servers can be VMs running on your local
+   machine via VirtualBox if you prefer. DevStack currently recommends that
+   you use Ubuntu 14.04 LTS. The servers should also have connections to the
+   same network such that they are all able to communicate with one another.
+
+#. For each server, clone the DevStack repository and create the stack user::
+
+       sudo apt-get update
+       sudo apt-get install git
+       git clone https://git.openstack.org/openstack-dev/devstack
+       sudo ./devstack/tools/create-stack-user.sh
+
+   Now you have a stack user that is used to run the DevStack processes. You
+   may want to give your stack user a password to allow SSH via a password::
+
+       sudo passwd stack
+
+#. Switch to the stack user and clone the DevStack repo again::
+
+       sudo su stack
+       cd ~
+       git clone https://git.openstack.org/openstack-dev/devstack
+
+#. For each compute node, copy the provided `local.conf.compute`_ example file
+   to the compute node's system at ~/devstack/local.conf. Make sure the
+   HOST_IP and SERVICE_HOST values are changed appropriately - i.e., HOST_IP
+   is set to the IP address of the compute node and SERVICE_HOST is set to the
+   IP address of the controller node.
+
+   If you need specific metrics collected (or want to use something other
+   than Ceilometer), be sure to configure it. For example, in the
+   `local.conf.compute`_ example file, the appropriate ceilometer plugins and
+   services are enabled and disabled. If you were using something other than
+   Ceilometer, then you would likely want to configure it likewise. The
+   example file also sets the compute monitors nova configuration option to
+   use the CPU virt driver. If you needed other metrics, it may be necessary
+   to configure similar configuration options for the projects providing those
+   metrics.
+
+#. For the controller node, copy the provided `local.conf.controller`_ example
+   file to the controller node's system at ~/devstack/local.conf. Make sure
+   the HOST_IP value is changed appropriately - i.e., HOST_IP is set to the IP
+   address of the controller node.
+
+   Note: if you want to use another Watcher git repository (such as a local
+   one), then change the enable plugin line::
+
+       enable_plugin watcher <your_local_git_repo> [optional_branch]
+
+   If you do this, then the Watcher DevStack plugin will try to pull the
+   python-watcherclient repo from <your_local_git_repo>/../, so either make
+   sure that is also available or specify WATCHERCLIENT_REPO in the local.conf
+   file.
+
+   Note: if you want to use a specific branch, specify WATCHER_BRANCH in the
+   local.conf file. By default it will use the master branch.
+
+#. Start stacking from the controller node::
+
+       ./devstack/stack.sh
+
+#. Start stacking on each of the compute nodes using the same command.
+
+#. Configure the environment for live migration via NFS. See the
+   `Multi-Node DevStack Environment`_ section for more details.

+
+Multi-Node DevStack Environment
+===============================
+
+Since deploying Watcher with only a single compute node is not very useful, a
+few tips are given here for enabling a multi-node environment with live
+migration.
+
+Configuring NFS Server
+----------------------
+
+If you would like to use live migration for shared storage, then the controller
+can serve as the NFS server if needed::
+
+    sudo apt-get install nfs-kernel-server
+    sudo mkdir -p /nfs/instances
+    sudo chown stack:stack /nfs/instances
+
+Add an entry to `/etc/exports` with the appropriate gateway and netmask
+information::
+
+    /nfs/instances <gateway>/<netmask>(rw,fsid=0,insecure,no_subtree_check,async,no_root_squash)
+
+Export the NFS directories::
+
+    sudo exportfs -ra
+
+Make sure the NFS server is running::
+
+    sudo service nfs-kernel-server status
+
+If the server is not running, then start it::
+
+    sudo service nfs-kernel-server start
+
+Configuring NFS on Compute Node
+-------------------------------
+
+Each compute node needs to use the NFS server to hold the instance data::
+
+    sudo apt-get install rpcbind nfs-common
+    mkdir -p /opt/stack/data/instances
+    sudo mount <nfs-server-ip>:/nfs/instances /opt/stack/data/instances
+
+If you would like to have the NFS directory automatically mounted on reboot,
+then add the following to `/etc/fstab`::
+
+    <nfs-server-ip>:/nfs/instances /opt/stack/data/instances nfs auto 0 0
+
+Edit `/etc/libvirt/libvirtd.conf` to make sure the following values are set::
+
+    listen_tls = 0
+    listen_tcp = 1
+    auth_tcp = "none"
+
+Edit `/etc/default/libvirt-bin`::
+
+    libvirt_opts="-d -l"
+
+Restart the libvirt service::
+
+    sudo service libvirt-bin restart
+
+Setting up SSH keys between compute nodes to enable live migration
+------------------------------------------------------------------
+
+In order for live migration to work, SSH keys need to be exchanged between
+each compute node:
+
+1. The SOURCE root user's public RSA key (likely in /root/.ssh/id_rsa.pub)
+   needs to be in the DESTINATION stack user's authorized_keys file
+   (~stack/.ssh/authorized_keys). This can be accomplished by manually
+   copying the contents from the file on the SOURCE to the DESTINATION. If
+   you have a password configured for the stack user, then you can use the
+   following command to accomplish the same thing::
+
+        ssh-copy-id -i /root/.ssh/id_rsa.pub stack@DESTINATION
+
+2. The DESTINATION host's public ECDSA key (/etc/ssh/ssh_host_ecdsa_key.pub)
+   needs to be in the SOURCE root user's known_hosts file
+   (/root/.ssh/known_hosts). This can be accomplished by running the
+   following on the SOURCE machine (hostname must be used)::
+
+        ssh-keyscan -H DEST_HOSTNAME | sudo tee -a /root/.ssh/known_hosts
+
+In essence, this means that every compute node's root user's public RSA key
+must exist in every other compute node's stack user's authorized_keys file and
+every compute node's public ECDSA key needs to be in every other compute
+node's root user's known_hosts file.
+
+
+Environment final checkup
+-------------------------
+
+If you are willing to make sure everything is in order in your DevStack
+environment, you can run the Watcher Tempest tests which will validate its API
+but also that you can perform the typical Watcher workflows. To do so, have a
+look at the :ref:`Tempest tests <tempest_tests>` section which will explain to
+you how to run them.

-
-Action
-======
-
-An :ref:`Action <action_definition>` is what enables Watcher to transform the
-current state of a :ref:`Cluster <cluster_definition>` after an
-:ref:`Audit <audit_definition>`.
-
-An :ref:`Action <action_definition>` is an atomic task which changes the
-current state of a target :ref:`Managed resource <managed_resource_definition>`
-of the OpenStack :ref:`Cluster <cluster_definition>` such as:
-
--  Live migration of an instance from one compute node to another compute
-   node with Nova
--  Changing the power level of a compute node (ACPI level, ...)
--  Changing the current state of an hypervisor (enable or disable) with Nova
-
-In most cases, an :ref:`Action <action_definition>` triggers some concrete
-commands on an existing OpenStack module (Nova, Neutron, Cinder, Ironic, etc.).
-
-An :ref:`Action <action_definition>` has a life-cycle and its current state may
-be one of the following:
-
--  **PENDING** : the :ref:`Action <action_definition>` has not been executed
-   yet by the :ref:`Watcher Applier <watcher_applier_definition>`
--  **ONGOING** : the :ref:`Action <action_definition>` is currently being
-   processed by the :ref:`Watcher Applier <watcher_applier_definition>`
--  **SUCCEEDED** : the :ref:`Action <action_definition>` has been executed
-   successfully
--  **FAILED** : an error occured while trying to execute the
-   :ref:`Action <action_definition>`
--  **DELETED** : the :ref:`Action <action_definition>` is still stored in the
-   :ref:`Watcher database <watcher_database_definition>` but is not returned
-   any more through the Watcher APIs.
--  **CANCELLED** : the :ref:`Action <action_definition>` was in **PENDING** or
-   **ONGOING** state and was cancelled by the
-   :ref:`Administrator <administrator_definition>`
-
-.. _action_plan_definition:
-
-Action Plan
-===========
-
-An :ref:`Action Plan <action_plan_definition>` is a flow of
-:ref:`Actions <action_definition>` that should be executed in order to satisfy
-a given :ref:`Goal <goal_definition>`.
-
-An :ref:`Action Plan <action_plan_definition>` is generated by Watcher when an
-:ref:`Audit <audit_definition>` is successful which implies that the :ref:`Strategy <strategy_definition>`
-which was used has found a :ref:`Solution <solution_definition>` to achieve the
-:ref:`Goal <goal_definition>` of this :ref:`Audit <audit_definition>`.
-
-In the default implementation of Watcher, an :ref:`Action Plan <action_plan_definition>`
-is only composed of successive :ref:`Actions <action_definition>`
-(i.e., a Workflow of :ref:`Actions <action_definition>` belonging to a unique
-branch).
-
-However, Watcher provides abstract interfaces for many of its components,
-allowing other implementations to generate and handle more complex :ref:`Action Plan(s) <action_plan_definition>`
-composed of two types of Action Item(s):
-
--  simple :ref:`Actions <action_definition>`: atomic tasks, which means it
-   can not be split into smaller tasks or commands from an OpenStack point of
-   view.
--  composite Actions: which are composed of several simple :ref:`Actions <action_definition>`
-   ordered in sequential and/or parallel flows.
-
-An :ref:`Action Plan <action_plan_definition>` may be described using
-standard workflow model description formats such as
-`Business Process Model and Notation 2.0 (BPMN 2.0) <http://www.omg.org/spec/BPMN/2.0/>`_
-or `Unified Modeling Language (UML) <http://www.uml.org/>`_.
-
-An :ref:`Action Plan <action_plan_definition>` has a life-cycle and its current
-state may be one of the following:
-
--  **RECOMMENDED** : the :ref:`Action Plan <action_plan_definition>` is waiting
-   for a validation from the :ref:`Administrator <administrator_definition>`
--  **ONGOING** : the :ref:`Action Plan <action_plan_definition>` is currently
-   being processed by the :ref:`Watcher Applier <watcher_applier_definition>`
--  **SUCCEEDED** : the :ref:`Action Plan <action_plan_definition>` has been
-   executed successfully (i.e. all :ref:`Actions <action_definition>` that it
-   contains have been executed successfully)
--  **FAILED** : an error occured while executing the
-   :ref:`Action Plan <action_plan_definition>`
--  **DELETED** : the :ref:`Action Plan <action_plan_definition>` is still
-   stored in the :ref:`Watcher database <watcher_database_definition>` but is
-   not returned any more through the Watcher APIs.
--  **CANCELLED** : the :ref:`Action Plan <action_plan_definition>` was in
-   **PENDING** or **ONGOING** state and was cancelled by the
-   :ref:`Administrator <administrator_definition>`
-
-.. _administrator_definition:
-
-Administrator
-=============
-
-The :ref:`Administrator <administrator_definition>` is any user who has admin
-access on the OpenStack cluster. This user is allowed to create new projects
-for tenants, create new users and assign roles to each user.
-
-The :ref:`Administrator <administrator_definition>` usually has remote access
-to any host of the cluster in order to change the configuration and restart any
-OpenStack service, including Watcher.
-
-In the context of Watcher, the :ref:`Administrator <administrator_definition>`
-is a role for users which allows them to run any Watcher commands, such as:
-
--  Create/Delete an :ref:`Audit Template <audit_template_definition>`
--  Launch an :ref:`Audit <audit_definition>`
--  Get the :ref:`Action Plan <action_plan_definition>`
--  Launch a recommended :ref:`Action Plan <action_plan_definition>` manually
--  Archive previous :ref:`Audits <audit_definition>` and :ref:`Action Plans <action_plan_definition>`
-
-
-The :ref:`Administrator <administrator_definition>` is also allowed to modify
-any Watcher configuration files and to restart Watcher services.
-
-.. _audit_definition:
-
-Audit
-=====
-
-In the Watcher system, an :ref:`Audit <audit_definition>` is a request for
-optimizing a :ref:`Cluster <cluster_definition>`.
-
-The optimization is done in order to satisfy one :ref:`Goal <goal_definition>`
-on a given :ref:`Cluster <cluster_definition>`.
-
-For each :ref:`Audit <audit_definition>`, the Watcher system generates an
-:ref:`Action Plan <action_plan_definition>`.
-
-An :ref:`Audit <audit_definition>` has a life-cycle and its current state may
-be one of the following:
-
--  **PENDING** : a request for an :ref:`Audit <audit_definition>` has been
-   submitted (either manually by the
-   :ref:`Administrator <administrator_definition>` or automatically via some
-   event handling mechanism) and is in the queue for being processed by the
-   :ref:`Watcher Decision Engine <watcher_decision_engine_definition>`
--  **ONGOING** : the :ref:`Audit <audit_definition>` is currently being
-   processed by the :ref:`Watcher Decision Engine <watcher_decision_engine_definition>`
--  **SUCCEEDED** : the :ref:`Audit <audit_definition>` has been executed
-   successfully (note that it may not necessarily produce a
-   :ref:`Solution <solution_definition>`).
--  **FAILED** : an error occured while executing the
-   :ref:`Audit <audit_definition>`
--  **DELETED** : the :ref:`Audit <audit_definition>` is still stored in the
-   :ref:`Watcher database <watcher_database_definition>` but is not returned
-   any more through the Watcher APIs.
--  **CANCELLED** : the :ref:`Audit <audit_definition>` was in **PENDING** or
-   **ONGOING** state and was cancelled by the
-   :ref:`Administrator <administrator_definition>`
-
-.. _audit_template_definition:
-
-Audit Template
-==============
-
-An :ref:`Audit <audit_definition>` may be launched several times with the same
-settings (:ref:`Goal <goal_definition>`, thresholds, ...). Therefore it makes
-sense to save those settings in some sort of Audit preset object, which is
-known as an :ref:`Audit Template <audit_template_definition>`.
-
-An :ref:`Audit Template <audit_template_definition>` contains at least the
-:ref:`Goal <goal_definition>` of the :ref:`Audit <audit_definition>`.
-
-It may also contain some error handling settings indicating whether:
-
--  :ref:`Watcher Applier <watcher_applier_definition>` stops the entire operation
--  :ref:`Watcher Applier <watcher_applier_definition>` performs a rollback
-
-and how many retries should be attempted before failure occurs (also the latter
-can be complex: for example the scenario in which there are many first-time
-failures on ultimately successful :ref:`Actions <action_definition>`).
-
-Moreover, an :ref:`Audit Template <audit_template_definition>` may contain some
-settings related to the level of automation for the
-:ref:`Action Plan <action_plan_definition>` that will be generated by the
-:ref:`Audit <audit_definition>`.
-A flag will indicate whether the :ref:`Action Plan <action_plan_definition>`
-will be launched automatically or will need a manual confirmation from the
-:ref:`Administrator <administrator_definition>`.
-
-Last but not least, an :ref:`Audit Template <audit_template_definition>` may
-contain a list of extra parameters related to the
-:ref:`Strategy <strategy_definition>` configuration. These parameters can be
-provided as a list of key-value pairs.
-
-.. _availability_zone_definition:
-
-Availability Zone
-=================
-
-Please, read `the official OpenStack definition of an Availability Zone <http://docs.openstack.org/developer/nova/aggregates.html#availability-zones-azs>`_.
-
-.. _cluster_definition:
-
-Cluster
-=======
-
-A :ref:`Cluster <cluster_definition>` is a set of physical machines which
-provide compute, storage and networking resources and are managed by the same
-OpenStack Controller node.
-A :ref:`Cluster <cluster_definition>` represents a set of resources that a
-cloud provider is able to offer to his/her
-:ref:`customers <customer_definition>`.
-
-A data center may contain several clusters.
-
-The :ref:`Cluster <cluster_definition>` may be divided in one or several
-:ref:`Availability Zone(s) <availability_zone_definition>`.
-
-.. _cluster_data_model_definition:
-
-Cluster Data Model
-==================
-
-A :ref:`Cluster Data Model <cluster_data_model_definition>` is a logical
-representation of the current state and topology of the :ref:`Cluster <cluster_definition>`
-:ref:`Managed resources <managed_resource_definition>`.
-
-It is represented as a set of :ref:`Managed resources <managed_resource_definition>`
-(which may be a simple tree or a flat list of key-value pairs)
-which enables Watcher :ref:`Strategies <strategy_definition>` to know the
-current relationships between the different
-:ref:`resources <managed_resource_definition>`) of the
-:ref:`Cluster <cluster_definition>` during an :ref:`Audit <audit_definition>`
-and enables the :ref:`Strategy <strategy_definition>` to request information
-such as:
-
--  What compute nodes are in a given :ref:`Availability Zone <availability_zone_definition>`
-   or a given :ref:`Host Aggregate <host_aggregates_definition>` ?
--  What :ref:`Instances <instance_definition>` are hosted on a given compute
-   node ?
--  What is the current load of a compute node ?
--  What is the current free memory of a compute node ?
--  What is the network link between two compute nodes ?
--  What is the available bandwidth on a given network link ?
--  What is the current space available on a given virtual disk of a given
-   :ref:`Instance <instance_definition>` ?
--  What is the current state of a given :ref:`Instance <instance_definition>` ?
--  ...
-
-In a word, this data model enables the :ref:`Strategy <strategy_definition>`
-to know:
-
--  the current topology of the :ref:`Cluster <cluster_definition>`
--  the current capacity for each :ref:`Managed resource <managed_resource_definition>`
--  the current amount of used/free space for each :ref:`Managed resource <managed_resource_definition>`
--  the current state of each :ref:`Managed resources <managed_resource_definition>`
-
-In the Watcher project, we aim at providing a generic and very basic
-:ref:`Cluster Data Model <cluster_data_model_definition>` for each
-:ref:`Goal <goal_definition>`, usable in the associated
-:ref:`Strategies <strategy_definition>` through some helper classes in order
-to:
-
--  simplify the development of a new
-   :ref:`Strategy <strategy_definition>` for a given
-   :ref:`Goal <goal_definition>` when there already are some existing
-   :ref:`Strategies <strategy_definition>` associated to the same
-   :ref:`Goal <goal_definition>`
--  avoid duplicating the same code in several
-   :ref:`Strategies <strategy_definition>` associated to the same
-   :ref:`Goal <goal_definition>`
--  have a better consistency between the different
-   :ref:`Strategies <strategy_definition>` for a given
-   :ref:`Goal <goal_definition>`
--  avoid any strong coupling with any external
-   :ref:`Cluster Data Model <cluster_data_model_definition>`
-   (the proposed data model acts as a pivot data model)
-
-There may be various :ref:`generic and basic Cluster Data Models <cluster_data_model_definition>`
-proposed in Watcher helpers, each of them being adapted to achieving a given
-:ref:`Goal <goal_definition>`:
-
--  For example, for a
-   :ref:`Goal <goal_definition>` which aims at optimizing the network
-   :ref:`resources <managed_resource_definition>` the
-   :ref:`Strategy <strategy_definition>` may need to know which
-   :ref:`resources <managed_resource_definition>` are communicating together.
--  Whereas for a :ref:`Goal <goal_definition>` which aims at optimizing thermal
-   and power conditions, the :ref:`Strategy <strategy_definition>` may need to
-   know the location of each compute node in the racks and the location of each
-   rack in the room.
-
-Note however that a developer can use his/her own
-:ref:`Cluster Data Model <cluster_data_model_definition>` if the proposed data
-model does not fit his/her needs as long as the :ref:`Strategy <strategy_definition>`
-is able to produce a :ref:`Solution <solution_definition>` for the requested :ref:`Goal <goal_definition>`.
-For example, a developer could rely on the Nova Data Model to optimize some
-compute resources.
-
-The :ref:`Cluster Data Model <cluster_data_model_definition>` may be persisted
-in any appropriate storage system (SQL database, NoSQL database, JSON file,
-XML File, In Memory Database, ...).
-
-.. _cluster_history_definition:
-
-Cluster History
-===============
-
-The :ref:`Cluster History <cluster_history_definition>` contains all the
-previously collected timestamped data such as metrics and events associated
-to any :ref:`managed resource <managed_resource_definition>` of the
-:ref:`Cluster <cluster_definition>`.
-
-Just like the :ref:`Cluster Data Model <cluster_data_model_definition>`, this
-history may be used by any :ref:`Strategy <strategy_definition>` in order to
-find the most optimal :ref:`Solution <solution_definition>` during an
-:ref:`Audit <audit_definition>`.
-
-In the Watcher project, a generic :ref:`Cluster History <cluster_history_definition>`
-API is proposed with some helper classes in order to :
-
--  share a common measurement (events or metrics) naming based on what is
-   defined in Ceilometer. See `the full list of available measurements <http://docs.openstack.org/admin-guide-cloud/telemetry-measurements.html>`_
--  share common meter types (Cumulative, Delta, Gauge) based on what is
-   defined in Ceilometer. See `the full list of meter types <http://docs.openstack.org/admin-guide-cloud/telemetry-measurements.html>`_
--  simplify the development of a new :ref:`Strategy <strategy_definition>`
--  avoid duplicating the same code in several :ref:`Strategies <strategy_definition>`
--  have a better consistency between the different :ref:`Strategies <strategy_definition>`
--  avoid any strong coupling with any external metrics/events storage system
-   (the proposed API and measurement naming system acts as a pivot format)
-
-Note however that a developer can use his/her own history management system if
-the Ceilometer system does not fit his/her needs as long as the
-:ref:`Strategy <strategy_definition>` is able to produce a
-:ref:`Solution <solution_definition>` for the requested
-:ref:`Goal <goal_definition>`.
-
-The :ref:`Cluster History <cluster_history_definition>` data may be persisted
-in any appropriate storage system (InfluxDB, OpenTSDB, MongoDB,...).
-
-.. _controller_node_definition:
-
-Controller Node
-===============
-
-A controller node is a machine that typically runs the following core OpenStack
-services:
-
--  Keystone: for identity and service management
--  Cinder scheduler: for volumes management
--  Glance controller: for image management
--  Neutron controller: for network management
--  Nova controller: for global compute resources management with services such as
-   nova-scheduler, nova-conductor and nova-network
-
-In many configurations, Watcher will reside on a controller node even if it
-can potentially be hosted on a dedicated machine.
-
-.. _compute_node_definition:
-
-Compute node
-============
-
-Please, read `the official OpenStack definition of a Compute Node <http://docs.openstack.org/openstack-ops/content/compute_nodes.html>`_.
-
-.. _customer_definition:
-
-Customer
-========
-
-A :ref:`Customer <customer_definition>` is the person or company which
-subscribes to the cloud provider offering. A customer may have several :ref:`Project(s) <project_definition>`
-hosted on the same :ref:`Cluster <cluster_definition>` or dispatched on
-different clusters.
-
-In the private cloud context, the :ref:`Customers <customer_definition>` are
-different groups within the same organization (different departments, project
-teams, branch offices and so on). Cloud infrastructure includes the ability to
-precisely track each customer's service usage so that it can be charged back to
-them, or at least reported to them.
-
-.. _goal_definition:
-
-Goal
-====
-
-A :ref:`Goal <goal_definition>` is a human readable, observable and measurable
-end result having one objective to be achieved.
-
-Here are some examples of :ref:`Goals <goal_definition>`:
-
--  minimize the energy consumption
--  minimize the number of compute nodes (consolidation)
--  balance the workload among compute nodes
--  minimize the license cost (some softwares have a licensing model which is
-   based on the number of sockets or cores where the software is deployed)
--  find the most appropriate moment for a planned maintenance on a
-   given group of host (which may be an entire availability zone):
-   power supply replacement, cooling system replacement, hardware
-   modification, ...
-
-
-.. _host_aggregates_definition:
-
-Host Aggregate
-==============
-
-Please, read `the official OpenStack definition of a Host Aggregate <http://docs.openstack.org/developer/nova/aggregates.html>`_.
-
-.. _instance_definition:
-
-Instance
-========
-
-A running virtual machine, or a virtual machine in a known state such as
-suspended, that can be used like a hardware server.
-
-.. _managed_resource_definition:
-
-Managed resource
-================
-
-A :ref:`Managed resource <managed_resource_definition>` is one instance of
-:ref:`Managed resource type <managed_resource_type_definition>` in a topology
-with particular properties and dependencies on other
-:ref:`Managed resources <managed_resource_definition>` (relationships).
-
-For example, a :ref:`Managed resource <managed_resource_definition>` can be one
-virtual machine (i.e., an :ref:`instance <instance_definition>`) hosted on a
-:ref:`compute node <compute_node_definition>` and connected to another virtual
-machine through a network link (represented also as a
-:ref:`Managed resource <managed_resource_definition>` in the
-:ref:`Cluster Data Model <cluster_data_model_definition>`).
-
-.. _managed_resource_type_definition:
-
-Managed resource type
-=====================
-
-A :ref:`Managed resource type <managed_resource_definition>` is a type of
-hardware or software element of the :ref:`Cluster <cluster_definition>` that
-the Watcher system can act on.
-
-Here are some examples of
-:ref:`Managed resource types <managed_resource_definition>`:
-
--  `Nova Host Aggregates <http://docs.openstack.org/developer/heat/template_guide/openstack.html#OS::Nova::HostAggregate>`_
--  `Nova Servers <http://docs.openstack.org/developer/heat/template_guide/openstack.html#OS::Nova::Server>`_
--  `Cinder Volumes <http://docs.openstack.org/developer/heat/template_guide/openstack.html#OS::Cinder::Volume>`_
--  `Neutron Routers <http://docs.openstack.org/developer/heat/template_guide/openstack.html#OS::Neutron::Router>`_
--  `Neutron Networks <http://docs.openstack.org/developer/heat/template_guide/openstack.html#OS::Neutron::Net>`_
--  `Neutron load-balancers <http://docs.openstack.org/developer/heat/template_guide/openstack.html#OS::Neutron::LoadBalancer>`_
--  `Sahara Hadoop Cluster <http://docs.openstack.org/developer/heat/template_guide/openstack.html#OS::Sahara::Cluster>`_
--  ...
-
-It can be any of the `the official list of available resource types defined in OpenStack for HEAT <http://docs.openstack.org/developer/heat/template_guide/openstack.html>`_.
-
-.. _efficiency_definition:
-
-Optimization Efficiency
-=======================
-
-The :ref:`Optimization Efficiency <efficiency_definition>` is the objective
-measure of how much of the :ref:`Goal <goal_definition>` has been achieved in
-respect with constraints and :ref:`SLAs <sla_definition>` defined by the
-:ref:`Customer <customer_definition>`.
-
-The way efficiency is evaluated will depend on the :ref:`Goal <goal_definition>`
-to achieve.
-
-Of course, the efficiency will be relevant only as long as the :ref:`Action Plan <action_plan_definition>`
-is relevant (i.e., the current state of the :ref:`Cluster <cluster_definition>`
-has not changed in a way that a new :ref:`Audit <audit_definition>` would need
-to be launched).
-
-For example, if the :ref:`Goal <goal_definition>` is to lower the energy
-consumption, the :ref:`Efficiency <efficiency_definition>` will be computed
-using several indicators (KPIs):
-
--  the percentage of energy gain (which must be the highest possible)
--  the number of :ref:`SLA violations <sla_violation_definition>`
-   (which must be the lowest possible)
--  the number of virtual machine migrations (which must be the lowest possible)
-
-All those indicators (KPIs) are computed within a given timeframe, which is the
-time taken to execute the whole :ref:`Action Plan <action_plan_definition>`.
-
-The efficiency also enables the :ref:`Administrator <administrator_definition>`
-to objectively compare different :ref:`Strategies <strategy_definition>` for
-the same goal and same workload of the :ref:`Cluster <cluster_definition>`.
-
-.. _project_definition:
-
-Project
-=======
-
-:ref:`Projects <project_definition>` represent the base unit of “ownership”
-in OpenStack, in that all :ref:`resources <managed_resource_definition>` in
-OpenStack should be owned by a specific :ref:`project <project_definition>`.
-In OpenStack Identity, a :ref:`project <project_definition>` must be owned by a
-specific domain.
-
-Please, read `the official OpenStack definition of a Project <http://docs.openstack.org/glossary/content/glossary.html>`_.
-
-.. _sla_definition:
-
-SLA
-===
-
-:ref:`SLA <sla_definition>` means Service Level Agreement.
-
-The resources are negotiated between the :ref:`Customer <customer_definition>`
-and the Cloud Provider in a contract.
-
-Most of the time, this contract is composed of two documents:
-
--  :ref:`SLA <sla_definition>` : Service Level Agreement
--  :ref:`SLO <slo_definition>` : Service Level Objectives
-
-Note that the :ref:`SLA <sla_definition>` is more general than the
-:ref:`SLO <slo_definition>` in the sense that the former specifies what service
-is to be provided, how it is supported, times, locations, costs, performance,
-and responsibilities of the parties involved while the
-:ref:`SLO <slo_definition>` focuses on more measurable characteristics such as
-availability, throughput, frequency, response time or quality.
-
-You can also read `the Wikipedia page for SLA <https://en.wikipedia.org/wiki/Service-level_agreement>`_
-which provides a good definition.
-
-.. _sla_violation_definition:
-
-SLA violation
-=============
-
-A :ref:`SLA violation <sla_violation_definition>` happens when a :ref:`SLA <sla_definition>`
-defined with a given :ref:`Customer <customer_definition>` could not be
-respected by the cloud provider within the timeframe defined by the official
-contract document.
-
-.. _slo_definition:
-
-SLO
-===
-
-A Service Level Objective (SLO) is a key element of a :ref:`SLA <sla_definition>`
-between a service provider and a :ref:`Customer <customer_definition>`. SLOs
-are agreed as a means of measuring the performance of the Service Provider and
-are outlined as a way of avoiding disputes between the two parties based on
-misunderstanding.
-
-You can also read `the Wikipedia page for SLO <https://en.wikipedia.org/wiki/Service_level_objective>`_
-which provides a good definition.
-
-.. _solution_definition:
-
-Solution
-========
-
-A :ref:`Solution <solution_definition>` is a set of :ref:`Actions <action_definition>`
-generated by a :ref:`Strategy <strategy_definition>` (i.e., an algorithm) in
-order to achieve the :ref:`Goal <goal_definition>` of an :ref:`Audit <audit_definition>`.
-
-A :ref:`Solution <solution_definition>` is different from an
-:ref:`Action Plan <action_plan_definition>` because it contains the
-non-scheduled list of :ref:`Actions <action_definition>` which is produced by a
-:ref:`Strategy <strategy_definition>`. In other words, the list of Actions in
-a :ref:`Solution <solution_definition>` has not yet been re-ordered by the
-:ref:`Watcher Planner <watcher_planner_definition>`.
-
-Note that some algorithms (i.e. :ref:`Strategies <strategy_definition>`) may
-generate several :ref:`Solutions <solution_definition>`. This gives rise to the
-problem of determining which :ref:`Solution <solution_definition>` should be
-applied.
-
-Two approaches to dealing with this can be envisaged:
-
--  **fully automated mode**: only the :ref:`Solution <solution_definition>` with
-   the highest ranking (i.e., the highest
-   :ref:`Optimization Efficiency <efficiency_definition>`)
-   will be sent to the :ref:`Watcher Planner <watcher_planner_definition>` and
-   translated into concrete :ref:`Actions <action_definition>`.
--  **manual mode**: several :ref:`Solutions <solution_definition>` are proposed
-   to the :ref:`Administrator <administrator_definition>` with a detailed
-   measurement of the estimated
-   :ref:`Optimization Efficiency <efficiency_definition>` and he/she decides
-   which one will be launched.
-
-.. _strategy_definition:
-
-Strategy
-========
-
-A :ref:`Strategy <strategy_definition>` is an algorithm implementation which is
-able to find a :ref:`Solution <solution_definition>` for a given :ref:`Goal <goal_definition>`.
-
-There may be several potential strategies which are able to achieve the same
-:ref:`Goal <goal_definition>`. This is why it is possible to configure which
-specific :ref:`Strategy <strategy_definition>` should be used for each :ref:`Goal <goal_definition>`.
-
-Some strategies may provide better optimization results but may take more time
-to find an optimal :ref:`Solution <solution_definition>`.
-
-When a new :ref:`Goal <goal_definition>` is added to the Watcher configuration,
-at least one default associated :ref:`Strategy <strategy_definition>` should be
-provided as well.

-.. _watcher_database_definition:
-
-Watcher Database
-================
-
-This database stores all the Watcher domain objects which can be requested

-Watcher Decision Engine
-=======================
-
-This component is responsible for computing a set of potential optimization
-:ref:`Actions <action_definition>` in order to fulfill the :ref:`Goal <goal_definition>`
-of an :ref:`Audit <audit_definition>`.
-
-It first reads the parameters of the :ref:`Audit <audit_definition>` from the

-:ref:`Goal <goal_definition>` to achieve.
-
-It then selects the most appropriate :ref:`Strategy <strategy_definition>`
-depending on how Watcher was configured for this :ref:`Goal <goal_definition>`.
-
-The :ref:`Strategy <strategy_definition>` is then executed and generates a set
-of :ref:`Actions <action_definition>` which are scheduled in time by the
-:ref:`Watcher Planner <watcher_planner_definition>` (i.e., it generates an
-:ref:`Action Plan <action_plan_definition>`).

-
-Watcher Planner
-===============
-
-The :ref:`Watcher Planner <watcher_planner_definition>` is part of the
-:ref:`Watcher Decision Engine <watcher_decision_engine_definition>`.
-
-This module takes the set of :ref:`Actions <action_definition>` generated by a
-:ref:`Strategy <strategy_definition>` and builds the design of a workflow which
-defines how-to schedule in time those different
-:ref:`Actions <action_definition>` and for each
-:ref:`Action <action_definition>` what are the prerequisite conditions.
-
-It is important to schedule :ref:`Actions <action_definition>` in time in order
-to prevent overload of the :ref:`Cluster <cluster_definition>` while applying
-the :ref:`Action Plan <action_plan_definition>`. For example, it is important
-not to migrate too many instances at the same time in order to avoid a network
-congestion which may decrease the :ref:`SLA <sla_definition>` for

+
+==================
+Build a new action
+==================
+
+Watcher Applier has an external :ref:`action <action_definition>` plugin
+interface which gives anyone the ability to integrate an external
+:ref:`action <action_definition>` in order to extend the initial set of actions
+Watcher provides.
+
+This section gives some guidelines on how to implement and integrate custom
+actions with Watcher.
+
+
+Creating a new plugin
+=====================
+
+First of all you have to extend the base :py:class:`BaseAction` class which
+defines a set of abstract methods and/or properties that you will have to
+implement:
+
+ - The :py:attr:`~.BaseAction.schema` is an abstract property that you have to
+   implement. This is the first function to be called by the
+   :ref:`applier <watcher_applier_definition>` before any further processing
+   and its role is to validate the input parameters that were provided to it.
+ - The :py:meth:`~.BaseAction.precondition` is called before the execution of
+   an action. This method is a hook that can be used to perform some
+   initializations or to make some more advanced validation on its input
+   parameters. If you wish to block the execution based on this factor, you
+   simply have to ``raise`` an exception.
+ - The :py:meth:`~.BaseAction.postcondition` is called after the execution of
+   an action. As this function is called regardless of whether an action
+   succeeded or not, this can prove itself useful to perform cleanup
+   operations.
+ - The :py:meth:`~.BaseAction.execute` is the main component of an action.
+   This is where you should implement the logic of your action.
+ - The :py:meth:`~.BaseAction.revert` allows you to roll back the targeted
+   resource to its original state following a faulty execution. Indeed, this
+   method is called by the workflow engine whenever an action raises an
+   exception.
+
+Here is an example showing how you can write a plugin called ``DummyAction``:
+
+.. code-block:: python
+
+    # Filepath = <PROJECT_DIR>/thirdparty/dummy.py
+    # Import path = thirdparty.dummy
+    import voluptuous
+
+    from watcher.applier.actions import base
+
+
+    class DummyAction(base.BaseAction):
+
+        @property
+        def schema(self):
+            return voluptuous.Schema({})
+
+        def execute(self):
+            # Does nothing
+            pass  # Only returning False is considered as a failure
+
+        def revert(self):
+            # Does nothing
+            pass
+
+        def precondition(self):
+            # No pre-checks are done here
+            pass
+
+        def postcondition(self):
+            # Nothing done here
+            pass
+
+
+This implementation is the most basic one. So if you want to have more advanced
+examples, have a look at the implementation of the actions already provided
+by Watcher like.
+To get a better understanding on how to implement a more advanced action,
+have a look at the :py:class:`~watcher.applier.actions.migration.Migrate`
+class.
+
+Input validation
+----------------
+
+As you can see in the previous example, we are using `Voluptuous`_ to validate
+the input parameters of an action. So if you want to learn more about how to
+work with `Voluptuous`_, you can have a look at their `documentation`_:
+
+.. _Voluptuous: https://github.com/alecthomas/voluptuous
+.. _documentation: https://github.com/alecthomas/voluptuous/blob/master/README.md
+
+
+Define configuration parameters
+===============================
+
+At this point, you have a fully functional action. However, in more complex
+implementation, you may want to define some configuration options so one can
+tune the action to its needs. To do so, you can implement the
+:py:meth:`~.Loadable.get_config_opts` class method as followed:
+
+.. code-block:: python
+
+    from oslo_config import cfg
+
+    class DummyAction(base.BaseAction):
+
+        # [...]
+
+        def execute(self):
+            assert self.config.test_opt == 0
+
+        def get_config_opts(self):
+            return [
+                cfg.StrOpt('test_opt', help="Demo Option.", default=0),
+                # Some more options ...
+            ]
+
+The configuration options defined within this class method will be included
+within the global ``watcher.conf`` configuration file under a section named by
+convention: ``{namespace}.{plugin_name}``. In our case, the ``watcher.conf``
+configuration would have to be modified as followed:
+
+.. code-block:: ini
+
+    [watcher_actions.dummy]
+    # Option used for testing.
+    test_opt = test_value
+
+Then, the configuration options you define within this method will then be
+injected in each instantiated object via the  ``config`` parameter of the
+:py:meth:`~.BaseAction.__init__` method.
+
+
+Abstract Plugin Class
+=====================
+
+Here below is the abstract ``BaseAction`` class that every single action
+should implement:
+
+.. autoclass:: watcher.applier.actions.base.BaseAction
+    :members:
+    :special-members: __init__
+    :noindex:
+
+    .. py:attribute:: schema
+
+        Defines a Schema that the input parameters shall comply to
+
+        :returns: A schema declaring the input parameters this action should be
+                  provided along with their respective constraints
+                  (e.g. type, value range, ...)
+        :rtype: :py:class:`voluptuous.Schema` instance
+
+
+Register a new entry point
+==========================
+
+In order for the Watcher Applier to load your new action, the
+action must be registered as a named entry point under the
+``watcher_actions`` entry point of your ``setup.py`` file. If you are using
+pbr_, this entry point should be placed in your ``setup.cfg`` file.
+
+The name you give to your entry point has to be unique.
+
+Here below is how you would proceed to register ``DummyAction`` using pbr_:
+
+.. code-block:: ini
+
+    [entry_points]
+    watcher_actions =
+        dummy = thirdparty.dummy:DummyAction
+
+.. _pbr: http://docs.openstack.org/developer/pbr/
+
+
+Using action plugins
+====================
+
+The Watcher Applier service will automatically discover any installed plugins
+when it is restarted. If a Python package containing a custom plugin is
+installed within the same environment as Watcher, Watcher will automatically
+make that plugin available for use.
+
+At this point, you can use your new action plugin in your :ref:`strategy plugin
+<implement_strategy_plugin>` if you reference it via the use of the
+:py:meth:`~.Solution.add_action` method:
+
+.. code-block:: python
+
+    # [...]
+    self.solution.add_action(
+        action_type="dummy",  # Name of the entry point we registered earlier
+        applies_to="",
+        input_parameters={})
+
+By doing so, your action will be saved within the Watcher Database, ready to be
+processed by the planner for creating an action plan which can then be executed
+by the Watcher Applier via its workflow engine.
+
+At the last, remember to add the action into the weights in ``watcher.conf``,
+otherwise you will get an error when the action be referenced in a strategy.
+
+
+Scheduling of an action plugin
+==============================
+
+Watcher provides a basic built-in :ref:`planner <watcher_planner_definition>`
+which is only able to process the Watcher built-in actions. Therefore, you will
+either have to use an existing third-party planner or :ref:`implement another
+planner <implement_planner_plugin>` that will be able to take into account your
+new action plugin.

+=======================================
+
+Watcher provides a plugin architecture which allows anyone to extend the
+existing functionalities by implementing third-party plugins. This process can
+be cumbersome so this documentation is there to help you get going as quickly
+as possible.
+
+
+Pre-requisites
+==============
+
+We assume that you have set up a working Watcher development environment. So if
+this not already the case, you can check out our documentation which explains
+how to set up a :ref:`development environment
+<watcher_developement_environment>`.
+
+.. _development environment:
+
+Third party project scaffolding
+===============================
+
+First off, we need to create the project structure. To do so, we can use
+`cookiecutter`_ and the `OpenStack cookiecutter`_ project scaffolder to
+generate the skeleton of our project::
+
+    $ virtualenv thirdparty
+    $ source thirdparty/bin/activate
+    $ pip install cookiecutter
+    $ cookiecutter https://github.com/openstack-dev/cookiecutter
+
+The last command will ask you for many information, and If you set
+``module_name`` and ``repo_name`` as ``thirdparty``, you should end up with a
+structure that looks like this::
+
+    $ cd thirdparty
+    $ tree .
+    .

+
+Implementing a plugin for Watcher
+=================================
+
+Now that the project skeleton has been created, you can start the
+implementation of your plugin. As of now, you can implement the following
+plugins for Watcher:
+
+- A :ref:`strategy plugin <implement_strategy_plugin>`
+- A :ref:`planner plugin <implement_planner_plugin>`
+- An :ref:`action plugin <implement_action_plugin>`
+- A :ref:`workflow engine plugin <implement_workflow_engine_plugin>`
+
+If you want to learn more on how to implement them, you can refer to their
+dedicated documentation.

+.. _implement_goal_plugin:
+
+================
+Build a new goal
+================
+
+Watcher Decision Engine has an external :ref:`goal <goal_definition>`
+plugin interface which gives anyone the ability to integrate an external
+goal which can be achieved by a :ref:`strategy <strategy_definition>`.
+
+This section gives some guidelines on how to implement and integrate custom
+goals with Watcher. If you wish to create a third-party package for your
+plugin, you can refer to our :ref:`documentation for third-party package
+creation <plugin-base_setup>`.
+
+
+Pre-requisites
+==============
+
+Before using any goal, please make sure that none of the existing goals fit
+your needs. Indeed, the underlying value of defining a goal is to be able to
+compare the efficacy of the action plans resulting from the various strategies
+satisfying the same goal. By doing so, Watcher can assist the administrator
+in his choices.
+
+
+Create a new plugin
+===================
+
+In order to create a new goal, you have to:
+
+- Extend the :py:class:`~.base.Goal` class.
+- Implement its :py:meth:`~.Goal.get_name` class method to return the
+  **unique** ID of the new goal you want to create. This unique ID should
+  be the same as the name of :ref:`the entry point you will declare later on
+  <goal_plugin_add_entrypoint>`.
+- Implement its :py:meth:`~.Goal.get_display_name` class method to
+  return the translated display name of the goal you want to create.
+  Note: Do not use a variable to return the translated string so it can be
+  automatically collected by the translation tool.
+- Implement its :py:meth:`~.Goal.get_translatable_display_name`
+  class method to return the translation key (actually the english display
+  name) of your new goal. The value return should be the same as the
+  string translated in :py:meth:`~.Goal.get_display_name`.
+- Implement its :py:meth:`~.Goal.get_efficacy_specification` method to return
+  the :ref:`efficacy specification <efficacy_specification_definition>` for
+  your goal.
+
+Here is an example showing how you can define a new ``NewGoal`` goal plugin:
+
+.. code-block:: python
+
+    # filepath: thirdparty/new.py
+    # import path: thirdparty.new
+
+    from watcher._i18n import _
+    from watcher.decision_engine.goal.efficacy import specs
+    from watcher.decision_engine.strategy.strategies import base
+
+    class NewGoal(base.Goal):
+
+        @classmethod
+        def get_name(cls):
+            return "new_goal"  # Will be the name of the entry point
+
+        @classmethod
+        def get_display_name(cls):
+            return _("New Goal")
+
+        @classmethod
+        def get_translatable_display_name(cls):
+            return "New Goal"
+
+        @classmethod
+        def get_efficacy_specification(cls):
+            return specs.UnclassifiedStrategySpecification()
+
+
+As you may have noticed, the :py:meth:`~.Goal.get_efficacy_specification`
+method returns an :py:meth:`~.UnclassifiedStrategySpecification` instance which
+is provided by Watcher. This efficacy specification is useful during the
+development process of your goal as it corresponds to an empty specification.
+If you want to learn more about what efficacy specifications are used for or to
+define your own efficacy specification, please refer to the :ref:`related
+section below <implement_efficacy_specification>`.
+
+
+Abstract Plugin Class
+=====================
+
+Here below is the abstract :py:class:`~.base.Goal` class:
+
+.. autoclass:: watcher.decision_engine.goal.base.Goal
+    :members:
+    :noindex:
+
+.. _goal_plugin_add_entrypoint:
+
+Add a new entry point
+=====================
+
+In order for the Watcher Decision Engine to load your new goal, the
+goal must be registered as a named entry point under the ``watcher_goals``
+entry point namespace of your ``setup.py`` file. If you are using pbr_, this
+entry point should be placed in your ``setup.cfg`` file.
+
+The name you give to your entry point has to be unique and should be the same
+as the value returned by the :py:meth:`~.base.Goal.get_name` class method of
+your goal.
+
+Here below is how you would proceed to register ``NewGoal`` using pbr_:
+
+.. code-block:: ini
+
+    [entry_points]
+    watcher_goals =
+        new_goal = thirdparty.new:NewGoal
+
+
+To get a better understanding on how to implement a more advanced goal,
+have a look at the :py:class:`~.ServerConsolidation` class.
+
+.. _pbr: http://docs.openstack.org/developer/pbr/
+
+.. _implement_efficacy_specification:
+
+Implement a customized efficacy specification
+=============================================
+
+What is it for?
+---------------
+
+Efficacy specifications define a set of specifications for a given goal.
+These specifications actually define a list of indicators which are to be used
+to compute a global efficacy that outlines how well a strategy performed when
+trying to achieve the goal it is associated to.
+
+The idea behind such specification is to give the administrator the possibility
+to run an audit using different strategies satisfying the same goal and be able
+to judge how they performed at a glance.
+
+
+Implementation
+--------------
+
+In order to create a new efficacy specification, you have to:
+
+- Extend the :py:class:`~.EfficacySpecification` class.
+- Implement :py:meth:`~.EfficacySpecification.get_indicators_specifications`
+  by returning a list of :py:class:`~.IndicatorSpecification` instances.
+
+  * Each :py:class:`~.IndicatorSpecification` instance should actually extend
+    the latter.
+  * Each indicator specification should have a **unique name** which should be
+    a valid Python variable name.
+  * They should implement the :py:attr:`~.EfficacySpecification.schema`
+    abstract property by returning a :py:class:`~.voluptuous.Schema` instance.
+    This schema is the contract the strategy will have to comply with when
+    setting the value associated to the indicator specification within its
+    solution (see the :ref:`architecture of Watcher
+    <sequence_diagrams_create_and_launch_audit>` for more information on
+    the audit execution workflow).
+
+- Implement the :py:meth:`~.EfficacySpecification.get_global_efficacy` method:
+  it should compute the global efficacy for the goal it achieves based on the
+  efficacy indicators you just defined.
+
+Here below is an example of an efficacy specification containing one indicator
+specification:
+
+.. code-block:: python
+
+    from watcher._i18n import _
+    from watcher.decision_engine.goal.efficacy import base as efficacy_base
+    from watcher.decision_engine.goal.efficacy import indicators
+    from watcher.decision_engine.solution import efficacy
+
+
+    class IndicatorExample(IndicatorSpecification):
+        def __init__(self):
+            super(IndicatorExample, self).__init__(
+                name="indicator_example",
+                description=_("Example of indicator specification."),
+                unit=None,
+            )
+
+        @property
+        def schema(self):
+            return voluptuous.Schema(voluptuous.Range(min=0), required=True)
+
+
+    class UnclassifiedStrategySpecification(efficacy_base.EfficacySpecification):
+
+        def get_indicators_specifications(self):
+            return [IndicatorExample()]
+
+        def get_global_efficacy(self, indicators_map):
+            return efficacy.Indicator(
+              name="global_efficacy_indicator",
+              description="Example of global efficacy indicator",
+              unit="%",
+              value=indicators_map.indicator_example % 100)
+
+
+To get a better understanding on how to implement an efficacy specification,
+have a look at :py:class:`~.ServerConsolidationSpecification`.
+
+Also, if you want to see a concrete example of an indicator specification,
+have a look at :py:class:`~.ReleasedComputeNodesCount`.

+<watcher_planner_definition>` in order to extend the initial set of planners
+Watcher provides.
+
+This section gives some guidelines on how to implement and integrate custom
+planners with Watcher.
+
+.. _Decision Engine: watcher_decision_engine_definition
+
+Creating a new plugin
+=====================
+
+First of all you have to extend the base :py:class:`~.BasePlanner` class which
+defines an abstract method that you will have to implement. The
+:py:meth:`~.BasePlanner.schedule` is the method being called by the Decision
+Engine to schedule a given solution (:py:class:`~.BaseSolution`) into an
+:ref:`action plan <action_plan_definition>` by ordering/sequencing an unordered
+set of actions contained in the proposed solution (for more details, see
+:ref:`definition of a solution <solution_definition>`).
+
+Here is an example showing how you can write a planner plugin called
+``DummyPlanner``:
+
+.. code-block:: python
+
+    # Filepath = third-party/third_party/dummy.py
+    # Import path = third_party.dummy
+    import uuid
+    from watcher.decision_engine.planner import base
+
+
+    class DummyPlanner(base.BasePlanner):
+
+        def _create_action_plan(self, context, audit_id):
+            action_plan_dict = {
+                'uuid': uuid.uuid4(),
+                'audit_id': audit_id,
+                'first_action_id': None,
+                'state': objects.action_plan.State.RECOMMENDED
+            }
+
+            new_action_plan = objects.ActionPlan(context, **action_plan_dict)
+            new_action_plan.create(context)
+            new_action_plan.save()
+            return new_action_plan
+
+        def schedule(self, context, audit_id, solution):
+            # Empty action plan
+            action_plan = self._create_action_plan(context, audit_id)
+            # todo: You need to create the workflow of actions here
+            # and attach it to the action plan
+            return action_plan
+
+This implementation is the most basic one. So if you want to have more advanced
+examples, have a look at the implementation of planners already provided by
+Watcher like :py:class:`~.DefaultPlanner`. A list with all available planner
+plugins can be found :ref:`here <watcher_planners>`.
+
+
+Define configuration parameters
+===============================
+
+At this point, you have a fully functional planner. However, in more complex
+implementation, you may want to define some configuration options so one can
+tune the planner to its needs. To do so, you can implement the
+:py:meth:`~.Loadable.get_config_opts` class method as followed:
+
+.. code-block:: python
+
+    from oslo_config import cfg
+
+    class DummyPlanner(base.BasePlanner):
+
+        # [...]
+
+        def schedule(self, context, audit_uuid, solution):
+            assert self.config.test_opt == 0
+            # [...]
+
+        def get_config_opts(self):
+            return [
+                cfg.StrOpt('test_opt', help="Demo Option.", default=0),
+                # Some more options ...
+            ]
+
+The configuration options defined within this class method will be included
+within the global ``watcher.conf`` configuration file under a section named by
+convention: ``{namespace}.{plugin_name}``. In our case, the ``watcher.conf``
+configuration would have to be modified as followed:
+
+.. code-block:: ini
+
+    [watcher_planners.dummy]
+    # Option used for testing.
+    test_opt = test_value
+
+Then, the configuration options you define within this method will then be
+injected in each instantiated object via the  ``config`` parameter of the
+:py:meth:`~.BasePlanner.__init__` method.
+
+
+Abstract Plugin Class
+=====================
+
+Here below is the abstract ``BasePlanner`` class that every single planner
+should implement:
+
+.. autoclass:: watcher.decision_engine.planner.base.BasePlanner
+    :members:
+    :special-members: __init__
+    :noindex:
+
+
+Register a new entry point
+==========================
+
+In order for the Watcher Decision Engine to load your new planner, the
+latter must be registered as a new entry point under the
+``watcher_planners`` entry point namespace of your ``setup.py`` file. If you
+are using pbr_, this entry point should be placed in your ``setup.cfg`` file.
+
+The name you give to your entry point has to be unique.
+
+Here below is how you would proceed to register ``DummyPlanner`` using pbr_:
+
+.. code-block:: ini
+
+    [entry_points]
+    watcher_planners =
+        dummy = third_party.dummy:DummyPlanner
+
+.. _pbr: http://docs.openstack.org/developer/pbr/
+
+
+Using planner plugins
+=====================
+
+The :ref:`Watcher Decision Engine <watcher_decision_engine_definition>` service
+will automatically discover any installed plugins when it is started. This
+means that if Watcher is already running when you install your plugin, you will
+have to restart the related Watcher services. If a Python package containing a
+custom plugin is installed within the same environment as Watcher, Watcher will
+automatically make that plugin available for use.
+
+At this point, Watcher will use your new planner if you referenced it in the
+``planner`` option under the ``[watcher_planner]`` section of your
+``watcher.conf`` configuration file when you started it. For example, if you
+want to use the ``dummy`` planner you just installed, you would have to
+select it as followed:
+
+.. code-block:: ini
+
+    [watcher_planner]
+    planner = dummy
+
+As you may have noticed, only a single planner implementation can be activated
+at a time, so make sure it is generic enough to support all your strategies
+and actions.

+
+=================================
+Build a new optimization strategy
+=================================
+
+Watcher Decision Engine has an external :ref:`strategy <strategy_definition>`
+plugin interface which gives anyone the ability to integrate an external
+strategy in order to make use of placement algorithms.
+
+This section gives some guidelines on how to implement and integrate custom
+strategies with Watcher. If you wish to create a third-party package for your
+plugin, you can refer to our :ref:`documentation for third-party package
+creation <plugin-base_setup>`.
+
+
+Pre-requisites
+==============
+
+Before using any strategy, you should make sure you have your Telemetry service
+configured so that it would provide you all the metrics you need to be able to
+use your strategy.
+
+
+Create a new strategy plugin
+============================
+
+In order to create a new strategy, you have to:
+
+- Extend the :py:class:`~.UnclassifiedStrategy` class
+- Implement its :py:meth:`~.BaseStrategy.get_name` class method to return the
+  **unique** ID of the new strategy you want to create. This unique ID should
+  be the same as the name of :ref:`the entry point we will declare later on
+  <strategy_plugin_add_entrypoint>`.
+- Implement its :py:meth:`~.BaseStrategy.get_display_name` class method to
+  return the translated display name of the strategy you want to create.
+  Note: Do not use a variable to return the translated string so it can be
+  automatically collected by the translation tool.
+- Implement its :py:meth:`~.BaseStrategy.get_translatable_display_name`
+  class method to return the translation key (actually the english display
+  name) of your new strategy. The value return should be the same as the
+  string translated in :py:meth:`~.BaseStrategy.get_display_name`.
+- Implement its :py:meth:`~.BaseStrategy.execute` method to return the
+  solution you computed within your strategy.
+
+Here is an example showing how you can write a plugin called ``NewStrategy``:
+
+.. code-block:: python
+
+    # filepath: thirdparty/new.py
+    # import path: thirdparty.new
+    import abc
+
+    import six
+
+    from watcher._i18n import _
+    from watcher.decision_engine.strategy.strategies import base
+
+
+    class NewStrategy(base.UnclassifiedStrategy):
+
+        def __init__(self, osc=None):
+            super(NewStrategy, self).__init__(osc)
+
+        def execute(self, original_model):
+            self.solution.add_action(action_type="nop",
+                                     input_parameters=parameters)
+            # Do some more stuff here ...
+            return self.solution
+
+        @classmethod
+        def get_name(cls):
+            return "new_strategy"
+
+        @classmethod
+        def get_display_name(cls):
+            return _("New strategy")
+
+        @classmethod
+        def get_translatable_display_name(cls):
+            return "New strategy"
+
+
+As you can see in the above example, the :py:meth:`~.BaseStrategy.execute`
+method returns a :py:class:`~.BaseSolution` instance as required. This solution
+is what wraps the abstract set of actions the strategy recommends to you. This
+solution is then processed by a :ref:`planner <watcher_planner_definition>` to
+produce an action plan which contains the sequenced flow of actions to be
+executed by the :ref:`Watcher Applier <watcher_applier_definition>`. This
+solution also contains the various :ref:`efficacy indicators
+<efficacy_indicator_definition>` alongside its computed :ref:`global efficacy
+<efficacy_definition>`.
+
+Please note that your strategy class will expect to find the same constructor
+signature as BaseStrategy to instantiate you strategy. Therefore, you should
+ensure that your ``__init__`` signature is identical to the
+:py:class:`~.BaseStrategy` one.
+
+
+Strategy efficacy
+=================
+
+As stated before, the ``NewStrategy`` class extends a class called
+:py:class:`~.UnclassifiedStrategy`. This class actually implements a set of
+abstract methods which are defined within the :py:class:`~.BaseStrategy` parent
+class.
+
+One thing this :py:class:`~.UnclassifiedStrategy` class defines is that our
+``NewStrategy`` achieves the ``unclassified`` goal. This goal is a peculiar one
+as it does not contain any indicator nor does it calculate a global efficacy.
+This proves itself to be quite useful during the development of a new strategy
+for which the goal has yet to be defined or in case a :ref:`new goal
+<implement_goal_plugin>` has yet to be implemented.
+
+
+Define Strategy Parameters
+==========================
+
+For each new added strategy, you can add parameters spec so that an operator
+can input strategy parameters when creating an audit to control the
+:py:meth:`~.BaseStrategy.execute` behavior of strategy. This is useful to
+define some threshold for your strategy, and tune them at runtime.
+
+To define parameters, just implements :py:meth:`~.BaseStrategy.get_schema` to
+return parameters spec with `jsonschema
+<http://json-schema.org/>`_ format.
+It is strongly encouraged that provide default value for each parameter, or
+else reference fails if operator specify no parameters.
+
+Here is an example showing how you can define 2 parameters for
+``DummyStrategy``:
+
+.. code-block:: python
+
+    class DummyStrategy(base.DummyBaseStrategy):
+
+        @classmethod
+        def get_schema(cls):
+            return {
+                "properties": {
+                    "para1": {
+                        "description": "number parameter example",
+                        "type": "number",
+                        "default": 3.2,
+                        "minimum": 1.0,
+                        "maximum": 10.2,
+                    },
+                    "para2": {
+                        "description": "string parameter example",
+                        "type": "string",
+                        "default": "hello",
+                    },
+                },
+            }
+
+
+You can reference parameters in :py:meth:`~.BaseStrategy.execute`:
+
+.. code-block:: python
+
+    class DummyStrategy(base.DummyBaseStrategy):
+
+        def execute(self):
+            para1 = self.input_parameters.para1
+            para2 = self.input_parameters.para2
+
+            if para1 > 5:
+                ...
+
+
+Operator can specify parameters with following commands:
+
+.. code:: bash
+
+  $ watcher audit create -a <your_audit_template> -p para1=6.0 -p para2=hi
+
+Pls. check user-guide for details.
+
+
+Abstract Plugin Class
+=====================
+
+Here below is the abstract :py:class:`~.BaseStrategy` class:
+
+.. autoclass:: watcher.decision_engine.strategy.strategies.base.BaseStrategy
+    :members:
+    :special-members: __init__
+    :noindex:
+
+.. _strategy_plugin_add_entrypoint:
+
+Add a new entry point
+=====================
+
+In order for the Watcher Decision Engine to load your new strategy, the
+strategy must be registered as a named entry point under the
+``watcher_strategies`` entry point of your ``setup.py`` file. If you are using
+pbr_, this entry point should be placed in your ``setup.cfg`` file.
+
+The name you give to your entry point has to be unique and should be the same
+as the value returned by the :py:meth:`~.BaseStrategy.get_name` class method of
+your strategy.
+
+Here below is how you would proceed to register ``NewStrategy`` using pbr_:
+
+.. code-block:: ini
+
+    [entry_points]
+    watcher_strategies =
+        new_strategy = thirdparty.new:NewStrategy
+
+
+To get a better understanding on how to implement a more advanced strategy,
+have a look at the :py:class:`~.BasicConsolidation` class.
+
+.. _pbr: http://docs.openstack.org/developer/pbr/
+
+Using strategy plugins
+======================
+
+The Watcher Decision Engine service will automatically discover any installed
+plugins when it is restarted. If a Python package containing a custom plugin is
+installed within the same environment as Watcher, Watcher will automatically
+make that plugin available for use.
+
+At this point, Watcher will scan and register inside the :ref:`Watcher Database
+<watcher_database_definition>` all the strategies (alongside the goals they
+should satisfy) you implemented upon restarting the :ref:`Watcher Decision
+Engine <watcher_decision_engine_definition>`.
+
+You should take care when installing strategy plugins. By their very nature,
+there are no guarantees that utilizing them as is will be supported, as
+they may require a set of metrics which is not yet available within the
+Telemetry service. In such a case, please do make sure that you first
+check/configure the latter so your new strategy can be fully functional.
+
+Querying metrics
+----------------
+
+A large set of metrics, generated by OpenStack modules, can be used in your
+strategy implementation. To collect these metrics, Watcher provides a
+`Helper`_ to the Ceilometer API, which makes this API reusable and easier
+to used.
+
+If you want to use your own metrics database backend, please refer to the
+`Ceilometer developer guide`_. Indeed, Ceilometer's pluggable model allows
+for various types of backends.  A list of the available backends is located
+here_. The Ceilosca project is a good example of how to create your own
+pluggable backend.
+
+Finally, if your strategy requires new metrics not covered by Ceilometer, you
+can add them through a Ceilometer `plugin`_.
+
+.. _`Helper`: https://github.com/openstack/watcher/blob/master/watcher/metrics_engine/cluster_history/ceilometer.py#L31
+.. _`Ceilometer developer guide`: http://docs.openstack.org/developer/ceilometer/architecture.html#storing-the-data
+.. _`here`: http://docs.openstack.org/developer/ceilometer/install/dbreco.html#choosing-a-database-backend
+.. _`plugin`: http://docs.openstack.org/developer/ceilometer/plugins.html
+.. _`Ceilosca`: https://github.com/openstack/monasca-ceilometer/blob/master/ceilosca/ceilometer/storage/impl_monasca.py
+
+
+Read usage metrics using the Python binding
+-------------------------------------------
+
+You can find the information about the Ceilometer Python binding on the
+OpenStack `ceilometer client python API documentation
+<http://docs.openstack.org/developer/python-ceilometerclient/api.html>`_
+
+To facilitate the process, Watcher provides the ``osc`` attribute to every
+strategy which includes clients to major OpenStack services, including
+Ceilometer. So to access it within your strategy, you can do the following:
+
+.. code-block:: py
+
+    # Within your strategy "execute()"
+    cclient = self.osc.ceilometer
+    # TODO: Do something here
+
+Using that you can now query the values for that specific metric:
+
+.. code-block:: py
+
+    query = None  # e.g. [{'field': 'foo', 'op': 'le', 'value': 34},]
+    value_cpu = cclient.samples.list(
+        meter_name='cpu_util',
+        limit=10, q=query)
+
+
+Read usage metrics using the Watcher Cluster History Helper
+-----------------------------------------------------------
+
+Here below is the abstract ``BaseClusterHistory`` class of the Helper.
+
+.. autoclass:: watcher.metrics_engine.cluster_history.base.BaseClusterHistory
+    :members:
+    :noindex:
+
+
+The following code snippet shows how to create a Cluster History class:
+
+.. code-block:: py
+
+    from watcher.metrics_engine.cluster_history import ceilometer as ceil
+
+    query_history  = ceil.CeilometerClusterHistory()
+
+Using that you can now query the values for that specific metric:
+
+.. code-block:: py
+
+    query_history.statistic_aggregation(resource_id=hypervisor.uuid,
+                                  meter_name='compute.node.cpu.percent',
+                                  period="7200",
+                                  aggregate='avg'
+                                  )

-Querying metrics
-~~~~~~~~~~~~~~~~
-
-The metrics available depend on the hypervisors that OpenStack manages on
-the specific implementation. You can find the metrics available per hypervisor
-and OpenStack release on the OpenStack site.
-
-There are different possible ways to obtain usage metrics in Watcher, you can
-use the default Ceilometer API or our Helper.
-The Helper attempted to make the Ceilometer API more reusable and easy to use.
-
-Read usage metrics using the Python binding
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-You can find the information about the Ceilometer Python binding on the
-OpenStack `ceilometer client python API documentation
-<http://docs.openstack.org/developer/python-ceilometerclient/api.html>`_
-
-The first step is to authenticate against the Ceilometer service
-(assuming that you already imported the Ceilometer client for Python)
-with this call:
-
-.. code-block:: py
-
- cclient = ceilometerclient.client.get_client(VERSION, os_username=USERNAME,
-  os_password=PASSWORD, os_tenant_name=PROJECT_NAME, os_auth_url=AUTH_URL)
-
-Using that you can now query the values for that specific metric:
-
-.. code-block:: py
-
- value_cpu = cclient.samples.list(meter_name='cpu_util', limit=10, q=query)
-

-
-Here below is the abstract ``BaseClusterHistory`` class of the Helper.
-
-.. automodule:: watcher.metrics_engine.cluster_history.api
-    :noindex:
-
-.. autoclass:: BaseClusterHistory
-    :members:
-
-
-The following snippet code shows how to create a Cluster History class:
-
-.. code-block:: py
-
-    query_history  = CeilometerClusterHistory()
-
-Using that you can now query the values for that specific metric:
-
-.. code-block:: py
-
-    query_history.statistic_aggregation(resource_id=hypervisor.uuid,
-                                  meter_name='compute.node.cpu.percent',
-                                  period="7200",
-                                  aggregate='avg'
-                                  )

+
+Unit tests
+==========
+
+All unit tests should be run using `tox`_. To run the same unit tests that are
+executing onto `Gerrit`_ which includes ``py34``, ``py27`` and ``pep8``, you
+can issue the following command::
+
+    $ workon watcher
+    (watcher) $ pip install tox
+    (watcher) $ cd watcher
+    (watcher) $ tox
+
+If you want to only run one of the aforementioned, you can then issue one of
+the following::
+
+    $ workon watcher
+    (watcher) $ tox -e py34
+    (watcher) $ tox -e py27
+    (watcher) $ tox -e pep8
+
+.. _tox: https://tox.readthedocs.org/
+.. _Gerrit: http://review.openstack.org/
+
+You may pass options to the test programs using positional arguments. To run a
+specific unit test, you can pass extra options to `os-testr`_ after putting
+the ``--`` separator. So using the ``-r`` option followed by a regex string,
+you can run the desired test::
+
+    $ workon watcher
+    (watcher) $ tox -e py27 -- -r watcher.tests.api
+
+.. _os-testr: http://docs.openstack.org/developer/os-testr/
+
+When you're done, deactivate the virtualenv::
+
+    $ deactivate
+
+.. include:: ../../../watcher_tempest_plugin/README.rst

+
+.. _administrator_definition:
+
+Administrator
+=============
+
+The :ref:`Administrator <administrator_definition>` is any user who has admin
+access on the OpenStack cluster. This user is allowed to create new projects
+for tenants, create new users and assign roles to each user.
+
+The :ref:`Administrator <administrator_definition>` usually has remote access
+to any host of the cluster in order to change the configuration and restart any
+OpenStack service, including Watcher.
+
+In the context of Watcher, the :ref:`Administrator <administrator_definition>`
+is a role for users which allows them to run any Watcher commands, such as:
+
+-  Create/Delete an :ref:`Audit Template <audit_template_definition>`
+-  Launch an :ref:`Audit <audit_definition>`
+-  Get the :ref:`Action Plan <action_plan_definition>`
+-  Launch a recommended :ref:`Action Plan <action_plan_definition>` manually
+-  Archive previous :ref:`Audits <audit_definition>` and
+   :ref:`Action Plans <action_plan_definition>`
+
+
+The :ref:`Administrator <administrator_definition>` is also allowed to modify
+any Watcher configuration files and to restart Watcher services.

+
+.. _cluster_definition:
+
+Cluster
+=======
+
+A :ref:`Cluster <cluster_definition>` is a set of physical machines which
+provide compute, storage and networking resources and are managed by the same
+OpenStack Controller node.
+A :ref:`Cluster <cluster_definition>` represents a set of resources that a
+cloud provider is able to offer to his/her
+:ref:`customers <customer_definition>`.
+
+A data center may contain several clusters.
+
+The :ref:`Cluster <cluster_definition>` may be divided in one or several
+:ref:`Availability Zone(s) <availability_zone_definition>`.
+
+.. _cluster_data_model_definition:
+
+Cluster Data Model
+==================
+
+.. watcher-term:: watcher.metrics_engine.cluster_model_collector.base
+
+.. _cluster_history_definition:
+
+Cluster History
+===============
+
+.. watcher-term:: watcher.metrics_engine.cluster_history.base
+
+.. _controller_node_definition:
+
+Controller Node
+===============
+
+A controller node is a machine that typically runs the following core OpenStack
+services:
+
+-  Keystone: for identity and service management
+-  Cinder scheduler: for volumes management
+-  Glance controller: for image management
+-  Neutron controller: for network management
+-  Nova controller: for global compute resources management with services
+   such as nova-scheduler, nova-conductor and nova-network.
+
+In many configurations, Watcher will reside on a controller node even if it
+can potentially be hosted on a dedicated machine.
+
+.. _compute_node_definition:
+
+Compute node
+============
+
+Please, read `the official OpenStack definition of a Compute Node
+<http://docs.openstack.org/openstack-ops/content/compute_nodes.html>`_.
+
+.. _customer_definition:
+
+Customer
+========
+
+A :ref:`Customer <customer_definition>` is the person or company which
+subscribes to the cloud provider offering. A customer may have several
+:ref:`Project(s) <project_definition>`
+hosted on the same :ref:`Cluster <cluster_definition>` or dispatched on
+different clusters.
+
+In the private cloud context, the :ref:`Customers <customer_definition>` are
+different groups within the same organization (different departments, project
+teams, branch offices and so on). Cloud infrastructure includes the ability to
+precisely track each customer's service usage so that it can be charged back to
+them, or at least reported to them.
+
+.. _goal_definition:
+
+Goal
+====
+
+.. watcher-term:: watcher.api.controllers.v1.goal

+Please, read `the official OpenStack definition of a Host Aggregate <http://docs.openstack.org/developer/nova/aggregates.html>`_.
+
+.. _instance_definition:
+
+Instance
+========
+
+A running virtual machine, or a virtual machine in a known state such as
+suspended, that can be used like a hardware server.
+
+.. _managed_resource_definition:
+
+Managed resource
+================
+
+A :ref:`Managed resource <managed_resource_definition>` is one instance of
+:ref:`Managed resource type <managed_resource_type_definition>` in a topology
+with particular properties and dependencies on other
+:ref:`Managed resources <managed_resource_definition>` (relationships).
+
+For example, a :ref:`Managed resource <managed_resource_definition>` can be one
+virtual machine (i.e., an :ref:`instance <instance_definition>`) hosted on a
+:ref:`compute node <compute_node_definition>` and connected to another virtual
+machine through a network link (represented also as a
+:ref:`Managed resource <managed_resource_definition>` in the
+:ref:`Cluster Data Model <cluster_data_model_definition>`).
+
+.. _managed_resource_type_definition:
+
+Managed resource type
+=====================
+
+A :ref:`Managed resource type <managed_resource_definition>` is a type of
+hardware or software element of the :ref:`Cluster <cluster_definition>` that
+the Watcher system can act on.
+
+Here are some examples of
+:ref:`Managed resource types <managed_resource_definition>`:
+
+-  `Nova Host Aggregates <http://docs.openstack.org/developer/heat/template_guide/openstack.html#OS::Nova::HostAggregate>`_
+-  `Nova Servers <http://docs.openstack.org/developer/heat/template_guide/openstack.html#OS::Nova::Server>`_
+-  `Cinder Volumes <http://docs.openstack.org/developer/heat/template_guide/openstack.html#OS::Cinder::Volume>`_
+-  `Neutron Routers <http://docs.openstack.org/developer/heat/template_guide/openstack.html#OS::Neutron::Router>`_
+-  `Neutron Networks <http://docs.openstack.org/developer/heat/template_guide/openstack.html#OS::Neutron::Net>`_
+-  `Neutron load-balancers <http://docs.openstack.org/developer/heat/template_guide/openstack.html#OS::Neutron::LoadBalancer>`_
+-  `Sahara Hadoop Cluster <http://docs.openstack.org/developer/heat/template_guide/openstack.html#OS::Sahara::Cluster>`_
+-  ...
+
+It can be any of the `the official list of available resource types defined in
+OpenStack for HEAT
+<http://docs.openstack.org/developer/heat/template_guide/openstack.html>`_.
+
+.. _efficacy_indicator_definition:
+
+Efficacy Indicator
+==================
+
+.. watcher-term:: watcher.api.controllers.v1.efficacy_indicator
+
+.. _efficacy_specification_definition:
+
+Efficacy Specification
+======================
+
+.. watcher-term:: watcher.decision_engine.goal.efficacy.base
+
+.. _efficacy_definition:
+
+Optimization Efficacy
+=====================
+
+The :ref:`Optimization Efficacy <efficacy_definition>` is the objective
+measure of how much of the :ref:`Goal <goal_definition>` has been achieved in
+respect with constraints and :ref:`SLAs <sla_definition>` defined by the
+:ref:`Customer <customer_definition>`.
+
+The way efficacy is evaluated will depend on the :ref:`Goal <goal_definition>`
+to achieve.
+
+Of course, the efficacy will be relevant only as long as the
+:ref:`Action Plan <action_plan_definition>` is relevant
+(i.e., the current state of the :ref:`Cluster <cluster_definition>`
+has not changed in a way that a new :ref:`Audit <audit_definition>` would need
+to be launched).
+
+For example, if the :ref:`Goal <goal_definition>` is to lower the energy
+consumption, the :ref:`Efficacy <efficacy_definition>` will be computed
+using several :ref:`efficacy indicators <efficacy_indicator_definition>`
+(KPIs):
+
+-  the percentage of energy gain (which must be the highest possible)
+-  the number of :ref:`SLA violations <sla_violation_definition>`
+   (which must be the lowest possible)
+-  the number of virtual machine migrations (which must be the lowest possible)
+
+All those indicators are computed within a given timeframe, which is the
+time taken to execute the whole :ref:`Action Plan <action_plan_definition>`.
+
+The efficacy also enables the :ref:`Administrator <administrator_definition>`
+to objectively compare different :ref:`Strategies <strategy_definition>` for
+the same goal and same workload of the :ref:`Cluster <cluster_definition>`.
+
+.. _project_definition:
+
+Project
+=======
+
+:ref:`Projects <project_definition>` represent the base unit of “ownership”
+in OpenStack, in that all :ref:`resources <managed_resource_definition>` in
+OpenStack should be owned by a specific :ref:`project <project_definition>`.
+In OpenStack Identity, a :ref:`project <project_definition>` must be owned by a
+specific domain.
+
+Please, read `the official OpenStack definition of a Project
+<http://docs.openstack.org/glossary/content/glossary.html>`_.
+
+
+.. _sla_definition:
+
+SLA
+===
+
+:ref:`SLA <sla_definition>` means Service Level Agreement.
+
+The resources are negotiated between the :ref:`Customer <customer_definition>`
+and the Cloud Provider in a contract.
+
+Most of the time, this contract is composed of two documents:
+
+-  :ref:`SLA <sla_definition>` : Service Level Agreement
+-  :ref:`SLO <slo_definition>` : Service Level Objectives
+
+Note that the :ref:`SLA <sla_definition>` is more general than the
+:ref:`SLO <slo_definition>` in the sense that the former specifies what service
+is to be provided, how it is supported, times, locations, costs, performance,
+and responsibilities of the parties involved while the
+:ref:`SLO <slo_definition>` focuses on more measurable characteristics such as
+availability, throughput, frequency, response time or quality.
+
+You can also read `the Wikipedia page for SLA <https://en.wikipedia.org/wiki/Service-level_agreement>`_
+which provides a good definition.
+
+.. _sla_violation_definition:
+
+SLA violation
+=============
+
+A :ref:`SLA violation <sla_violation_definition>` happens when a
+:ref:`SLA <sla_definition>` defined with a given
+:ref:`Customer <customer_definition>` could not be respected by the
+cloud provider within the timeframe defined by the official contract document.
+
+.. _slo_definition:
+
+SLO
+===
+
+A Service Level Objective (SLO) is a key element of a
+:ref:`SLA <sla_definition>` between a service provider and a
+:ref:`Customer <customer_definition>`. SLOs are agreed as a means of measuring
+the performance of the Service Provider and are outlined as a way of avoiding
+disputes between the two parties based on misunderstanding.
+
+You can also read `the Wikipedia page for SLO <https://en.wikipedia.org/wiki/Service_level_objective>`_
+which provides a good definition.

+
+Strategy

+.. watcher-term:: watcher.applier.base
+
+.. _watcher_database_definition:
+
+Watcher Database
+================
+
+This database stores all the Watcher domain objects which can be requested
+by the Watcher API or the Watcher CLI:
+
+-  Audit templates
+-  Audits
+-  Action plans
+-  Actions
+-  Goals
+
+The Watcher domain being here "*optimization of some resources provided by an
+OpenStack system*".
+
+See :doc:`architecture` for more details on this component.

+OpenStack Watcher provides a flexible and scalable resource optimization
+service for multi-tenant OpenStack-based clouds.
+Watcher provides a complete optimization loop—including everything from a
+metrics receiver, complex event processor and profiler, optimization processor
+and an action plan applier. This provides a robust framework to realize a wide
+range of cloud optimization goals, including the reduction of data center
+operating costs, increased system performance via intelligent virtual machine
+migration, increased energy efficiency—and more!
+
+Watcher project consists of several source code repositories:
+
+* `watcher`_ - is the main repository. It contains code for Watcher API server,
+  Watcher Decision Engine and Watcher Applier.
+* `python-watcherclient`_ - Client library and CLI client for Watcher.
+* `watcher-dashboard`_ - Watcher Horizon plugin.
+
+The documentation provided here is continually kept up-to-date based
 on the latest code, and may not represent the state of the project at any
 specific prior release.

+An :ref:`Action <action_definition>` is what enables Watcher to transform the
+current state of a :ref:`Cluster <cluster_definition>` after an
+:ref:`Audit <audit_definition>`.
+
+An :ref:`Action <action_definition>` is an atomic task which changes the
+current state of a target :ref:`Managed resource <managed_resource_definition>`
+of the OpenStack :ref:`Cluster <cluster_definition>` such as:
+
+-  Live migration of an instance from one compute node to another compute
+   node with Nova
+-  Changing the power level of a compute node (ACPI level, ...)
+-  Changing the current state of an hypervisor (enable or disable) with Nova
+
+In most cases, an :ref:`Action <action_definition>` triggers some concrete
+commands on an existing OpenStack module (Nova, Neutron, Cinder, Ironic, etc.).
+
+An :ref:`Action <action_definition>` has a life-cycle and its current state may
+be one of the following:
+
+-  **PENDING** : the :ref:`Action <action_definition>` has not been executed
+   yet by the :ref:`Watcher Applier <watcher_applier_definition>`
+-  **ONGOING** : the :ref:`Action <action_definition>` is currently being
+   processed by the :ref:`Watcher Applier <watcher_applier_definition>`
+-  **SUCCEEDED** : the :ref:`Action <action_definition>` has been executed
+   successfully
+-  **FAILED** : an error occured while trying to execute the
+   :ref:`Action <action_definition>`
+-  **DELETED** : the :ref:`Action <action_definition>` is still stored in the
+   :ref:`Watcher database <watcher_database_definition>` but is not returned
+   any more through the Watcher APIs.
+-  **CANCELLED** : the :ref:`Action <action_definition>` was in **PENDING** or
+   **ONGOING** state and was cancelled by the
+   :ref:`Administrator <administrator_definition>`
+
+:ref:`Some default implementations are provided <watcher_planners>`, but it is
+possible to :ref:`develop new implementations <implement_action_plugin>` which
+are dynamically loaded by Watcher at launch time.

+An efficacy indicator is a single value that gives an indication on how the
+:ref:`solution <solution_definition>` produced by a given :ref:`strategy
+<strategy_definition>` performed. These efficacy indicators are specific to a
+given :ref:`goal <goal_definition>` and are usually used to compute the
+:ref:`gobal efficacy <efficacy_definition>` of the resulting :ref:`action plan
+<action_plan_definition>`.
+
+In Watcher, these efficacy indicators are specified alongside the goal they
+relate to. When a strategy (which always relates to a goal) is executed, it
+produces a solution containing the efficacy indicators specified by the goal.
+This solution, which has been translated by the :ref:`Watcher Planner
+<watcher_planner_definition>` into an action plan, will see its indicators and
+global efficacy stored and would now be accessible through the :ref:`Watcher
+API <archi_watcher_api_definition>`.

-# Watcher Actions Applier
-
-This component is in charge of executing the plan of actions built by the Watcher Actions Planner.
-
-For each action of the workflow, this component may call directly the component responsible for this kind of action (Example : Nova API for an instance migration) or via some publish/subscribe pattern on the message bus.
-
-It notifies continuously of the current progress of the Action Plan (and atomic Actions), sending status messages on the bus. Those events may be used by the CEP to trigger new actions.
-
-This component is also connected to the Watcher MySQL database in order to:
-* get the description of the action plan to execute
-* persist its current state so that if it is restarted, it can restore each Action plan context and restart from the last known safe point of each ongoing workflow.
