-API versions
-============
-
-In order to bring new features to users over time, the Watcher API
-supports versioning. There are two kinds of versions in Watcher.
-
-- ''major versions'', which have dedicated URLs.
-- ''microversions'', which can be requested using the
-  ``OpenStack-API-Version`` header.
-
-.. note:: The maximum microversion depends on release.
-  Please reference:
-  `API Microversion History
-  <https://docs.openstack.org/watcher/latest/contributor/api_microversion_history.html>`__
-  for API microversion history details.
-
-The Version API resource works differently from other API resources as they *do not*
-require authentication.
-
-If Watcher receives a request with unsupported version, it responds with a 406 Not Acceptable,
-along with the -Min- and -Max- headers that it can support.
-
-List API versions
-=================
-
-.. rest_method::  GET /
-
-This fetches all the information about all known major API versions in the
-deployment. Links to more specific information will be provided for each major
-API version, as well as information about supported min and max microversions.

-Introduction
-************
-
-Modern processors typically contain multiple cores all capable of executing
-instructions in parallel. Ensuring applications can fully utilize modern
-underlying hardware requires developing with these concepts in mind. The
-OpenStack foundation maintains a number of libraries to facilitate this
-utilization, combined with constructs like CPython's GIL_ the proper use of
-these concepts becomes more straightforward compared to other programming
-languages.
-
-The primary libraries maintained by OpenStack to facilitate concurrency are
-futurist_ and taskflow_. Here futurist is a more straightforward and
-lightweight library while taskflow is more advanced supporting features like
-rollback mechanisms. Within Watcher both libraries are used to facilitate
-concurrency.

-
-Threadpool
-**********
-
-A threadpool is a collection of one or more threads typically called *workers*
-to which tasks can be submitted. These submitted tasks will be scheduled by a
-threadpool and subsequently executed. In the case of Python tasks typically are
-bounded or unbounded methods while other programming languages like Java
-require implementing an interface.
-
-The order and amount of concurrency with which these tasks are executed is up
-to the threadpool to decide. Some libraries like taskflow allow for either
-strong or loose ordering of tasks while others like futurist might only support
-loose ordering. Taskflow supports building tree-based hierarchies of dependent
-tasks for example.
-
-Upon submission of a task to a threadpool a so called future_ is returned.
-These objects allow to determine information about the task such as if it is
-currently being executed or if it has finished execution. When the task has
-finished execution the future can also be used to retrieve what was returned by
-the method.
-
-Some libraries like futurist provide synchronization primitives for collections
-of futures such as wait_for_any_. The following sections will cover different
-types of concurrency used in various services of Watcher.

-Decision engine concurrency
-***************************
-
-The concurrency in the decision engine is governed by two independent
-threadpools. Both of these threadpools are GreenThreadPoolExecutor_ from the
-futurist_ library. One of these is used automatically and most contributors
-will not interact with it while developing new features. The other threadpool
-can frequently be used while developing new features or updating existing ones.
-It is known as the DecisionEngineThreadpool and allows to achieve performance
-improvements in network or I/O bound operations.
-
-.. _GreenThreadPoolExecutor: https://docs.openstack.org/futurist/latest/reference/index.html#executors
-
-AuditEndpoint
-#############
-
-The first threadpool is used to allow multiple audits to be run in parallel.
-In practice, however, only one audit can be run in parallel. This is due to
-the data model used by audits being a singleton. To prevent audits destroying
-each others data model one must wait for the other to complete before being
-allowed to access this data model. A performance improvement could be achieved
-by being more intelligent in the use, caching and construction of these
-data models.
-
-DecisionEngineThreadPool
-########################
-
-The second threadpool is used for generic tasks, typically networking and I/O
-could benefit the most of this threadpool. Upon execution of an audit this
-threadpool can be utilized to retrieve information from the Nova compute
-service for instance. This second threadpool is a singleton and is shared
-amongst concurrently running audits as a result the amount of workers is static
-and independent from the amount of workers in the first threadpool. The use of
-the :class:`~.DecisionEngineThreadpool` while building the Nova compute data
-model is demonstrated to show how it can effectively be used.
-
-In the following example a reference to the
-:class:`~.DecisionEngineThreadpool` is stored in ``self.executor``. Here two
-tasks are submitted one with function ``self._collect_aggregates`` and the
-other function ``self._collect_zones``. With both ``self.executor.submit``
-calls subsequent arguments are passed to the function. All subsequent arguments
-are passed to the function being submitted as task following the common
-``(fn, *args, **kwargs)`` signature. One of the original signatures would be
-``def _collect_aggregates(host_aggregates, compute_nodes)`` for example.
-
-.. code-block:: python
-
-    zone_aggregate_futures = {
-        self.executor.submit(
-            self._collect_aggregates, host_aggregates, compute_nodes),
-        self.executor.submit(
-            self._collect_zones, availability_zones, compute_nodes)
-    }
-    waiters.wait_for_all(zone_aggregate_futures)
-
-The last statement of the example above waits on all futures to complete.
-Similarly, ``waiters.wait_for_any`` will wait for any future of the specified
-collection to complete. To simplify the usage of ``wait_for_any`` the
-:class:`~.DecisiongEngineThreadpool` defines a ``do_while_futures`` method.
-This method will iterate in a do_while loop over a collection of futures until
-all of them have completed. The advantage of ``do_while_futures`` is that it
-allows to immediately call a method as soon as a future finishes. The arguments
-for this callback method can be supplied when calling ``do_while_futures``,
-however, the first argument to the callback is always the future itself! If
-the collection of futures can safely be modified ``do_while_futures_modify``
-can be used and should have slightly better performance. The following example
-will show how ``do_while_futures`` is used in the decision engine.
-
-.. code-block:: python
-
-    # For every compute node from compute_nodes submit a task to gather the node it's information.
-    # List comprehension is used to store all the futures of the submitted tasks in node_futures.
-    node_futures = [self.executor.submit(
-        self.nova_helper.get_compute_node_by_name,
-        node, servers=True, detailed=True)
-        for node in compute_nodes]
-    LOG.debug("submitted {0} jobs".format(len(compute_nodes)))
-
-    future_instances = []
-    # do_while iterate over node_futures and upon completion of a future call
-    # self._compute_node_future with the future and future_instances as arguments.
-    self.executor.do_while_futures_modify(
-        node_futures, self._compute_node_future, future_instances)
-
-    # Wait for all instance jobs to finish
-    waiters.wait_for_all(future_instances)
-
-Finally, let's demonstrate how powerful this ``do_while_futures`` can be by
-showing what the ``compute_node_future`` callback does. First, it retrieves the
-result from the future and adds the compute node to the data model. Afterwards,
-it checks if the compute node has any associated instances and if so it submits
-an additional task to the :class:`~.DecisionEngineThreadpool`. The future is
-appended to the ``future_instances`` so ``waiters.wait_for_all`` can be called
-on this list. This is important as otherwise the building of the data model
-might return before all tasks for instances have finished.
-
-.. code-block:: python
-
-    # Get the result from the future.
-    node_info = future.result()[0]
-
-    # Filter out baremetal nodes.
-    if node_info.hypervisor_type == 'ironic':
-        LOG.debug("filtering out baremetal node: %s", node_info)
-        return
-
-    # Add the compute node to the data model.
-    self.add_compute_node(node_info)
-    # Get the instances from the compute node.
-    instances = getattr(node_info, "servers", None)
-    # Do not submit job if there are no instances on compute node.
-    if instances is None:
-        LOG.info("No instances on compute_node: {0}".format(node_info))
-        return
-    # Submit a job to retrieve detailed information about the instances.
-    future_instances.append(
-        self.executor.submit(
-            self.add_instance_node, node_info, instances)
-    )
-
-Without ``do_while_futures`` an additional ``waiters.wait_for_all`` would be
-required in between the compute node tasks and the instance tasks. This would
-cause the progress of the decision engine to stall as less and less tasks
-remain active before the instance tasks could be submitted. This demonstrates
-how ``do_while_futures`` can be used to achieve more constant utilization of
-the underlying hardware.
-
-Applier concurrency
-*******************
-
-The applier does not use the futurist_ GreenThreadPoolExecutor_ directly but
-instead uses taskflow_. However, taskflow still utilizes a greenthreadpool.
-This threadpool is initialized in the workflow engine called
-:class:`~.DefaultWorkFlowEngine`. Currently Watcher supports one workflow
-engine but the base class allows contributors to develop other workflow engines
-as well. In taskflow tasks are created using different types of flows such as a
-linear, unordered or a graph flow. The linear and graph flow allow for strong
-ordering between individual tasks and it is for this reason that the workflow
-engine utilizes a graph flow. The creation of tasks, subsequently linking them
-into a graph like structure and submitting them is shown below.
-
-.. code-block:: python
-
-    self.execution_rule = self.get_execution_rule(actions)
-    flow = gf.Flow("watcher_flow")
-    actions_uuid = {}
-    for a in actions:
-        task = TaskFlowActionContainer(a, self)
-        flow.add(task)
-        actions_uuid[a.uuid] = task
-
-    for a in actions:

-==================
-Grafana datasource
-==================
-
-Synopsis
---------
-
-Grafana can interface with many different types of storage backends that
-Grafana calls datasources_. Since the term datasources causes significant
-confusion by overlapping definitions used in Watcher these **datasources are
-called projects instead**. Some examples of supported projects are InfluxDB
-or Elasticsearch while others might be more familiar such as Monasca or
-Gnocchi. The Grafana datasource provides the functionality to retrieve metrics
-from Grafana for different projects. This functionality is achieved by using
-the proxy interface exposed in Grafana to communicate with Grafana projects
-directly.
-
-Background
-**********
-
-Since queries to retrieve metrics from Grafana are proxied to the project the
-format of these queries will change significantly depending on the type of
-project. The structure of the projects themselves will also change
-significantly as they are structured by users and administrators. For instance,
-some developers might decide to store metrics about compute_nodes in MySQL and
-use the UUID as primary key while others use InfluxDB and use the hostname as
-primary key. Furthermore, datasources in Watcher should return metrics in
-specific units strictly defined in the baseclass_ depending on how the units
-are stored in the projects they might require conversion before being returned.
-The flexible configuration parameters of the Grafana datasource allow to
-specify exactly how the deployment is configured and this will enable to
-correct retrieval of metrics and with the correct units.
-
-.. _datasources: https://grafana.com/plugins?type=datasource
-.. _baseclass: https://github.com/openstack/watcher/blob/584eeefdc8/watcher/datasources/base.py
-
-Requirements
-------------
-
-The use of the Grafana datasource requires a reachable Grafana endpoint and an
-authentication token for access to the desired projects. The projects behind
-Grafana will need to contain the metrics for compute_nodes_ or instances_ and
-these need to be identifiable by an attribute of the Watcher datamodel_ for
-instance hostname or UUID.

-.. _datamodel: https://opendev.org/openstack/watcher/src/branch/master/watcher/decision_engine/model/element
-
-Limitations
-***********
-
-* Only the InfluxDB project is currently supported [#f1]_.
-* All metrics must be retrieved from the same Grafana endpoint (same URL).
-* All metrics must be retrieved with the same authentication token.
-
-.. [#f1] A base class for projects is available_ and easily extensible.

-
-Configuration
--------------
-
-Several steps are required in order to use the Grafana datasource, Most steps
-are related configuring Watcher to match the deployed Grafana setup such as
-queries proxied to the project or the type of project for any given metric.
-Most of the configuration can either be supplied via the traditional
-configuration file or in a `special yaml`_ file.
-
-.. _special yaml: https://specs.openstack.org/openstack/watcher-specs/specs/train/approved/file-based-metricmap.html
-
-token
-*****
-
-First step is to generate an access token with access to the required projects.
-This can be done from the api_ or from the web interface_. Tokens generated
-from the web interface will have the same access to projects as the user that
-created them while using the cli allows to generate a key for a specific
-role.The token will only be displayed once so store it well. This token will go
-into the configuration file later and this parameter can not be placed in the
-yaml.
-
-.. _api: https://grafana.com/docs/http_api/auth/#create-api-key
-.. _interface: https://grafana.com/docs/http_api/auth/#create-api-token
-
-base_url
-********
-
-Next step is supplying the base url of the Grafana endpoint. The base url
-parameter will need to specify the type of http protocol and the use of
-plain text http is strongly discouraged due to the transmission of the access
-token. Additionally the path to the proxy interface needs to be supplied as
-well in case Grafana is placed in a sub directory of the web server. An example
-would be: `https://mygrafana.org/api/datasource/proxy/` were
-`/api/datasource/proxy` is the default path without any subdirectories.
-Likewise, this parameter can not be placed in the yaml.
-
-To prevent many errors from occurring and potentially filing the logs files it
-is advised to specify the desired datasource in the configuration as it would
-prevent the datasource manager from having to iterate and try possible
-datasources with the launch of each audit. To do this specify `datasources` in
-the `[watcher_datasources]` group.
-
-The current configuration that is required to be placed in the traditional
-configuration file would look like the following:
-
-.. code-block:: shell
-
-    [grafana_client]
-    token = 0JLbF0oB4R3Q2Fl337Gh4Df5VN12D3adBE3f==
-    base_url = https://mygranfa.org/api/datasource/proxy
-
-    [watcher_datasources]
-    datasources = grafana
-
-metric parameters
-*****************
-
-The last five remaining configuration parameters can all be placed both in the
-traditional configuration file or in the yaml, however, it is not advised to
-mix and match but in the case it does occur the yaml would override the
-settings from the traditional configuration file. All five of these parameters
-are dictionaries mapping specific metrics to a configuration parameter. For
-instance the `project_id_map` will specify the specific project id in Grafana
-to be used. The parameters are named as follow:
-
-* project_id_map
-* database_map
-* translator_map
-* attribute_map
-* query_map
-
-These five parameters are named differently if configured using the yaml
-configuration file. The parameters are named as follows and are in
-identical order as to the list of the traditional configuration file:
-
-* project
-* db
-* translator
-* attribute
-* query
-
-When specified in the yaml the parameters are no longer dictionaries instead
-each parameter needs to be defined per metric as sub-parameters. Examples of
-these parameters configured for both the yaml and traditional configuration
-are described at the end of this document.
-
-project_id
-**********
-
-The project id's can only be determined by someone with the admin role in
-Grafana as that role is required to open the list of projects. The list of
-projects can be found on `/datasources` in the web interface but
-unfortunately it does not immediately display the project id. To display
-the id one can best hover the mouse over the projects and the url will show the
-project id's for example `/datasources/edit/7563`. Alternatively the entire
-list of projects can be retrieved using the `REST api`_. To easily make
-requests to the REST api a tool such as Postman can be used.
-
-.. _REST api: https://grafana.com/docs/http_api/data_source/#get-all-datasources
-
-database
-********
-
-The database is the parameter for the schema / database that is actually
-defined in the project. For instance, if the project would be based on MySQL
-this is were the name of schema used within the MySQL server would be
-specified. For many different projects it is possible to list all the databases
-currently available. Tools like Postman can be used to list all the available
-databases per project. For InfluxDB based projects this would be with the
-following path and query, however be sure to construct these request in Postman
-as the header needs to contain the authorization token:
-
-.. code-block:: shell
-
-    https://URL.DOMAIN/api/datasources/proxy/PROJECT_ID/query?q=SHOW%20DATABASES
-
-translator
-**********
-
-Each translator is for a specific type of project will have a uniquely
-identifiable name and the baseclass allows to easily support new types of
-projects such as elasticsearch or prometheus. Currently only InfluxDB based
-projects are supported as a result the only valid value for this parameter is `
-influxdb`.
-
-attribute
-*********
-
-The attribute parameter specifies which attribute to use from Watcher's
-data model in order to construct the query. The available attributes differ
-per type of object in the data model but the following table shows the
-attributes for ComputeNodes, Instances and IronicNodes.
-
-+-----------------+-----------------+--------------------+
-| ComputeNode     | Instance        | IronicNode         |

-
-Many if not all of these attributes map to attributes of the objects that are
-fetched from clients such as Nova. To see how these attributes are put into the
-data model the following source files can be analyzed for Nova_ and Ironic_.
-
-.. _Nova: https://opendev.org/openstack/watcher/src/branch/master/watcher/decision_engine/model/collector/nova.py#L304
-.. _Ironic: https://opendev.org/openstack/watcher/src/branch/master/watcher/decision_engine/model/collector/ironic.py#L85
-
-query
-*****
-
-The query is the single most important parameter it will be passed to the
-project and should return the desired metric for the specific host and return
-the value in the correct unit. The units for all available metrics are
-documented in the `datasource baseclass`_. This might mean the query specified
-in this parameter is responsible for converting the unit. The following query
-demonstrates how such a conversion could be achieved and demonstrates the
-conversion from bytes to megabytes.
-
-.. code-block:: shell
-
-    SELECT value/1000000 FROM memory...
-
-Queries will be formatted using the .format string method within Python. This
-format will currently have give attributes exposed to it labeled `{0}` to
-`{4}`. Every occurrence of these characters within the string will be replaced
-with the specific attribute.
-
-- {0} is the aggregate typically `mean`, `min`, `max` but `count` is also
-  supported.
-- {1} is the attribute as specified in the attribute parameter.
-- {2} is the period of time to aggregate data over in seconds.
-- {3} is the granularity or the interval between data points in seconds.
-- {4} is translator specific and in the case of InfluxDB it will be used for
-  retention_periods.
-
-**InfluxDB**
-
-Constructing the queries or rather anticipating how the results should look to
-be correctly interpreted by Watcher can be a challenge. The following json
-example demonstrates how what the result should look like and the query used to
-get this result.
-
-.. code-block:: json
-
-    {
-    "results": [
-        {
-            "statement_id": 0,

-                        [

-                }
-            ]
-        }
-    ]
-    }

-Example configuration
----------------------
-
-The example configurations will show both how to achieve the entire
-configuration in the config file or use a combination of the regular file and
-yaml. Using yaml to define all the parameters for each metric is recommended
-since it has better human readability and supports mutli-line option
-definitions.
-
-Configuration file
-******************
-
-**It is important to note that the line breaks shown in between assignments of
-parameters can not be used in the actual configuration and these are simply here
-for readability reasons.**

-yaml
-****
-
-When using the yaml configuration file some parameters still need to be defined
-using the regular configuration such as the path for the yaml file these
-parameters are detailed below:
-
-.. code-block:: shell
-
-    [grafana_client]
-    token = eyJrIjoiT0tTcG1pUlY2RnVKZTFVaDFsNFZXdE9ZWmNrMkZYbk==

-
-    [watcher_datasources]
-    datasources = grafana
-
-    [watcher_decision_engine]
-    metric_map_path = /etc/watcher/metric_map.yaml
-
-Using the yaml allows to more effectively define the parameters per metric with
-greater human readability due to the availability of multi line options. These
-multi line options are demonstrated in the query parameters.
-
-.. code-block:: yaml
-
-  grafana:
-    host_cpu_usage:

-
-:program:`watcher-status` is a tool that provides routines for checking the
-status of a Watcher deployment.
-
-Options
-=======
-
-The standard pattern for executing a :program:`watcher-status` command is::
-
-    watcher-status <category> <command> [<args>]
-
-Run without arguments to see a list of available command categories::
-
-    watcher-status
-
-Categories are:
-
-* ``upgrade``
-
-Detailed descriptions are below:
-
-You can also run with a category argument such as ``upgrade`` to see a list of
-all commands in that category::
-
-    watcher-status upgrade

-Audit using Aodh alarm
-======================
-
-Audit with EVENT type can be triggered by special alarm. This guide walks
-you through the steps to build an event-driven optimization solution by
-integrating Watcher with Ceilometer/Aodh.
-
-Step 1: Create an audit with EVENT type
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-The first step is to create an audit with EVENT type,
-you can create an audit template firstly:
-
-.. code-block:: bash
-
-  $ openstack optimize audittemplate create your_template_name <your_goal> \
-    --strategy <your_strategy>
-
-or create an audit directly with special goal and strategy:
-
-.. code-block:: bash
-
-  $ openstack optimize audit create --goal <your_goal> \
-    --strategy <your_strategy> --audit_type EVENT
-
-This is an example for creating an audit with dummy strategy:
-
-.. code-block:: bash
-
-  $ openstack optimize audit create --goal dummy \
-    --strategy dummy --audit_type EVENT

-
-We need to build Aodh action url using Watcher webhook API.
-For convenience we export the url into an environment variable:
-
-.. code-block:: bash
-
-  $ export AUDIT_UUID=a3326a6a-c18e-4e8e-adba-d0c61ad404c5
-  $ export ALARM_URL="trust+http://localhost/infra-optim/v1/webhooks/$AUDIT_UUID"
-
-Step 2: Create Aodh Alarm
-~~~~~~~~~~~~~~~~~~~~~~~~~
-
-Once we have the audit created, we can continue to create Aodh alarm and
-set the alarm action to Watcher webhook API. The alarm type can be event(
-i.e. ``compute.instance.create.end``) or gnocchi_resources_threshold(i.e.
-``cpu_util``), more info refer to alarm-creation_
-
-For example:
-
-.. code-block:: bash
-
-  $ openstack alarm create \
-    --type event --name instance_create \
-    --event-type "compute.instance.create.end" \
-    --enable True --repeat-actions False \
-    --alarm-action $ALARM_URL

-    Added a new config option 'action_execution_rule' which is a dict type.
-    Its key field is strategy name and the value is 'ALWAYS' or 'ANY'.
-    'ALWAYS' means the callback function returns True as usual.
-    'ANY' means the return depends on the result of previous action execution.
-    The callback returns True if previous action gets failed, and the engine
-    continues to run the next action. If previous action executes success,
-    the callback returns False then the next action will be ignored.
-    For strategies that aren't in 'action_execution_rule', the callback always
-    returns True.
-    Please add the next section in the watcher.conf file
-    if your strategy needs this feature.
-    [watcher_workflow_engines.taskflow]
-    action_execution_rule = {'your strategy name': 'ANY'}

-    Allow using file to override metric map. Override the metric map of
