Configure Ceilometer
====================
Configure Measurements
======================
The default strategy 'basic_consolidation' provided by watcher requires
Ceilometer to collect the "compute.node.cpu.*." and "cpu_util" measurements
You can configure and install Ceilometer by following the documentation below :
#. Add/Update the following lines into the /etc/nova/nova.conf configuration file:
#. http://docs.openstack.org/developer/ceilometer
#. http://docs.openstack.org/kilo/install-guide/install/apt/content/ceilometer-nova.html
The built-in strategy 'basic_consolidation' provided by watcher requires
"**compute.node.cpu.percent**" and "**cpu_util**" measurements to be collected
by Ceilometer.
The measurements available depend on the hypervisors that OpenStack manages on
the specific implementation.
You can find the measurements available per hypervisor and OpenStack release on
the OpenStack site.
You can use 'ceilometer meter-list' to list the available meters.
.. code-block:: bash
For more information:
http://docs.openstack.org/developer/ceilometer/measurements.html
$ compute_available_monitors=nova.compute.monitors.all_monitors
$ compute_monitors=ComputeDriverCPUMonitor
Ceilometer is designed to collect measurements from OpenStack services and from
other external components. If you would like to add new meters to the currently
existing ones, you need to follow the documentation below:
#. Restart the Nova compute service and the Nova scheduler after completing the above configuration.
#. http://docs.openstack.org/developer/ceilometer/new_meters.html
#. For more information: `Integrating your metrics plug-in with Nova <http://www-01.ibm.com/support/knowledgecenter/SS8MU9_2.2.0/Admin/tasks/integratingplugin.dita>`_
The Ceilometer collector uses a pluggable storage system, meaning that you can
pick any database system you prefer.
The original implementation has been based on MongoDB but you can create your
own storage driver using whatever technology you want.
