================================================
Installing and Running the Development Version
================================================
Ceilometer has several daemons. The basic are: :term:`compute agent` runs on
the Nova compute node(s) while the :term:`central agent`, :term:`collector`
and :term:`notification agent` run on the cloud's management node(s).
In a development environment created by devstack_, these services are
typically running on the same server. They do not have to be, though, so some
of the instructions below are duplicated. Skip the steps you have already done.
.. _devstack: http://www.devstack.org/
Configuring Devstack
====================
.. index::
double: installing; devstack
1. Create a ``local.conf`` file as input to devstack.
.. note::
``local.conf`` replaces the former configuration file called ``localrc``.
If you used localrc before, remove it to switch to using the new file.
For further information see the `localrc description page
<http://devstack.org/localrc.html>`_ or `devstack configuration
<http://devstack.org/configuration.html>`_.
2. Ceilometer makes extensive use of the messaging bus, but has not
yet been tested with ZeroMQ. We recommend using Rabbit or qpid for
now.
3. Nova does not generate the periodic notifications for all known
instances by default. To enable these auditing events, set
``instance_usage_audit`` to true in the nova configuration file.
4. Cinder does not generate notifications by default. To enable
these auditing events, set the following in the cinder configuration file::
notification_driver=cinder.openstack.common.notifier.rpc_notifier
5. The ceilometer services are not enabled by default, so they must be
enabled in ``local.conf`` before running ``stack.sh``.
This example ``local.conf`` file shows all of the settings required for
ceilometer::
[[local|localrc]]
# Enable the ceilometer metering services
enable_service ceilometer-acompute ceilometer-acentral ceilometer-anotification ceilometer-collector
# Enable the ceilometer alarming services
enable_service ceilometer-alarm-evaluator,ceilometer-alarm-notifier
# Enable the ceilometer api services
enable_service ceilometer-api
The first group of daemons are necessary for core ceilometer functionality:
polling, event listening, and data collection.
6. If you use Data Processing (Sahara) service at your DevStack, it will
generate notifications by default.
