Installing and Running the Development Version
|
|
================================================
|
|
|
|
Ceilometer has four daemons. The :term:`compute agent` runs on the
|
|
Nova compute node(s) while the :term:`central agent` and
|
|
:term:`collector` run on the cloud's management node(s). In a
|
|
development environment created by devstack_, these two are typically
|
|
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.

Configuring Devstack
|
|
====================
|
|
|
|
.. index::
|
|
double: installing; devstack
|
|
|
|
1. Create a ``localrc`` file as input to devstack.
|
|
|
|
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 ``localrc`` before running ``stack.sh``.
|
|
|
|
This example ``localrc`` file shows all of the settings required for
|
|
ceilometer::
|
|
|
|
# Enable the ceilometer services
|
|
enable_service ceilometer-acompute,ceilometer-acentral,ceilometer-collector,ceilometer-api
