These files really only work for a devstack setup, but the demonstrate what one would need to do in a real deployment behind mod_wsgi. Change-Id: If60ce2aa0b89c055ccc0411aece28042b14ab633 Signed-off-by: Doug Hellmann <doug.hellmann@dreamhost.com>

Installing and Running the Development Version
Ceilometer has four daemons. The compute agent runs on the Nova compute node(s) while
the central agent and
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
double: installing; devstack
- Create a
localrcfile as input to devstack. - Ceilometer makes extensive use of the messaging bus, but has not yet been tested with ZeroMQ. We recommend using Rabbit or qpid for now.
- Nova does not generate the periodic notifications for all known
instances by default. To enable these auditing events, set
instance_usage_auditto true in the nova configuration file. - The ceilometer services are not enabled by default, so they must be
enabled in
localrcbefore runningstack.sh.
This example localrc file shows all of the settings
required for ceilometer:
# Enable the ceilometer services
