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
localrc
file 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_audit
to true in the nova configuration file.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
The ceilometer services are not enabled by default, so they must be enabled in
localrc
before runningstack.sh
.
This example localrc
file shows all of the settings
required for ceilometer:
# Enable the ceilometer metering services
enable_service ceilometer-acompute,ceilometer-acentral,ceilometer-collector
# Enable the ceilometer alarming services
enable_service ceilometer-alarm-singleton,ceilometer-alarm-notifier
# Enable the ceilometer api services
enable_service ceilometer-api
