OpenStack Telemetry is an API service that provides a collector and a range of disparate agents. This procedure details how to install the agent that runs on the compute node. Install the Telemetry service on the Compute node: # apt-get install ceilometer-agent-compute # yum install openstack-ceilometer-compute # zypper install openstack-ceilometer-agent-compute Set the following options in the /etc/nova/nova.conf file: # openstack-config --set /etc/nova/nova.conf DEFAULT instance_usage_audit True # openstack-config --set /etc/nova/nova.conf DEFAULT instance_usage_audit_period hour # openstack-config --set /etc/nova/nova.conf DEFAULT notify_on_state_change vm_and_task_state # openstack-config --set /etc/nova/nova.conf DEFAULT notification_driver nova.openstack.common.notifier.rpc_notifier # openstack-config --set /etc/nova/nova.conf DEFAULT notification_driver ceilometer.compute.nova_driver Edit the /etc/nova/nova.conf file and add the following lines to the [DEFAULT] section: ... [DEFAULT] ... instance_usage_audit=True instance_usage_audit_period=hour notify_on_state_change=vm_and_task_state notification_driver=nova.openstack.common.notifier.rpc_notifier notification_driver=ceilometer.compute.nova_notifier You must set the secret key that you defined previously. The Telemetry service nodes share this key as a shared secret: # openstack-config --set /etc/ceilometer/ceilometer.conf publisher_rpc metering_secret $ADMIN_TOKEN Edit the /etc/ceilometer/ceilometer.conf file and change these lines in the [DEFAULT] section. Replace ADMIN_TOKEN with the admin token that you created previously: ... [publisher_rpc] # Secret value for signing metering messages (string value) metering_secret = ADMIN_TOKEN ... Restart the service with its new settings: # service ceilometer-agent-compute restart Start the service and configure it to start when the system boots: # service openstack-ceilometer-agent-compute start # chkconfig openstack-ceilometer-agent-compute on # service openstack-ceilometer-compute start # chkconfig openstack-ceilometer-compute on
