|
This is how to use OpenStack Telemetry Service (Ceilometer) for Nova Compute service.
This example is based on the environment like follows.

| [1] | Change settings for Nova Compute service to enable Telemetry data collention like follows. |
|
[root@node01 ~]#
vi /etc/nova/nova.conf # add follows into [DEFAULT] section
instance_usage_audit = True
instance_usage_audit_period = hour notify_on_state_change = vm_and_task_state # add to the end [oslo_messaging_notifications] driver = messagingv2 systemctl restart openstack-nova-compute |
| [2] | It's some example to display metrics and meters. |
