|
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 collection like follows. |
|
root@node01:~#
vi /etc/nova/nova.conf # add follows into [DEFAULT] section instance_usage_audit = True instance_usage_audit_period = hour # add to the end [notifications] notify_on_state_change = vm_and_task_state [oslo_messaging_notifications] driver = messagingv2 systemctl restart nova-compute |
| [2] | It's some example to display metrics and meters. |
