Enable Block Storage meters¶

Telemetry uses notifications to collect Block Storage service meters. Perform these steps on the controller and Block Storage nodes.

Note

Your environment must include the Block Storage service.

Configure Cinder to use Telemetry¶

Edit the /etc/cinder/cinder.conf file and complete the following actions:

In the [DEFAULT] section, configure notifications:

[DEFAULT]
...
notification_driver = messagingv2

Restart the Block Storage services on the controller node:

# systemctl restart openstack-cinder-api.service openstack-cinder-scheduler.service

Restart the Block Storage services on the storage nodes:
```
# systemctl restart openstack-cinder-volume.service
```

Use the cinder-volume-usage-audit command on Block Storage nodes to retrieve meters on demand. For more information, see the Cloud Administrator Guide.
