Enable Block Storage meters for Red Hat Enterprise Linux and CentOS¶

Configure Cinder to use Telemetry¶

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

• In the [oslo_messaging_notifications] section, configure notifications:

  [oslo_messaging_notifications]
  ...
  driver = messagingv2
  

• Enable periodic usage statistics relating to block storage. To use it, you must run this command in the following format:

  $ cinder-volume-usage-audit  --start_time='YYYY-MM-DD HH:MM:SS' \
    --end_time='YYYY-MM-DD HH:MM:SS' --send_actions
  

  This script outputs what volumes or snapshots were created, deleted, or exists in a given period of time and some information about these volumes or snapshots.

  Using this script via cron you can get notifications periodically, for example, every 5 minutes:

  */5 * * * * /path/to/cinder-volume-usage-audit --send_actions
  

Finalize installation¶

1. Restart the Block Storage services on the controller node:

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

2. Restart the Block Storage services on the storage nodes:

   # systemctl restart openstack-cinder-volume.service
