| [1] | Change settings for Cinder service to enable Telemetry data collection like follows. Change on all Nodes Cinder services are running. |
|
root@dlp ~(keystone)#
vi /etc/cinder/cinder.conf # add to last line [oslo_messaging_notifications] driver = messagingv2 transport_url = rabbit://openstack:password@dlp.srv.world:5672 systemctl restart apache2 cinder-scheduler |
| [2] | It's some examples to display metrics and meters. |
