[1] | Change settings for Cinder service to enable Telemetry data collention like follows. Change on all Nodes Cinder services are running. |
[root@dlp ~(keystone)]#
vi /etc/cinder/cinder.conf # add to the end [oslo_messaging_notifications] driver = messagingv2 transport_url = rabbit://openstack:password@10.0.0.30 systemctl restart openstack-cinder-api openstack-cinder-scheduler |
[2] | It's some example to display metrics and meters. |
