| [1] | Change settings for Glance service to enable Telemetry data collection like follows. |
|
root@dlp ~(keystone)#
vi /etc/glance/glance-api.conf # add to the end [oslo_messaging_notifications] driver = messagingv2 # RabbitMQ connection info transport_url = rabbit://openstack:password@dlp.srv.world systemctl restart glance-api |
| [2] | It's some example to display metrics and meters. |
