Telemetry uses notifications to collect Image service meters. Perform these steps on the controller node.
Edit the /etc/glance/glance-api.conf and /etc/glance/glance-registry.conf files and complete the following actions:
In the [DEFAULT] and [oslo_messaging_rabbit] sections, configure notifications and RabbitMQ message broker access:
[DEFAULT]
...
notification_driver = messagingv2
rpc_backend = rabbit
[oslo_messaging_rabbit]
...
rabbit_host = controller
rabbit_userid = openstack
rabbit_password = RABBIT_PASS
Replace RABBIT_PASS with the password you chose for the openstack account in RabbitMQ.
Restart the Image service:
# systemctl restart openstack-glance-api.service openstack-glance-registry.service
