[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 openstack-glance-api |
| [2] | It's some example to display metrics and meters. |
