[1] Image サービスの各種データ収集を有効にするには、Glance を以下のように設定します。
[root@dlp ~(keystone)]#
vi /etc/glance/glance-api.conf
# 最終行へ追記

[oslo_messaging_notifications]
driver = messagingv2
# RabbitMQ 接続情報
transport_url = rabbit://openstack:password@10.0.0.30
[root@dlp ~(keystone)]#
vi /etc/glance/glance-registry.conf
# 最終行へ追記

[oslo_messaging_notifications]
driver = messagingv2
# RabbitMQ 接続情報
transport_url = rabbit://openstack:password@10.0.0.30
[root@dlp ~(keystone)]#
systemctl restart openstack-glance-api openstack-glance-registry

[2] Control ノードでの収集データの表示例です。
