[1] Block Storage サービスの各種データ収集を有効にするには、Cinder を以下のように設定します。
Cinder 関連サービスが稼働する全ノードで設定変更します。
[root@dlp ~(keystone)]#
vi /etc/cinder/cinder.conf
# 最終行へ追記

[oslo_messaging_notifications]
driver = messagingv2
transport_url = rabbit://openstack:password@10.0.0.30
[root@dlp ~(keystone)]#
systemctl restart openstack-cinder-api openstack-cinder-scheduler

[2] 任意のユーザーでボリュームを作成した場合に収集されるデータの表示例です。
