[root@node01 ~]#
vi /etc/nova/nova.conf # [DEFAULT] セクション内の任意の場所へ追記
instance_usage_audit = True
instance_usage_audit_period = hour notify_on_state_change = vm_and_task_state # 最終行へ追記 [oslo_messaging_notifications] driver = messagingv2 systemctl restart openstack-nova-compute |
| [2] | 任意のユーザーでインスタンスを作成/起動した場合に収集されるデータの表示例です。 |
