[1]	Compute サービスの各種データ収集を有効にするには、Compute ノードの Nova Compute を以下のように設定します。

[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

# 最終行へ追記
[notifications]
notify_on_state_change = vm_and_task_state

[oslo_messaging_notifications]
driver = messagingv2

[root@node01 ~]#

systemctl restart openstack-nova-compute

[2]	任意のユーザーでインスタンスを起動した場合に収集されるデータの表示例です。
