[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
notify_on_state_change = vm_and_task_state
# 最終行へ追記

[oslo_messaging_notifications]
driver = messagingv2
root@node01:~#
systemctl restart nova-compute
