OpenStack Caracal : Ceilometer 設定 (Network ノード)2024/04/11

OpenStack Telemetry Service (Ceilometer) をインストールします。

当例では以下のような環境を例に Ceilometer サービスをインストールします。

[1]	こちらを参考に事前に Gnocchi をインストールしておきます。当例では Ceilometer で収集したデータを Gnocchi へ保管するよう設定します。
[2]	Control ノードの Keystone に Ceilometer 用のユーザー等々を登録しておきます。
