7.11. マスターおよびノードログの表示
OpenShift Container Platform は、ノードの systemd-journald.service
およびスクリプトを使用して、デバッグ用にログメッセージを収集します (マスターの場合は master-logs
を使用)。
Web コンソールに表示される行数は 5000 にハードコーディングされ、これを変更することはできません。ログ全体を表示するには、CLI を使用します。
ロギングでは、以下のような Kubernetes のロギング規則に基づいて 5 段階のログメッセージの重要度を使用します。
オプション | 説明 |
---|---|
0 | エラーと警告のみ |
2 | 通常の情報 |
4 | デバッグレベルの情報 |
6 | API レベルのデバッグ情報 (要求 / 応答) |
8 | 本体レベルの API のデバッグ情報 |
ユーザーは、必要に応じて マスターまたはノードのログレベルをそれぞれ別個に変更できます。
ノードログの表示
ノードシステムのログを表示するには、以下のコマンドを実行します。
# journalctl -r -u <journal_name>
最新のエントリーから表示するには、-r
オプションを使用します。
マスターログの表示
マスターコンポーネントのログを表示するには、以下のコマンドを実行します。
# /usr/local/bin/master-logs <component> <container>
以下に例を示します。
# /usr/local/bin/master-logs controllers controllers # /usr/local/bin/master-logs api api # /usr/local/bin/master-logs etcd etcd
マスターログのファイルへのリダイレクト
マスターログの出力をファイルにリダイレクトするには、以下のコマンドを実行します。
master-logs api api 2> file
7.11.1. ロギングレベルの設定
DEBUG_LOGLEVEL
オプションをマスターの/etc/origin/master/master.env ファイルに設定するか、ノードの /etc/sysconfig/atomic-openshift-node ファイルに設定して、ログに記録する INFO メッセージを制御できます。すべてのメッセージを収集するようにログを設定すると、解釈が困難な膨大なログが生成され、多くの領域が占領されます。すべてのメッセージの収集は、デバッグで使用する場合にとどめる必要があります。
FATAL、ERROR、WARNING、および一部の INFO の重要度を伴うメッセージは、ログの設定に関係なくログに表示されます。
ロギングレベルを変更するには、以下を実行します。
- マスターの /etc/origin/master/master.env ファイル、またはノードの /etc/sysconfig/atomic-openshift-node ファイルを編集します。
Log Level Options 表の値を
DEBUG_LOGLEVEL
フィールドに入力します。以下に例を示します。
DEBUG_LOGLEVEL=4
- マスターまたはノードを再起動します。OpenShift Container Platform サービスの再起動 を参照してください。
再起動後は、すべての新しいログメッセージは新しい設定に従ったメッセージに従います。古いメッセージは変更されません。
デフォルトのログレベルは標準のクラスターインストールプロセスを使用して設定できます。詳細は、クラスター変数 を参照してください。
以下の例は、各種のログレベルのリダイレクトされたマスターログファイルの抜粋です。システム情報はこれらの例から削除されています。
