概要

このチェックは、Datadog Agent を通じて IBM Db2 を監視します。

セットアップ

インストール

IBM Db2 チェックは Datadog Agent パッケージに含まれています。

依存関係

ibm_db クライアントライブラリが必要です。これをインストールするには、コンパイラーが用意されていることを確認し、次を実行します。

Unix
/opt/datadog-agent/embedded/bin/pip install ibm_db==3.0.1
Windows

Agent バージョン < 6.11 の場合

"C:\Program Files\Datadog\Datadog Agent\embedded\python.exe" -m pip install ibm_db==3.0.1

Agent バージョン >= 6.12 の場合

"C:\Program Files\Datadog\Datadog Agent\embedded<PYTHON_MAJOR_VERSION>\python.exe" -m pip install ibm_db==3.0.1

Linux では、XML 機能が必要になる場合があります。ビルドプロセス中にエラーが発生した場合は、 libxslt-dev (RPM では libxslt-devel) をインストールしてください。

権限

一部のテーブルからのメトリクスを問い合わせるには、選択した Db2 ユーザーに特別な権限を付与する必要があります。 インスタンスマスターユーザーに切り替えて、db2 プロンプトで次のコマンドを実行します。

update dbm cfg using HEALTH_MON on
update dbm cfg using DFT_MON_STMT on
update dbm cfg using DFT_MON_LOCK on
update dbm cfg using DFT_MON_TABLE on
update dbm cfg using DFT_MON_BUFPOOL on

これで、get dbm cfg を実行すると、次のように表示されます。

 Default database monitor switches
   Buffer pool                         (DFT_MON_BUFPOOL) = ON
   Lock                                   (DFT_MON_LOCK) = ON
   Sort                                   (DFT_MON_SORT) = OFF
   Statement                              (DFT_MON_STMT) = ON
   Table                                 (DFT_MON_TABLE) = ON
   Timestamp                         (DFT_MON_TIMESTAMP) = ON
   Unit of work                            (DFT_MON_UOW) = OFF
 Monitor health of instance and databases   (HEALTH_MON) = ON

コンフィギュレーション

ホスト

ホストで実行中の Agent に対してこのチェックを構成するには:

メトリクスの収集
  1. ibm_db2 のパフォーマンスデータの収集を開始するには、Agent のコンフィギュレーションディレクトリのルートにある conf.d/ フォルダーの ibm_db2.d/conf.yaml ファイルを編集します。使用可能なすべてのコンフィギュレーションオプションについては、サンプル ibm_db2.d/conf.yaml を参照してください。

  2. Agent を再起動します

ログの収集

Agent バージョン 6.0 以降で利用可能

  1. Datadog Agent で、ログの収集はデフォルトで無効になっています。以下のように、datadog.yaml ファイルでこれを有効にします。

    logs_enabled: true
    
  2. IBM Db2 のログの収集を開始するには、次の構成ブロックを ibm_db2.d/conf.yaml ファイルに追加します。

    logs:
      - type: file
        path: /home/db2inst1/sqllib/db2dump/db2diag.log
        source: ibm_db2
        service: db2sysc
        log_processing_rules:
          - type: multi_line
            name: new_log_start_with_date
            pattern: \d{4}\-(0?[1-9]|[12][0-9]|3[01])\-(0?[1-9]|1[012])
    
  3. Agent を再起動します

コンテナ化

コンテナ環境の場合は、オートディスカバリーのインテグレーションテンプレートのガイドを参照して、次のパラメーターを適用してください。

メトリクスの収集
パラメーター
<インテグレーション名>ibm_db2
<初期コンフィギュレーション>空白または {}
<インスタンスコンフィギュレーション>{"db": "<DB_NAME>", "username":"<USERNAME>", "password":"<PASSWORD>", "host":"%%host%%", "port":"%%port%%"}
ログの収集

Agent バージョン 6.0 以降で利用可能

Datadog Agent で、ログの収集はデフォルトで無効になっています。有効にする方法については、Kubernetes ログ収集のドキュメントを参照してください。

パラメーター
<LOG_CONFIG>{"source": "ibm_db2", "service": "<SERVICE_NAME>", "log_processing_rules": {"type":"multi_line","name":"new_log_start_with_date", "pattern":"\d{4}\-(0?[1-9]|[12][0-9]|3[01])\-(0?[1-9]|1[012])"}}

検証

Agent の status サブコマンドを実行し、Checks セクションで ibm_db2 を探します。
