インテグレーションバージョン5.1.0

概要

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

計画と使用

ホストで実行されている Agent 用にこのチェックをインストールおよび構成する場合は、以下の手順に従ってください。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この手順を行ってください。

インフラストラクチャーリスト

ProxySQL インテグレーションは Datadog Agent パッケージに含まれています。サーバーに追加でインストールする必要はありません。

ブラウザトラブルシューティング

SSL の有効化

フル SSL/TLS 検証を使用して ProxySQL に接続するには、conf.yaml ファイルで tls_verify オプションを有効にします。SSL/TLS による接続に必要な証明書とパスワードを含めます。

    tls_verify: true
    tls_ca_cert: ca_cert.pem

メトリクスベース SLO

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

  1. ProxySQL 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 proxysql.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 proxysql.d/conf.yaml を参照してください。

  2. Agent を再起動します

収集データ
  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. ProxySQL のログの収集を開始するには、該当のログファイルを proxysql.d/conf.yaml ファイルに追加します。

      logs:
          # Default logging file
        - type: file
          path: /var/log/proxysql.log
          source: proxysql
          service: "<SERVICE_NAME>"
          # Logged queries, file needs to be in JSON
          # https://github.com/sysown/proxysql/wiki/Query-Logging
        - type: file
          path: "<QUERY_LOGGING_FILE_PATH>"
          source: proxysql
          service: "<SERVICE_NAME>"
          # Audit log
          # https://github.com/sysown/proxysql/wiki/Audit-log
        - type: file
          path: "<AUDIT_LOG_FILE_PATH>"
          source: proxysql
          service: "<SERVICE_NAME>"
    

    path パラメーターと service パラメーターの値を変更し、環境に合わせて構成してください。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 proxysql.d/conf.yaml を参照してください。

  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
<INTEGRATION_NAME>proxysql
<INIT_CONFIG>空白または {}
<INSTANCE_CONFIG>{"host": "%%host%%", "port": "%%port%%", "username": "<ユーザー>", "password": "<パスワード>"}
収集データ

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 ログ収集を参照してください。

パラメーター
<LOG_CONFIG>{"source": "proxysql", "service": "<サービス名>"}

検証

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