HAProxy

Agent Check Agentチェック

Supported OS: Linux Mac OS Windows

HAProxy 付属のダッシュボード

概要

Datadog で HAProxy のアクティビティをキャプチャして、以下のことができます。

  • HAProxy の負荷分散パフォーマンスを視覚化できます。
  • サーバーがダウンしたときに気付くことができます。
  • HAProxy のパフォーマンスを他のアプリケーションと関連付けることができます。

セットアップ

インストール

Haproxy チェックは Datadog Agent パッケージに含まれています。Haproxy サーバーには何もインストールする必要がありません。

HAProxy の準備

バージョン < 2

Agent は、メトリクスを統計エンドポイント経由で収集します。

  1. haproxy.conf で統計エンドポイントを構成します。

      listen stats # Define a listen section called "stats"
      bind :9000 # Listen on localhost:9000
      mode http
      stats enable  # Enable stats page
      stats hide-version  # Hide HAProxy version
      stats realm Haproxy\ Statistics  # Title text for popup window
      stats uri /haproxy_stats  # Stats URI
      stats auth Username:Password  # Authentication credentials
    
  2. HAProxy を再起動して、統計エンドポイントを有効にします

バージョン >= 2

このチェックは、Prometheus エンドポイントに基づく HAProxy バージョン 2 以降の新しい実装をサポートします。

  1. 公式ガイドを使用して haproxy.conf を構成します。

  2. haproxy.d/conf.yaml で設定 use_prometheus有効にします。

  3. HAProxy を再起動して、統計エンドポイントを有効にします

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:

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 haproxy.d/conf.yaml ファイルを編集し、HAProxy のメトリクスログの収集を開始します。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、haproxy.d/conf.yaml のサンプルを参照してください。

メトリクスの収集
  1. Haproxy のメトリクスの収集を開始するには、haproxy.d/conf.yaml ファイルに次の構成ブロックを追加します。

    init_config:
    
    instances:
      ## @param url - string - required
      ## Haproxy URL to connect to gather metrics.
      ## Set the according <USERNAME> and <PASSWORD> or use directly a unix stats
      ## or admin socket: unix:///var/run/haproxy.sock
      #
      - url: http://localhost/admin?stats
    
  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

デフォルトで、Haproxy はログを UDP 経由で 514 ポートに送信します。Agent はこのポートでログをリッスンできますが、1024 よりも下のポート番号にバインディングするため、管理者特権が必要になります。以下ではこの設定方法について説明します。別のポートを使用することも可能で、その場合は手順 3 をスキップしてください。

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

    logs:
      - type: udp
        port: 514
        service: <SERVICE_NAME>
        source: haproxy
    

    環境に合わせて、service パラメーターの値を変更し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の詳細については、サンプル haproxy.d/conf.yaml を参照してください。

  3. setcap コマンドを使用して、514 ポートへのアクセスを許可します。

    sudo setcap CAP_NET_BIND_SERVICE=+ep /opt/datadog-agent/bin/agent/agent
    

    セットアップが正しいか確認するために、getcap コマンドを実行します。

    sudo getcap /opt/datadog-agent/bin/agent/agent
    

    正しければ、次のように出力されます。

    /opt/datadog-agent/bin/agent/agent = cap_net_bind_service+ep
    

    注: この setcap コマンドを、Agent をアップグレードするたびに実行してください。

  4. 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>haproxy
<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>{"url": "https://%%host%%/admin?stats"}
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": "haproxy", "service": "<SERVICE_NAME>"}

検証

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