HAProxy

Supported OS Linux Windows

Integrationv4.4.0

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。

コンフィギュレーション

Prometheus の使用

このインテグレーションを設定するための推奨される方法は、HAProxy で Prometheus エンドポイントを有効にすることです。このエンドポイントは、バージョン 2 (エンタープライズバージョン 1.9rc1) 以降の HAProxy に組み込まれています。古いバージョンを使用している場合は、HAProxy Prometheus エクスポーターを設定するか、次のセクションで説明するレガシーソケットベースのインテグレーションを設定することを検討してください。

HAProxy の準備

  1. 公式ガイドを使用して haproxy.conf を構成します。
  2. HAProxy を再起動して、Prometheus エンドポイントを有効にします

Agent の構成

ホスト

メトリクスの収集

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. HAProxy メトリクス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 haproxy.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。

    instances:
    
      ## @param use_openmetrics - boolean - optional - default: false
      ## Enable to preview the new version of the check which supports HAProxy version 2+
      ## or environments using the HAProxy exporter.
      ##
      ## OpenMetrics-related options take effect only when this is set to `true`. 
      ##
      ## Uses the latest OpenMetrics V2 implementation for more features and better performance.
      ## Note: To see the configuration options for the OpenMetrics V1 implementation (Agent 7.33 or older),
      ## https://github.com/DataDog/integrations-core/blob/7.33.x/haproxy/datadog_checks/haproxy/data/conf.yaml.example
      #
    - use_openmetrics: true  # Enables OpenMetrics V2
    
      ## @param openmetrics_endpoint - string - optional
      ## The URL exposing metrics in the OpenMetrics format.
      #
      openmetrics_endpoint: http://localhost:<PORT>/metrics
    

    : use_openmetrics オプションはメトリクスの収集に OpenMetrics v2 を使用します。これは Agent v7.35+ または Agent v6.35+ で Python 3 を有効にする必要があります。Python 3 を使用できないホスト、または Agent v7.34 以下のホストでは、OpenMetrics v1 の実装またはソケットベースのレガシーインテグレーションを使用します。

    レガシー実装の構成オプションを表示するには、Agent v7.34 の サンプル haproxy.d/conf.yaml ファイルをご覧ください。

  2. 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>{"openmetrics_endpoint": "http://%%host%%:<PORT>/metrics", "use_openmetrics": "true"}
Kubernetes のデプロイメント例

デプロイメントの .spec.template.metadata の下にポッドアノテーションを追加します。

        ad.datadoghq.com/haproxy.instances: |
          [
            {
              "openmetrics_endpoint": "http://%%host%%:<PORT>/metrics", "use_openmetrics": "true"
            }
          ]          
    spec:
      containers:
        - name: haproxy

統計エンドポイントの使用

: このコンフィギュレーション戦略は、レガシーユーザー向けのリファレンスとして提供されています。初めてインテグレーションを設定する場合は、前のセクションで説明した Prometheus ベースの戦略の使用を検討してください。

Agent は、メトリクスを統計エンドポイントを使って収集します。

  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

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

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

Docker

コンテナで実行中の Agent に対してこのチェックを構成するには:
