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 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。
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.conf
を構成します。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:
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
注: 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。
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。
パラメーター | 値 |
---|---|
<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"} |
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。

注: 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。
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
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 のメトリクスと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。
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
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。
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
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。
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。
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:
アプリケーションのコンテナで、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を Docker ラベルとして設定します。
LABEL "com.datadoghq.ad.check_names"='["haproxy"]'
LABEL "com.datadoghq.ad.init_configs"='[{}]'
LABEL "com.datadoghq.ad.instances"='[{"url": "https://%%host%%/admin?stats"}]'
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、Docker ログ収集を参照してください。
次に、ログインテグレーションを Docker ラベルとして設定します。
LABEL "com.datadoghq.ad.logs"='[{"source":"haproxy","service":"<SERVICE_NAME>"}]'
このチェックを、Kubernetes で実行している Agent に構成します。
アプリケーションのコンテナで、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をポッドアノテーションとして設定します。他にも、ファイル、ConfigMap、または key-value ストアを使用してテンプレートを構成できます。

syslog があるシステムで、Agent がポート 514 で HAProxy ログをリッスンしている場合、Agent ログに以下のエラーが表示されることがあります:
Can't start UDP forwarder on port 514: listen udp :514: bind: address already in use
これは、デフォルトで syslog がポート 514 でリッスンしているために起こっています。このエラーを解決するには、syslog を無効にするか、ポート 514 と Agent がログをリッスンしている別のポートにログを転送するように HAProxy を構成することができます。Agent がリッスンするポートは、こちらで haproxy.d/conf.yaml ファイル定義することができます。
