概要

ネットワークチェックは、ホストオペレーティングシステムから TCP/IP 統計を収集します。

セットアップ

以下の手順に従って、このチェックをインストールし、ホストで実行中の Agent に対して構成します。

インストール

ネットワークチェックは 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。

このインテグレーションを使用してメトリクスを収集するには、ホストで conntrack モジュールがアクティブにされていることを確認します。アクティブにされていない場合は、次のコマンドを実行します。

sudo modprobe nf_conntrack
sudo modprobe nf_conntrack_ipv4
sudo modprobe nf_conntrack_ipv6

: Agent イメージに conntrack バイナリをインストールする必要がある場合があります。

コンフィギュレーション

  1. Agent はデフォルトでネットワークチェックを有効にしますが、チェックを自分で構成する場合は、Agent の構成ディレクトリのルートにある conf.d/ フォルダーの network.d/conf.yaml ファイルを編集します。使用可能なすべての構成オプションの詳細については、サンプル network.d/conf.yaml を参照してください。

  2. Agent を再起動すると、構成の変更が有効になります。

:

一部の conntrack メトリクスを取得するには、特権的なアクセスで conntrack を実行する必要があります。

Linux: それには、次の sudoers ルールを構成します。

dd-agent ALL=NOPASSWD: /usr/sbin/conntrack -S

Kubernetes: Conntrack メトリクスは、Kubernetes v1.11 未満の場合はデフォルトで、Kubernetes v1.11 以上の場合は host ネットワークモードを使用している場合に使用できます。

検証

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