概要

AWS NAT Gateway を使用すると、プライベートサブネットのインスタンスからインターネットに接続できても、インターネットからはこれらのインスタンスとの接続を開始できないようにすることができます。

このインテグレーションを有効にすると、Datadog にすべての NAT Gateway メトリクスを表示できます。

セットアップ

インストール

Amazon Web Services インテグレーションをまだセットアップしていない場合は、最初にセットアップします。

メトリクスの収集

  1. AWS インテグレーションページで、Metric Collection タブの下にある NATGateway が有効になっていることを確認します。
  2. Datadog - AWS NAT Gateway インテグレーションをインストールします。

収集データ

ログの有効化

AWS NAT Gateway から S3 バケットまたは CloudWatch のいずれかにログを送信するよう構成します。

: S3 バケットにログを送る場合は、Target prefixamazon_nat_gateway に設定されているかを確認してください。

ログを Datadog に送信する方法

  1. Datadog Forwarder Lambda 関数をまだセットアップしていない場合は、セットアップします。

  2. Lambda 関数がインストールされたら、AWS コンソールから手動で、AWS NAT Gateway ログを含む CloudWatch ロググループにトリガーを追加します。
