Amazon Elastic Load Balancing

概要

Amazon Elastic Load Balancing は、クラウド上の複数の Amazon EC2 インスタンスに受信アプリケーションのトラフィックを自動的に分散します。

Datadog は、AWS が提供する 3 種類の Elastic Load Balancer (Application (ALB)、Classic (ELB)、Network Load Balancers (NLB)) からメトリクスとメタデータを収集します。

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

注: このインテグレーションでは、’ec2:describe**’ と ’elasticloadbalancing:describe*’ の権限が完全に有効になっている必要があります。

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、ApplicationELBELBNetworkELBMetric Collection タブで有効になっていることを確認します。
  2. Datadog - Amazon ELB インテグレーションをインストールします。
