Amazon Elastic Block Store

概要

Amazon EBS は、AWS Cloud 内の Amazon EC2 インスタンスと共に使用される永続的ブロックストレージボリュームです。

このインテグレーションを有効にすると、Datadog にすべての EBS 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 EBS が有効になっていることを確認します。
  2. Datadog - AWS EBS インテグレーションをインストールします。

注: このインテグレーションは、監視対象の EC2 に接続された EBS ボリュームのメトリクスを収集します。すべての EBS メトリクスを収集するには、AWS インテグレーションページで EC2 にチェックを入れ、リソース収集を制限する設定で EC2 を監視対象から除外していないことを確認します。

ログの収集

ログの有効化

Amazon EBS 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。

注: S3 バケットにログを送る場合は、Target prefix が amazon_ebs 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、Amazon EBS ログを含む S3 バケットまたは CloudWatch のロググループに手動でトリガーを追加します。
