MackerelはAWSインテグレーションにてAmazon ElastiCacheのメトリック取得や監視に対応しています。 AWSインテグレーションで連携をおこなった場合、課金対象として 1ノード = 1マイクロホスト と換算します。またそれに加えて、取得されるメトリックの数に応じて、1マイクロホストあたりのメトリック数上限の超過による請求が行われる場合があります。
AWSインテグレーションの設定方法や対応AWSサービス一覧についてはこちらのページをご確認ください。
AWSインテグレーション
取得メトリック
AWSインテグレーションのElastiCache対応で取得できるメトリックは以下の通りです。 メトリック の説明に関してはAWSのヘルプ(ホストレベル、Memcached、Redis)をご確認ください。
Memcachedの場合は最大で48個、Redisの場合は最大で70個のメトリックが取得されます。
