AWS – CloudWatchアラーム
概要
CloudWatchアラームの情報を取得する方法について記載しています。
CloudWatchアラーム
1 つのメトリクスを監視する CloudWatch アラームを作成できます。このアラームは、複数の期間にわたるしきい値とメトリクスの値の関係性に基づき、1 つ以上のアクションを実行します。アクションには、Amazon EC2 アクション、Amazon EC2 Auto Scaling アクション、または Amazon SNS トピックに送信される通知があります。CloudWatch ダッシュボードにアラームを追加して視覚的に監視することもできます。ダッシュボードにある場合、ALARM状態になると、アラームは赤に変わるため、状態を事前にモニタリングしやすくなります。
