Cloudwatch「StatusCheckFailed」系の監視メトリクスで障害発生テスト

Last updated at Posted at 2019-09-07

StatusCheckFailed_Instance

インスタンス毎のソフトウェアとネットワーク監視
サーバ停止してもデータなし扱いとなるので、障害テストできない

疑似障害発生方法

systemctl stop network

15:20前に、ネットワーク停止させた

コンソール上から直接再起動してあげると復活

StatusCheckFailed_System

インスタンスを使用するためのAWSインフラ全体の監視
疑似的な障害テストはできない

StatusCheckFailed

StatusCheckFailed_InstanceとStatusCheckFailed_Systemのどちらかが異常な場合、異常と判定する。
最低これだけチェックしておけばいい感じ？
