Cloudwatch警报可同时监视所有EC2实例的状态检查

Question

How can we monitor the system status check of all EC2 instances simultaneously rather than setting up cloudwatch alarm at each EC2 level individually?

If it's not possible via cloudwatch service, can it be done using boto3?

Answer 1

如果您不想单独设置警报，则可以将其自动化，每当启动新实例时，您都可以设置cloudwatch规则（当实例状态从挂起变为联机时）以触发lambda函数，在lambda函数中，您可以设置cloudwatch该实例的警报，对于已经存在的实例，您也可以在不对该脚本进行少许修改的情况下设置警报。
