How to configure EventBridge to run a powershell document on target machines when ever a CloudWatch alarm is triggered.

Question

When I receive an Amazon CloudWatch alarm notification for memory high, high cpu and high disk utilization, I want to run a powershell document that will capture the processes or files using the most resources and email that information or dump in an s3 bucket for review. I will like to leverage EventBridge for this solution.

Hello ,

You need to use SSM Automation document as target of your EventBridge event.

Thanks Nabil. Additionally, worth mentioning that all CloudWatch alarms are set in one account and the machines are in a different AWS account. I am certain that I can configure a cross region/account event bridge, but not so sure how I can feed the alarm status into event bus in account A, then pass that on to event bus in account B to then execute the Powershell document. So what would be your opinion of a high level design in this case?
