Question

is it possible to pass EC2 instance-id stored as a parameter in SSM to Cloud-Watch event rule.

EC2 will created by AutoScaling and its Instance-Id will be stored in SSM. Now I wanted to pass my SSM parameter to CloudWatch to monitor state change of the instance , in place of InstanceId as shown below.

Answer 1

No, there is no direct integration between Cloudwatch Event Rules and the SSM Parameter Store.

You'll have to build some automation to update the rule yourself. The goto solution for this would be a Lambda function that responds to changes in the parameter value and then updates the rule with the value. To trigger this you should be able to use an advanced parameter and use event bridge to trigger the lambda on parameter value changes.
