Automate EC2 into System Manager

Hello.

The AWS Config rule "ec2-instance-managed-by-systems-manager" may be helpful.
https://docs.aws.amazon.com/config/latest/developerguide/ec2-instance-managed-by-systems-manager.html

After creating a Config rule using this rule, I think it is possible to have EventBridge detect "complianceType" of "NON_COMPLIANT".
If you refer to the events in the document below, the event pattern will be as follows.

{
  "source": ["aws.config"],
  "detail-type": ["Config Rules Compliance Change"],
  "detail": {
    "messageType": ["ComplianceChangeNotification"],
    "configRuleName": ["ec2-instance-managed-by-systems-manager"],
    "newEvaluationResult": {
      "complianceType": ["NON_COMPLIANT"]
    }
  }
}
