EC2 instance detailed CloudWatch monitoring should be enabled

  • Navigate to EC2.

  • In the left pane, select Instances.

  • Select the noncompliant instance.

  • Select Actions, CloudWatch Monitoring, Enable Detailed Monitoring.

  • In the Enable Detailed Monitoring dialog box, choose Yes, Enable.

  • Select Close.

  • To enable detailed monitoring, replace i-1234567890abcdef0 with your own instance ID:

    • aws ec2 monitor-instances --instance-ids i-1234567890abcdef0
