+## Detailed Monitoring
+
+The following demonstrates how to enable [Detailed Monitoring](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/using-cloudwatch-new.html) for an EC2 instance. Keep in mind that Detailed Monitoring results in [additional charges](http://aws.amazon.com/cloudwatch/pricing/).

+  instanceType,
+  machineImage: new ec2.AmazonLinuxImage(),
