## 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/).

```ts
declare const vpc: ec2.Vpc;
declare const instanceType: ec2.InstanceType;

new ec2.Instance(this, 'Instance1', {
vpc,
instanceType,
machineImage: new ec2.AmazonLinuxImage(),
detailedMonitoring: true,
});
```
