#### [ CLI ]

**AWS CLI**  
**To disable detailed monitoring for an instance**  
This example command disables detailed monitoring for the specified instance.  
Command:  

```
aws ec2 unmonitor-instances --instance-ids i-1234567890abcdef0
```
Output:  

```
{
  "InstanceMonitorings": [
      {
          "InstanceId": "i-1234567890abcdef0",
          "Monitoring": {
              "State": "disabling"
          }
      }
  ]
}
