#### [ CLI ]

**AWS CLI**  
**停用執行個體的詳細監控**  
這個範例命令會停用指定執行個體的詳細監控。  
命令：  

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

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