# 搭配使用 `DescribeScalableTargets` 與 CLI
<a name="example_application-auto-scaling_DescribeScalableTargets_section"></a>

下列程式碼範例示範如何使用 `DescribeScalableTargets`。

------
#### [ CLI ]

**AWS CLI**  
**描述可擴展的目標**  
下列 `describe-scalable-targets` 範例描述 `ecs` 服務命名空間的可擴展目標。  

```
aws application-autoscaling describe-scalable-targets \
    --service-namespace {{ecs}}
```
輸出：  

```
{
    "ScalableTargets": [
        {
            "ServiceNamespace": "ecs",
            "ScalableDimension": "ecs:service:DesiredCount",
            "ResourceId": "service/default/web-app",
            "MinCapacity": 1,
            "MaxCapacity": 10,
            "RoleARN": "arn:aws:iam::123456789012:role/aws-service-role/ecs.application-autoscaling.amazonaws.com/AWSServiceRoleForApplicationAutoScaling_ECSService",
            "CreationTime": 1462558906.199,
            "SuspendedState": {
                "DynamicScalingOutSuspended": false,
                "ScheduledScalingSuspended": false,
                "DynamicScalingInSuspended": false
            },
            "ScalableTargetARN": "arn:aws:application-autoscaling:us-west-2:123456789012:scalable-target/1234abcd56ab78cd901ef1234567890ab123"
        }
    ]
}
```
