# 尋找具有先前設定之執行個體暖機時間的擴展政策
<a name="find-policies-with-a-previously-set-instance-warmup"></a>

若要識別您的政策是否有自己的 暖機時間`EstimatedInstanceWarmup`，請使用 執行下列 [describe-policies](https://awscli.amazonaws.com/v2/documentation/api/latest/reference/autoscaling/describe-policies.html) 命令 AWS CLI。將 {{my-asg}} 取代為您的 Auto Scaling 群組名稱。

```
aws autoscaling describe-policies --auto-scaling-group-name {{my-asg}}
  --query 'ScalingPolicies[?EstimatedInstanceWarmup!=`null`]'
```

以下為範例輸出。

```

    "PolicyName":"cpu50-target-tracking-scaling-policy",
