# `DeleteSamplingRule` 搭配 AWS SDK 或 CLI 使用
<a name="xray_example_xray_DeleteSamplingRule_section"></a>

下列程式碼範例示範如何使用 `DeleteSamplingRule`。

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

**AWS CLI**  
**刪除取樣規則**  
以下 `delete-sampling-rule` 範例會刪除指定的取樣規則。您可以使用群組名稱或群組 ARN 來指定群組。  

```
aws xray delete-sampling-rule \
    --rule-name {{polling-scorekeep}}
```
輸出：  

```
{
    "SamplingRuleRecord": {
        "SamplingRule": {
            "RuleName": "polling-scorekeep",
            "RuleARN": "arn:aws:xray:us-west-2:123456789012:sampling-rule/polling-scorekeep",
            "ResourceARN": "*",
            "Priority": 5000,
            "FixedRate": 0.003,
            "ReservoirSize": 0,
            "ServiceName": "Scorekeep",
            "ServiceType": "*",
            "Host": "*",
            "HTTPMethod": "GET",
            "URLPath": "/api/state/*",
            "Version": 1,
            "Attributes": {}
        },
        "CreatedAt": 1530574399.0,
        "ModifiedAt": 1530574399.0
    }
}
```
