# `CreateGroup` 搭配 AWS SDK 或 CLI 使用
<a name="xray_example_xray_CreateGroup_section"></a>

下列程式碼範例示範如何使用 `CreateGroup`。

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

**AWS CLI**  
**建立群組**  
下列 `create-group` 範例建立名為 `AdminGroup` 的群組資源。群組會取得篩選條件表達式，將群組的條件定義為與特定服務相關的區段，導致發生故障或錯誤。  

```
aws xray create-group \
   --group-name {{"AdminGroup"}} \
   --filter-expression "service(\"mydomain.com\") {fault OR error}"
```
輸出：  

```
{
    "GroupName": "AdminGroup",
    "GroupARN": "arn:aws:xray:us-west-2:123456789012:group/AdminGroup/123456789",
    "FilterExpression": "service(\"mydomain.com\") {fault OR error}"
}
```
