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

以下代码示例演示如何使用 `CreateGroup`。

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

**AWS CLI**  
**创建组**  
以下 `create-group` 示例创建一个名为 `AdminGroup` 的组资源。该组将获得一个筛选表达式，以便将组标准定义为与导致故障或错误的特定服务相关的分段。  

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

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