# 在 中設定 DescribeDetector API AWS IoT Events
<a name="iotevents-commented-example-describe-detector"></a>

中的 `DescribeDetector` API AWS IoT Events 可讓您擷取特定偵測器執行個體的詳細資訊。此操作提供偵測器目前狀態、變數值和作用中計時器的洞見。透過使用此 API，您可以監控 AWS IoT Events 偵測器的即時狀態，促進 IoT 事件處理工作流程的偵錯、分析和管理。

CLI 命令：

```
aws iotevents-data describe-detector --detector-model-name areaDetectorModel --key-value Area51
```
