# AWS API 用量指標
<a name="AWS-API-Usage-Metrics"></a>

大多數支援 AWS CloudTrail 記錄APIs 也會向 CloudWatch 報告用量指標。CloudWatch 中的 API 用量指標可讓您在 CloudWatch 主控台中視覺化指標、建立自訂儀表板、使用 CloudWatch 異常偵測偵測活動變更，以及設定警示，在用量接近閾值時發出警示，以主動管理 API 用量。

 可以參照下表了解會向 CloudWatch 報告 API 用量指標的服務。資料表列出用於 `Service` 維度的值，以便您查看該服務的用量指標。您可以依循本節中的程序來檢視向 CloudWatch 報告用量指標的服務 API 清單。

某些服務也會報告其他 API 的用量指標。若要查看 API 是否向 CloudWatch 報告用量指標，請使用 CloudWatch 主控台查看該服務在 `AWS/Usage` 命名空間中報告的指標。

**若要查看向 CloudWatch 報告用量指標的服務 API 清單**

1. 透過 [https://console.aws.amazon.com/cloudwatch/](https://console.aws.amazon.com/cloudwatch/) 開啟 CloudWatch 主控台。

1. 在導覽窗格中，選擇**指標**。

1. **在所有指標**索引標籤上，選擇**用量**，然後選擇**依 AWS 資源**。

1. 在指標清單附近的搜尋方塊中，輸入服務的名稱。指標會依您輸入的服務進行篩選。
