# 檢查 DynamoDB 資料表的目前暖輸送量
<a name="check-warm-throughput"></a>

使用下列 AWS CLI 和 AWS 主控台指示來檢查資料表或索引目前的暖輸送量值。

## AWS 管理主控台
<a name="warm-throughput-check-console"></a>

若要透過 DynamoDB 主控台檢查 DynamoDB 資料表的暖輸送量：

1. 登入 AWS 管理主控台 ，並在 https：//[https://console.aws.amazon.com/dynamodb/](https://console.aws.amazon.com/dynamodb/) 開啟 DynamoDB 主控台。

1. 在左側導覽窗格中，選擇 Tables (資料表)。

1. 在**資料表**頁面上，選取目標資料表。

1. 選取**其他設定**以檢視目前的暖輸送量值。此值顯示為每秒讀取單位與每秒寫入單位。

## AWS CLI
<a name="warm-throughput-check-CLI"></a>

下列 AWS CLI 範例示範如何檢查 DynamoDB 資料表的暖輸送量。

1. 在 DynamoDB 資料表上執行 `describe-table` 操作。

   ```
   aws dynamodb describe-table --table-name GameScores
   ```

1. 系統會傳回類似下列的回應。`WarmThroughput` 設定會顯示為 `ReadUnitsPerSecond` 和 `WriteUnitsPerSecond`。當暖輸送量值正在更新時，`Status` 會顯示為 `UPDATING`；當設定完成後，則顯示為 `ACTIVE`。
