# 检查 DynamoDB 表的当前热吞吐量
<a name="check-warm-throughput"></a>

使用以下 Amazon CLI 和 Amazon 管理控制台说明来检查表或索引的当前热吞吐量值。

## Amazon Web Services 管理控制台
<a name="warm-throughput-check-console"></a>

要使用 DynamoDB 控制台检查 DynamoDB 表的热吞吐量，请执行以下操作：

1. 登录 Amazon Web Services 管理控制台，并打开 DynamoDB 控制台：[https://console.aws.amazon.com/dynamodb/](https://console.amazonaws.cn/dynamodb/)。

1. 在左侧导航窗格中，选择 表。

1. 在**表**页面上，选择所需的表。

1. 选择**其它设置**以查看您当前的热吞吐量值。此值显示为每秒读取单位数和每秒写入单位数。

## Amazon CLI

以下 Amazon CLI 示例向您展示如何检查 DynamoDB 表的热吞吐量。

1. 对 DynamoDB 表运行 `describe-table` 操作。

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

1. 您将收到与以下内容类似的响应。您的 `WarmThroughput` 设置将显示为 `ReadUnitsPerSecond` 和 `WriteUnitsPerSecond`。当热吞吐量值正在更新时，`Status` 将为 `UPDATING`，当设置了新的热吞吐量值时，则为 `ACTIVE`。
