# 什么是 S3 Storage Lens 存储统计管理工具导出清单？
<a name="storage_lens_whatis_metrics_export_manifest"></a>

鉴于聚合的数据量大，在通用存储桶中，S3 Storage Lens 存储统计管理工具每日指标导出可以拆分为多个文件。清单文件 `manifest.json` 描述了当天的指标导出文件的位置。无论何时，只要传输了新的导出，就会附有新清单。`manifest.json` 文件中包含的每个清单均提供了有关导出的元数据和其他基本信息。

清单信息包括以下属性：
+ `sourceAccountId` – 配置拥有者的账户 ID。
+ `configId` – 控制面板的唯一标识符。
+ `destinationBucket` – 放置指标导出的目标桶 Amazon Resource Name（ARN）。
+ `reportVersion` – 导出的版本。
+ `reportDate` – 报告的日期。
+ `reportFormat` – 报告的格式。
+ `reportSchema` – 报告的架构。
+ `reportFiles` – 目标桶中的导出报告文件的实际列表。

清单目标路径示例：

```
user-defined-prefix/StorageLens/111122223333/example-dashboard-configuration-id/V_1/manifests/dt=2025-03-18/manifest.json
```

您可以将指标导出配置为作为控制面板配置的一部分在 Amazon S3 控制台中生成，也可以使用 Amazon S3 REST API、AWS CLI 和开发工具包进行生成。
