# 什麼是 S3 Storage Lens 匯出資訊清單？
<a name="storage_lens_whatis_metrics_export_manifest"></a>

由於彙總了大量資料，一般用途儲存貯體中的 S3 Storage Lens 每日指標匯出可能會分割成多個檔案。資訊清單檔案 `manifest.json` 會描述當日指標匯出檔案的位置。每當傳送新的匯出時，都會隨附新的資訊清單。`manifest.json` 檔案內所包含的每個資訊清單檔案，都會提供匯出的中繼資料和其他基本資訊。

資訊清單資訊包含以下屬性：
+  `sourceAccountId`－組態擁有者的帳戶 ID。
+  `configId`－儀表板的唯一識別碼。
+  `destinationBucket`－指標匯出所放置之目的地儲存貯體的 Amazon Resource Name (ARN)。
+  `reportVersion`－匯出的版本。
+  `reportDate`－報告的日期。
+  `reportFormat`－報告的格式。
+  `reportSchema`－報告的結構描述。
+  `reportFiles`－目標儲存貯體中匯出報告檔案的實際清單。

您可以在 Amazon S3 主控台或使用 Amazon S3 REST API 和 SDKs AWS CLI，將指標匯出設定為儀表板組態的一部分而產生。
