Azure 数据湖一代。 2 (adls2), api 获取存储在数据湖中的数据的总体大小

Question

我正在寻找一种方法来获取有关存储在数据湖（天蓝色数据湖 gen2 2 - adls2）中的所有数据的总体大小的数据。 有谁知道如何获取有关数据湖大小（存储多少数据）的此类信息？ 试图找到合适的 API 但到目前为止没有找到任何东西。 将感谢任何提示。

Answer 1

如果您想获取存储在数据湖 gen2 中的所有数据的大小（不包括File, Table, Queue存储），您可以使用此Metrics - List REST API 与metricnames=BlobCapacity ，指定最近一小时的timespan ，例如，现在是2019-10-14T05:48:03Z ，只需使用timespan=2019-10-14T04:47:03Z/2019-10-14T05:47:03Z ，它在我这边工作正常。

样品：

GET https://management.azure.com/subscriptions/<subscription-id>/resourceGroups/<resource-group-name>/providers/Microsoft.Storage/storageAccounts/<storageaccount-name>/blobServices/default/providers/microsoft.insights/metrics?timespan=2019-10-14T04:47:03Z/2019-10-14T05:47:03Z&metricnames=BlobCapacity&api-version=2018-01-01

      { 
         "id":"/subscriptions/xxxxxxx/resourceGroups/xxxxxxx/providers/Microsoft.Storage/storageAccounts/joygen2/blobServices/default/providers/Microsoft.Insights/metrics/BlobCapacity",
         "type":"Microsoft.Insights/metrics",
         "name":{ 
            "value":"BlobCapacity",
            "localizedValue":"Blob Capacity"
         },
         "displayDescription":"The amount of storage used by the storage account’s Blob service in bytes.",
         "unit":"Bytes",
         "timeseries":[ 
            { 
               "metadatavalues":[ 

               ],
               "data":[ 
                  { 
                     "timeStamp":"2019-10-14T04:47:00Z",
                     "average":44710.0
                  }
               ]
            }
         ]
      }
   ],
   "namespace":"Microsoft.Storage/storageAccounts/blobServices",
   "resourceregion":"eastus"
}

更新：

如果要获取所有数据的大小，包括File, Table, Queue存储，只需使用UsedCapacity指标名称。

样品：

GET https://management.azure.com/subscriptions/<subscription-id>/resourceGroups/<resource-group-name>/providers/Microsoft.Storage/storageAccounts/<storageaccount-name>/providers/microsoft.insights/metrics?timespan=2019-10-14T04:47:03Z/2019-10-14T05:47:03Z&metricnames=UsedCapacity&api-version=2018-01-01
