Question

我正在寻找一种获取有关存储在数据湖（azure数据湖gen2 2-adls2）中的所有数据的整体大小的数据的方法。有谁知道如何获取有关数据湖大小的信息（存储了多少数据）？试图找到合适的API，但到目前为止没有找到任何东西。感谢您提供的任何提示。

Answer 1

如果要获取存储在数据湖gen2中的所有数据的大小（不包括File, Table, Queue存储），可以将此Metrics - List REST API与metricnames=BlobCapacity一起使用，指定最近一个小时的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，它对我来说效果很好。

示例：

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

响应：

 { 
   "cost":0,
   "timespan":"2019-10-14T04:47:03Z/2019-10-14T05:47:03Z",
   "interval":"PT1H",
   "value":[ 
      { 
         "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：

如果要获取包括File, Table, Queue存储在内的所有数据的大小，只需使用UsedCapacity度量标准名称即可。

示例：

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

响应：

   "cost":0,
   "timespan":"2019-10-14T04:47:03Z/2019-10-14T05:47:03Z",
   "interval":"PT1H",
   "value":[ 
      { 
         "id":"/subscriptions/xxxxx/resourceGroups/xxxxx/providers/Microsoft.Storage/storageAccounts/xxxxx/providers/Microsoft.Insights/metrics/UsedCapacity",
         "type":"Microsoft.Insights/metrics",
         "name":{ 
            "value":"UsedCapacity",
            "localizedValue":"Used capacity"
         },
         "displayDescription":"Account used capacity",
         "unit":"Bytes",
         "timeseries":[ 
            { 
               "metadatavalues":[ 

               ],
               "data":[ 
                  { 
                     "timeStamp":"2019-10-14T04:47:00Z",
                     "average":2559131.0
                  }
               ]
            }
         ]
      }
   ],
