Azure 数据湖第 2 代 (adls2)，用于获取存储在数据湖中的数据的总体大小的 API

Question

我正在寻找一种方法来获取有关存储在数据湖(Azure Data Lake Gen2 2 - ADLS2(中存储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(存储了多少数据(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。 将不胜感激任何提示。

Answer 1

如果你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(，你可以用这个Metrics - ListREST API与metricnames=BlobCapacity一起使用，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。

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

{ 
"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指标名称。

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
