[Azure]使用Powershell统计经典存储账号下容器中Blob的使用情况

脚本比较简单，不做过多介绍，唯一需要注意的是考虑到存储账号下文件数量过多的情况（例如十万或者百万级的文件数），为了避免单次Query过多文件数导致卡死或者超时，因此脚本中使用了一个$tokenStop变量限制每次Query Blob的上线（脚本中定义的是5000一次，如果觉得有需要可以改成10000，不要太多）。

脚本如下：

param(      [Parameter(Mandatory = $true)]    [string]$SubscriptionName,       [Parameter(Mandatory = $true)]    [string]$StorageAccountName)Function SummarizeContainer($context, $containerName){    Write-Host ("Calculating container {0}" -f $containerName) -ForegroundColor Yellow;    $totalCount = 0;    $totalSize = 0;    $token = $null;    $tokenStep = 5000;    do    {        $blobs = Get-AzureStorageBlob -Container $containerName -Context $context -ContinuationToken $token -MaxCount $tokenStep;        if($blobs.Length -le 0)         {             break;        }        foreach($blob in $blobs)        {            $totalSize += $blob.Length;        }        $totalCount += $blobs.Count;        Write-Host ("{0} blobs calculated" -f $totalCount) -ForegroundColor Cyan;        $token = $blobs[$blobs.Count -1].ContinuationToken;    }    while($token -ne $null)    $totalSizeStr = "";    if (($totalSize/1024/1024/1024) -gt 1)    {        $totalSizeStr = "{0:N}GB" -f ($totalSize/1024/1024/1024);    }    elseif (($totalSize/1024/1024) -gt 1)    {        $totalSizeStr = "{0:N}MB" -f ($totalSize/1024/1024);    }    elseif (($totalSize/1024) -gt 1)    {        $totalSizeStr = "{0:N}KB" -f ($totalSize/1024);    }    else    {        $totalSizeStr = "{0:N}Byte" -f $totalSize;    }    return [PSCustomObject]@{ContainerName = $containerName                             BlobCount = $totalCount                             TotalSize = $totalSizeStr};}[void](Select-AzureSubscription -SubscriptionName $SubscriptionName);$storage = Get-AzureStorageAccount -StorageAccountName $StorageAccountName;$context = $storage.Context;Write-Host "Collecting containers" -ForegroundColor Yellow;$containers = Get-AzureStorageContainer -Context $context;$containerSummary = @();foreach ($container in $containers){    $containerSummary += (SummarizeContainer $context $container.Name);}$containerSummary | Select ContainerName, BlobCount, TotalSize;
