Question

如果驱动器的可用空间是100％空闲并且我将最小阈值空间设置为25％，则脚本错误地报告驱动器低于阈值...意味着100＆lt; 25 虽然如果我要更换 $ FreePercent =“{0：N0}” - f（100 * $ objDisk.FreeSpace / $ objDisk.Size）with $ FreePercent =（100 * $ objDisk.FreeSpace / $ objDisk.Size）... 我得到了正确的结果。我如何解决四舍五入问题。这是我的代码

# For Loop -  get % free space of all drives
#Define Variables
$Notify = 0
$MinFreePercent = "25"
#$FileDriveSpace = "c:\temp\DriveSpace.txt"
$ComputerName = $(Get-WmiObject Win32_Computersystem).name
$OutArray = @()

$outarray += "Disk space Alerts and Utilizations on server $ComputerName"
$AllDisks = get-wmiobject Win32_LogicalDisk -Filter “DriveType = 3"
#Omit the a, b drives if exist
$AllDisks = $AllDisks | ? { $_.DeviceID -notmatch "[ab]:"}
foreach ($objdisk in $AllDisks) 
{ 
   #$FreePercent = "{0:P0} " -f ($objDisk.FreeSpace/$objDisk.Size) 
   $FreePercent = "{0:N0}" -f (100 * $objDisk.FreeSpace/$objDisk.Size) 


   If ($FreePercent -lt $MinFreePercent) 
      { 
        $Threshold = "Threshold Reached" 
        $Notify = 1
      }
   Else
      { $Threshold = "N/A"}

   $DeviceId = $objDisk.DeviceID
   $myobj = "" | Select "Drive","PercentFreeSpace", "Threshold"
   $myobj.Drive = $DeviceId
   $myobj.PercentFreeSpace = $FreePercent
   $myobj.Threshold = $Threshold

   $outLine = $DeviceId + " " + $FreePercent + " " + $Threshold + " " + $MinFreePercent
   $outLine

   #Add the object to the out-array
   $outarray += $myobj
   #Wipe the object just to be sure
   $myobj = $null
}

所以这里的问题是-f或格式化运算符。它将你的超级驱动器百分比免费[int]并将其变成一个普通的无聊[string]。我个人使用[math]加速器并调用圆方法。

[math]::Round($mynumber,0)

您还可以通过在technet库中查找此类事物来节省一些时间： http://gallery.technet.microsoft.com/Get-HardDrive-0eef638f

我不记得该版本是否将数据作为字符串或整数返回，但您会看到一个圆形方法的示例。

使用PowerShell返回服务器上所有驱动器的可用空间
