Powershell磁盘空间脚本

标签： powershell alert diskspace

I have a powershell script。简而言之，该脚本可以从多个服务器收集磁盘空间信息，并将其放入可通过邮件发送的.htm报告中。

现在，脚本会将磁盘信息收集到报告中，但我希望它只在其中一个磁盘的可用空间低于脚本中定义的临界值时发送电子邮件。

剧本：

# First lets create a text file, where we will later save the freedisk space info 
$freeSpaceFileName = "c:\disk_space.htm" 
$serverlist = "c:\sl.txt" 
$warning = 50 
$critical = 10 
New-Item $freeSpaceFileName -ItemType file -Force 
# Getting the freespace info using WMI 
#Get-WmiObject win32_logicaldisk  | Where-Object {$_.drivetype -eq 3} | format-table DeviceID, VolumeName,status,Size,FreeSpace | Out-File "C:\temp\FreeSpace.txt

我已经尝试添加某种IF，但它没有用，

感谢任何帮助。

我添加了几行代码来检查阈值，并仅在超过阈值时发送电子邮件。

$Threshold = 10GB; ########### Add this line
$ThresholdExceeded = $false; ############## Add this line

foreach ($server in Get-Content $serverlist) 
{ 
    Add-Content $freeSpaceFileName "<table width='100%'><tbody>" 
    Add-Content $freeSpaceFileName "<tr bgcolor='#CCCCCC'>" 
    Add-Content $freeSpaceFileName "<td width='100%' align='center' colSpan=6><font face='tahoma' color='#003399' size='2'><strong> $server </strong></font></td>" 
    Add-Content $freeSpaceFileName "</tr>" 

    writeTableHeader $freeSpaceFileName 

    $dp = Get-WmiObject win32_logicaldisk -ComputerName $server |  Where-Object {$_.drivetype -eq 3} 
    foreach ($item in $dp) 
    {
        ################ Add this next line
        if ($Item.FreeSpace -lt $Threshold) { $ThresholdExceeded = $true; };             Write-Host  $item.DeviceID  $item.VolumeName $item.FreeSpace $item.Size 
        writeDiskInfo $freeSpaceFileName $item.DeviceID $item.VolumeName $item.FreeSpace $item.Size 

    } 
}

################### Add this code
if ($ThresholdExceeded) {
    sendEmail cdarwin@evolve.com cdarwin@evolve.com "Disk Space Report - $Date" hub1 $freeSpaceFileName;
}
