如何使用Powershell从Active Directory上的计算机获取磁盘信息

Question

我具有PowerShell的基本知识，并且得到了一个项目，该项目需要我创建一个PowerShell脚本，该脚本将域中的所有计算机都放在活动目录中，并收集每台计算机的可用空间/已用空间。

This is what I use in order to get servers with low disk space:

Import-Module ActiveDirectory

$Servers = Get-ADcomputer -Filter {OperatingSystem -like "*Server*"} -Properties Name, OperatingSystem -SearchBase "DC=yourDN,DC=local" | Select Name
$diskReport = Foreach($Server in $Servers)
{

    #$Status = "Offline"    
    $Name = $Server.Name
    #Make sure server is online
    if(Test-Connection -ComputerName $Name -ErrorAction SilentlyContinue)
    {

        #Get only 10%       
        Get-WMIObject win32_logicaldisk -ComputerName $Name -Filter "DriveType=3" -ErrorAction SilentlyContinue | Where-Object {   ($_.freespace/$_.size) -le '0.1'}        
    }
    else
    {
        #Server is offline
    }       

}

$lowservers = $diskreport | Select-Object @{Label = "Server Name";Expression = {$_.SystemName}},
        @{Label = "Drive Letter";Expression = {$_.DeviceID}},
        @{Label = "Total Capacity (GB)";Expression = {"{0:N1}" -f( $_.Size / 1gb)}},
        @{Label = "Free Space (GB)";Expression = {"{0:N1}" -f( $_.Freespace / 1gb ) }},
        @{Label = 'Free Space (%)'; Expression = {"{0:P0}" -f ($_.freespace/$_.size)}} 

This will first pull all your objects using Get-ADComputer. Then it just does a simple foreach to put everything into $diskReport. The $lowservers is just to clean it up a bit.

You can do whatever you want with $lowservers. I have mine on a scheduled task to run every Monday and Friday. Then send out an email if it finds something low.
