Powershelll script to get server status and disk space details using invoke command parallely

Question

I want to perform disk cleanup on 500 VDIs using below script and create a proper report with VDI status(online or offline) and disk space detail using below script .But here Iam not using for each loop as I want to run cleanup parallel on VDIs .If any VDI is offline or winRM not enabled the script will throw error for that VDIs ,I want to catch those VDI and put in report if they are offline or any other winrm error .I can get disk space detail for online VDI but how to get offline or error VDI status in report ???????

$AllVDI = get-content "list for500 vDI "
$Space= Invoke-Command -ComputerName $AllVDI -ScriptBlock {
Remove-Item -Path "C:\Windows\Temp*" -Recurse -Force
Get-WmiObject Win32_LogicalDisk -Filter "DeviceID='C:'"
}
$Space|select systemname,drive,freespace|export.csv "C:\report"

Give this a try:

$OnlineMachines = @()
$OffLineMachines = @()
$Machines = get-content c:\junk\servers.txt
$Report = @()
[array]$OnlineMachines = Test-Connection -ComputerName $machines -ErrorAction SilentlyContinue -WarningAction SilentlyContinue |
                    Select-Object -Expand Address |
                        Sort-Object -Unique
$Machines |
    ForEach-Object{
        if ($OnlineMachines -notcontains $_){
            $OffLineMachines += $_
        }
    }
$Space = Invoke-Command -ComputerName $OnlineMachines -ScriptBlock{
                Remove-Item -Path "C:\Windows\Temp*" -Recurse -Force
                Get-WmiObject Win32_LogicalDisk -Filter "DeviceID='C:'"
            } |
$Space |
    ForEach-Object{
        $Report += [PSCustomObject]@{
                        Status = 'Online'
                        SystemName = $_.systemname
                        Drive = $_.drive
                        FreeSpace = $_.freespace
                    }
    }
$OffLineMachines |
    ForEach-Object{
        $Report += [PSCustomObject]@{
            Status = "Unavailable: Ping or WSMan failed"
            SystemName = "N/A"
            Drive = "N/A"
            FreeSpace = "N/A"
        }
    }
$Report |
    Export-CSV "C:\report\Space.CSV"

Hi Rich , One query .I have one terminal server from where all my VDIs are reachable and I am connecting this terminal using invoke-command from my management server but here in report I am not getting freespace and C:# drive name for VDIs iam getting field as NA in report .I have used the below code .But when I ran directly on MyTerminalServer I am getting proper report .

Invoke-command -computername "MyTerminalServer" -scriptblock  {

$OnlineMachines = @()
 $OffLineMachines = @()
 $Machines = get-content c:\junk\servers.txt
 $Report = @()
 [array]$OnlineMachines = Test-Connection -ComputerName $machines -ErrorAction SilentlyContinue -WarningAction SilentlyContinue |
                     Select-Object -Expand Address |
                         Sort-Object -Unique
 $Machines |
     ForEach-Object{
         if ($OnlineMachines -notcontains $_){
             $OffLineMachines += $_
         }
     }
 $Space = Invoke-Command -ComputerName $OnlineMachines -ScriptBlock{
                 Remove-Item -Path "C:\Windows\Temp*" -Recurse -Force
                 Get-WmiObject Win32_LogicalDisk -Filter "DeviceID='C:'"
             } |
 $Space |
     ForEach-Object{
         $Report += [PSCustomObject]@{
                         Status = 'Online'
                         SystemName = $_.systemname
                         Drive = $_.drive
                         FreeSpace = $_.freespace
                     }
     }
 $OffLineMachines |
     ForEach-Object{
         $Report += [PSCustomObject]@{
             Status = "Unavailable: Ping or WSMan failed"
             SystemName = "N/A"
             Drive = "N/A"
             FreeSpace = "N/A"
         }
     }
 $Report |
     Export-CSV "C:\report\Space.CSV"

   }
