How to get multiple values from remote machine (Invoke-Command)

[kolaborek08]

Hello,

I try to make script to inventory my computers in LAN. I wrote script to get processor, RAM and HDD values:

PowerShell

$computerNames = ("computer1", "computer2", "computer3") $sessions = New-PSSession -ComputerName $computerNames -Credential (Get-Credential) $eeee = Invoke-Command -Session $sessions -ScriptBlock {    &{        $env:computername;         Get-CimInstance -ClassName Win32_Processor | Select-Object @{Name="Procesor"; Expression={$_.Name}};        Get-CimInstance -ClassName Win32_ComputerSystem | Select-Object @{Name="RAM"; Expression={$_.TotalPhysicalMemory / 1GB}};        Get-CimInstance -ClassName Win32_LogicalDisk -Filter "DriveType=3" | Select-Object @{Name="HDD"; Expression={$_.Size / 1GB}};    } }

1 2 3 4 5 6 7 8 9 10

$computerNames = ("computer1", "computer2", "computer3") $sessions = New-PSSession -ComputerName $computerNames -Credential (Get-Credential) $eeee = Invoke-Command -Session $sessions -ScriptBlock {    &{        $env:computername;         Get-CimInstance -ClassName Win32_Processor | Select-Object @{Name="Procesor"; Expression={$_.Name}};        Get-CimInstance -ClassName Win32_ComputerSystem | Select-Object @{Name="RAM"; Expression={$_.TotalPhysicalMemory / 1GB}};        Get-CimInstance -ClassName Win32_LogicalDisk -Filter "DriveType=3" | Select-Object @{Name="HDD"; Expression={$_.Size / 1GB}};    } }

But in result I don’t have all values what I want but only computer name, one value and RunSpaceID.

Procesor PSComputerName RunspaceId ——– ————– ———- Processor_name computer1 some_Runspace Processor_name computer2 some_Runspace Processor_name computer3 some_Runspace If I’ll comment line responsible for getting processor value from computer then RAM value will appear. The same is with HDD. But how can I make to get all this values at one time? Best Regards Daniel

Hello kolaborek08,

Inside your Script block you need to create PSCustom object and return it.

PowerShell

$InventoryObject=[PSCustom Object]@{ ComputerName = $env:computername; Procesor = $(Get-CimInstance -ClassName Win32_Processor | Select-Object -ExpandProperty Name); RAM=$(Get-CimInstance -ClassName Win32_ComputerSystem | Select-Object -ExpandProperty TotalPhysicalMemory)/ 1GB HDD=$(Get-CimInstance -ClassName Win32_LogicalDisk -Filter "DriveType=3" | Select-Object -ExpandProperty Size) / 1GB; } $InventoryObject

1 2 3 4 5 6 7 8 9 10 11 12 13

$InventoryObject=[PSCustom Object]@{   ComputerName = $env:computername;   Procesor = $(Get-CimInstance -ClassName Win32_Processor | Select-Object -ExpandProperty Name);   RAM=$(Get-CimInstance -ClassName Win32_ComputerSystem | Select-Object -ExpandProperty TotalPhysicalMemory)/ 1GB   HDD=$(Get-CimInstance -ClassName Win32_LogicalDisk -Filter "DriveType=3" | Select-Object -ExpandProperty Size) / 1GB;   }   $InventoryObject

Reference: https://docs.microsoft.com/en-us/powershell/scripting/learn/deep-dives/everything-about-pscustomobject?view=powershell-7

Right now you are returning only remote computer name.

Hope that helps.

PowerShell

$computerNames = ("computer1", "computer2", "computer3") $sessions = New-PSSession -ComputerName $computerNames -Credential (Get-Credential) $result = Invoke-Command -Session $sessions -ScriptBlock { $proc = (Get-CimInstance -ClassName Win32_Processor).Name $ram = (Get-CimInstance -ClassName Win32_ComputerSystem).TotalPhysicalMemory $hdd = (Get-CimInstance -ClassName Win32_LogicalDisk -Filter "DriveType=3").Size # hard drive and ram sizes will be listed with 2 decimal places [PSCustomObject]@{ Processor = $proc RAM = $ram = "{0:n2} GB" -f ($ram /1GB) HDD = $hdd | ForEach-Object {"{0:n2} GB" -f ($_ /1GB)} } }

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15

$computerNames = ("computer1", "computer2", "computer3") $sessions = New-PSSession -ComputerName $computerNames -Credential (Get-Credential)   $result = Invoke-Command -Session $sessions -ScriptBlock {         $proc = (Get-CimInstance -ClassName Win32_Processor).Name     $ram = (Get-CimInstance -ClassName Win32_ComputerSystem).TotalPhysicalMemory     $hdd = (Get-CimInstance -ClassName Win32_LogicalDisk -Filter "DriveType=3").Size # hard drive and ram sizes will be listed with 2 decimal places     [PSCustomObject]@{         Processor = $proc         RAM = $ram = "{0:n2} GB" -f ($ram /1GB)         HDD = $hdd | ForEach-Object {"{0:n2} GB" -f ($_ /1GB)}       } }
