Formatting multiple result sets together in powershell - powershell

Question

Get-WmiObject -Class Win32_OperatingSystem -ComputerName (Get-Content "C:\Temp\Servers.txt") | SELECT-Object PSComputerName, #{Name="Memory (RAM in GB)";Expression={[Math]::Round($_.TotalVisibleMemorySize/1024/1024)}} | Format-Table
Get-WmiObject -Class Win32_logicaldisk -ComputerName (Get-Content "C:\Temp\Servers.txt") | Select-Object PSComputerName, DriveType, DeviceID, VolumeName, #{Name="Size";Expression={[math]::ceiling($_.Size /1GB)}} , #{Name="FreeSpace";Expression={[math]::ceiling($_.FreeSpace /1GB)}}, Compressed | where DriveType -eq 3 | Format-Table
Get-WmiObject -Class Win32_OperatingSystem -ComputerName (Get-Content "C:\Temp\Servers.txt")| Select-Object PSComputerName, BuildNumber, BuildType, Caption, CodeSet, OSArchitecture, SystemDrive, TotalVisibleMemorySize, Version | Format-Table
Get-WmiObject -Class win32_product -ComputerName (Get-Content "C:\Temp\Servers.txt") | Select-Object Name, Version, Vendor, InstallDate | Format-Table
Get-WmiObject -Class Win32_Service -ComputerName (Get-Content "C:\Temp\Servers.txt") | Select-Object PSComputerName, DisplayName, StartName, PathName, StartMode| where DisplayName -Like "*xyz*" |Format-Table
I have till now managed to piece together the above to get the information I need from serveral servers, however now I want to format it so that I can collate information for each server in a format that I can display
for eg.
Server : ABC
RAM : 64 GB
Number of Processors : 8
Disk :
Table of disk Sizes Etc
Any pointers would be appreciated

With all these properties, you would get a nested object array, which probably is easiest to view in JSON format.
I have changed all Get-WmiObject into the newer and faster Get-CimInstance cmdlets below
$result = Get-Content "C:\Temp\Servers.txt" | ForEach-Object {
# create an ordered hashtable to store the results for each server
$pcinfo = [ordered]#{}
# System info
$data = Get-CimInstance -ClassName Win32_ComputerSystem -ComputerName $_
$pcinfo['Computer'] = $data.PSComputerName
$pcinfo['Memory (RAM in GB)'] = '{0:N2}' -f ($data.TotalPhysicalMemory / 1GB)
# OS info
$data = Get-CimInstance -ClassName Win32_OperatingSystem -ComputerName $_
$pcinfo['BuildNumber'] = $data.BuildNumber
$pcinfo['BuildType'] = $data.BuildType
$pcinfo['Caption'] = $data.Caption
$pcinfo['CodeSet'] = $data.CodeSet
$pcinfo['OSArchitecture'] = $data.OSArchitecture
$pcinfo['SystemDrive'] = $data.SystemDrive
$pcinfo['TotalVisibleMemorySize'] = $data.TotalVisibleMemorySize
$pcinfo['Version'] = $data.Version
# Product info (array of objects)
$pcinfo['Products'] = Get-CimInstance -ClassName Win32_Product -ComputerName $_ |
Select-Object Name, Version, Vendor, InstallDate
# Local fixed disk info (array of objects)
$pcinfo['FixedDrives'] = Get-CimInstance -ClassName Win32_LogicalDisk -ComputerName $_ -Filter 'DriveType=3' |
Sort-Object DeviceID |
Select-Object DriveType, DeviceID, VolumeName,
#{Name="Size";Expression={"{0:N2} GB" -f ($_.Size / 1GB)}},
#{Name="FreeSpace";Expression={"{0:N2} GB" -f ($_.FreeSpace / 1GB)}},
Compressed
# Services info (array of objects)
$pcinfo['Services'] = Get-CimInstance -ClassName Win32_Service -ComputerName $_ |
Where-Object { $_.DisplayName -like '*Adobe*' } |
Select-Object DisplayName, StartName, PathName, StartMode
# convert the hashtable to PSObject and output
[PsCustomObject]$pcinfo
}
# output the whole structure as JSON for easier reading and optionally save it to file
$result | ConvertTo-Json -Depth 3 # | Set-Content -Path 'Path\To\Output.json' -Force
