function Get-SysInfo { <# .SYNOPSIS Get System information for local or remote machines .DESCRIPTION Get System information for local or remote machines. Will query default information about the actual system, such as CPU & Memory and if it's virtual or physical Tries to use CIM to obtain information, but will revert to DCOM if CIM is not available .PARAMETER ComputerName Provide the computername(s) to query Default value is the local machine .EXAMPLE Get-SysInfo -ComputerName 'CONTOSO-SRV01','CONTOSO-WEB01' Description ----------- Gets the System information for CONTOSO-SRV01 and CONTOSO-WEB01 .NOTES Name: Get-SysInfo.ps1 Author: Robert Prüst Module: PSP-Inventory DateCreated: 24-02-2019 DateModified: 05-03-2019 Blog: https://powershellpr0mpt.com .LINK https://powershellpr0mpt.com #> [OutputType('PSP.Inventory.SystemInfo')] [Cmdletbinding()] param( [Parameter(Position = 0, ValueFromPipeline = $true, ValueFromPipelineByPropertyName = $true)] [ValidateNotNullorEmpty()] [String[]]$ComputerName = $env:COMPUTERNAME ) begin { [datetime]$InventoryDate = Get-Date } process { foreach ($Computer in $ComputerName) { $Computer = $Computer.ToUpper() try { $CS = Get-CimInstance -ClassName Win32_ComputerSystem -Property Manufacturer, Model, SystemType, NumberOfProcessors, NumberOfLogicalProcessors, TotalPhysicalMemory -ComputerName $Computer -ErrorAction Stop $Enclosure = Get-CimInstance -ClassName Win32_SystemEnclosure -Property SerialNumber, ChassisTypes, Description -ComputerName $Computer $BIOS = Get-CimInstance -ClassName Win32_Bios -Property Name, Manufacturer, SerialNumber, SMBIOSBIOSVersion -ComputerName $Computer $General = [PSCustomObject]@{ ComputerName = $Computer Manufacturer = $CS.Manufacturer Model = $CS.Model SystemType = $CS.SystemType State = if ($CS.Manufacturer -match "Hyper|Citrix|VMWare|virtual") {'Virtual'}else {'Physical'} SerialNumber = $Enclosure.SerialNumber ChassisType = (Convert-ChassisType $Enclosure.ChassisTypes) Description = $Enclosure.Description NumberofCores = $CS.NumberOfProcessors NumberOfLogicalProcessors = $CS.NumberOfLogicalProcessors TotalPhysicalMemoryGB = ([math]::round(($CS.TotalPhysicalMemory / 1GB), 0)) BIOSManufacturer = $BIOS.Manufacturer BIOSName = $BIOS.Name BIOSSerialNumber = $BIOS.SerialNumber BIOSVersion = $BIOS.SMBIOSBIOSVersion InventoryDate = $InventoryDate } $General.PSTypeNames.Insert(0, 'PSP.Inventory.SystemInfo') $General } catch [Microsoft.Management.Infrastructure.CimException] { Write-Warning "'$Computer' does not have CIM access, reverting to DCOM instead" $CimOptions = New-CimSessionOption -Protocol DCOM $CimSession = New-CimSession -ComputerName $Computer -SessionOption $CimOptions try { $CS = Get-CimInstance -CimSession $CimSession -ClassName Win32_ComputerSystem -Property Manufacturer, Model, SystemType, NumberOfProcessors, NumberOfLogicalProcessors, TotalPhysicalMemory -ErrorAction Stop $Enclosure = Get-CimInstance -CimSession $CimSession -ClassName Win32_SystemEnclosure -Property SerialNumber, ChassisTypes, Description $BIOS = Get-CimInstance -CimSession $CimSession -ClassName Win32_Bios -Property Name, Manufacturer, SerialNumber, SMBIOSBIOSVersion $General = [PSCustomObject]@{ ComputerName = $Computer Manufacturer = $CS.Manufacturer Model = $CS.Model SystemType = $CS.SystemType State = if ($CS.Manufacturer -match "Hyper|Citrix|VMWare|virtual") {'Virtual'}else {'Physical'} SerialNumber = $Enclosure.SerialNumber ChassisType = (Convert-ChassisType $Enclosure.ChassisTypes) Description = $Enclosure.Description NumberofCores = $CS.NumberOfProcessors NumberOfLogicalProcessors = $CS.NumberOfLogicalProcessors TotalPhysicalMemoryGB = ([math]::round(($CS.TotalPhysicalMemory / 1GB), 0)) BIOSManufacturer = $BIOS.Manufacturer BIOSName = $BIOS.Name BIOSSerialNumber = $BIOS.SerialNumber BIOSVersion = $BIOS.SMBIOSBIOSVersion InventoryDate = $InventoryDate } $General.PSTypeNames.Insert(0, 'PSP.Inventory.SystemInfo') $General } catch { Write-Warning "Unable to get WMI properties for computer '$Computer'" } } catch { Write-Warning "Unable to get WMI properties for computer '$Computer'" } } } } |
