function Get-PspSysInfo { <# .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 create a CIM session to obtain information, but will revert to DCOM if CIM is not available. If there's already a CIM session available, this can also be used to obtain the data. .PARAMETER ComputerName Provide the computername(s) to query. This will create a new CIM session which will be removed once the information has been gathered. Default value is the local machine. .PARAMETER Credential Provide the credentials for the CIM session to be created if current credentials are not sufficient. .PARAMETER CimSession Provide the CIM session object to query if this is already available. Once the information has been gathered, the CIM session will remain available for further use. .EXAMPLE PS C:\> Get-PspSysInfo -ComputerName CONTOSO-SRV01,CONTOSO-SRV02 ComputerName Model SerialNumber CPUCores CPULogical MemoryGB ------------ ----- ------------ -------- ---------- -------- CONTOSO-SRV01 Virtual Machine 6656-6324-2091-0011-9109-1646-89 1 2 0 CONTOSO-SRV02 Virtual Machine 8945-5393-3426-8378-9495-3257-53 1 2 1 Gets the installed server roles for CONTOSO-SRV01 and CONTOSO-SRV02, displaying the default properties. .NOTES Name: Get-PspSysInfo.ps1 Author: Robert Prüst Module: PSP-Inventory DateCreated: 24-02-2019 DateModified: 12-03-2019 Blog: https://powershellpr0mpt.com .LINK https://powershellpr0mpt.com #> [OutputType('PSP.Inventory.SystemInfo')] [Cmdletbinding(DefaultParameterSetName = 'Computer')] param( [Parameter(Position = 0, ValueFromPipeline = $true, ValueFromPipelineByPropertyName = $true, ParameterSetName = 'Computer')] [ValidateNotNullorEmpty()] [Alias('CN')] [String[]]$ComputerName = $env:COMPUTERNAME, [Parameter(ParameterSetName = 'Computer')] [PSCredential]$Credential, [Parameter(Position = 0, ValueFromPipeline = $true, ParameterSetName = 'Session')] [Alias('Session')] [Microsoft.Management.Infrastructure.CimSession[]]$CimSession ) process { if ($PSCmdlet.ParameterSetName -eq 'Computer') { $CimSession = @() $CimProperties = @{ ErrorAction = 'Stop' Computername = '' } if ($credential.Username) { $CimProperties.Add('Credential', $Credential) } foreach ($Computer in $ComputerName) { $Computer = $Computer.toUpper() ` $CimProperties.ComputerName = $Computer Try { $CimSession += New-CimSession @CimProperties } catch [Microsoft.Management.Infrastructure.CimException] { Write-Warning "[$Computer] - does not have CIM access, reverting to DCOM instead" $CimOptions = New-CimSessionOption -Protocol DCOM $CimProperties.Add('SessionOption', $CimOptions) | Out-Null try { $CimSession += New-CimSession @CimProperties } catch { Write-Warning "[$Computer] - cannot be reached. $($_.Exception.Message)" } Finally { $CimProperties.Remove('SessionOption') | Out-Null } } Catch { Write-Warning "[$Computer] - cannot be reached. $($_.Exception.Message)" } } } foreach ($Session in $CimSession) { _GetSysInfo -Cimsession $Session } } End { if ($PSCmdlet.ParameterSetName -eq 'Computer' -AND $CimSession.count -gt 0) { Remove-Cimsession $CimSession } } } |
