It uses the Win32_OperatingSystem class from the CIM repository to get the last boot up time of each computer and calculates the uptime based on the current date and time. The function returns the uptime in months, weeks, days, hours, and minutes. .PARAMETER ComputerName -ComputerName <String[]> Specifies the name(s) of the remote computer(s) for which to retrieve the system uptime. .EXAMPLE Get-SysUptime -ComputerName "Server01" Retrieves the system uptime of the remote computer named "Server01" and displays it in months, weeks, days, hours, and minutes. .EXAMPLE "Server01", "Server02" | Get-SysUptime Retrieves the system uptime of the remote computers named "Server01" and "Server02" and displays it in months, weeks, days, hours, and minutes. .NOTES To use this function, you need to have administrative privileges on the remote computers. If there is an error retrieving the uptime of a particular computer, the function throws a terminating error and displays an error message. .LINK Author: Luis Carrillo GitHub: https://www.github.com/LuisCarrilloTech #> [CmdletBinding()] param ( [Parameter(Mandatory = $true, ValueFromPipeline = $true, ValueFromPipelineByPropertyName = $true, Position = 0)] [String[]]$ComputerName ) foreach ($Computer in $ComputerName) { try { $sys = Get-CimInstance -ClassName Win32_OperatingSystem -ComputerName $Computer -ErrorAction Stop $time = New-TimeSpan -Start $sys.LastBootUpTime -End (Get-Date) [PSCustomObject]@{ ComputerName = $Computer "Months" = $time.Days / 30.4375 "Weeks" = $time.Days / 7 "Days" = $time.Days "Hours" = $time.Hours "Minutes" = $time.Minutes } } catch { Write-Error -Message "Error gathering uptime for system $Computer" Write-Output $_.Exception.Message } } } |
