Reboot time in seconds or minutes - Windows server

PowerShell Help
15

In which way are you scripting this? I’ve confirmed powershell’s Restart-Computer, shutdown.exe, and scheduled task all result in the eventlog entries. That is a function of windows itself when gracefully shutting down and start. I would assume you have a configuration issue or maybe filtering these out if you can’t see them/they aren’t created. On all normally functioning Windows machines, the following code will measure the reboot time in seconds based on the 6005/6006 eventlog entries.

$params = @{
    FilterHashtable = @{
        Logname      = 'System'
        ID           = 6005,6006
        ProviderName = 'Eventlog'
    }

    Oldest = $true
}

switch (Get-WinEvent @params){
    {$_.id -eq 6005} {
        
        if(!$stopped){            
            $stopped = 'No related shutdown event found'
            $total = 'N/A'
        }
        else{
            [float]$total = "{0:n2}" -f ($_.timecreated - $stopped).totalseconds
        }

        [PSCustomObject]@{
            ShutdownTimestamp = $stopped
            StartupTimestamp  = $_.timecreated
            TotalSeconds      = $total
        }

        Remove-Variable started,stopped,total -ErrorAction SilentlyContinue
    }

    {$_.id -eq 6006} {
        $stopped = $_.timecreated
    }
}
