Monitor the performance of individual window service

Question

I have 7 windows services. i want to monitor the performance of the individual services like the processor usage, memory usage etc.

If i use perfmon, it gives for the entire system but not the individual services. Can anyone please suggest how do i monitor the performance of individual services?

Answer 1

Perfmon can monitor individual processes! Just chose process in "Add counters/Performance objects" combo. For "quick" monitoring I have found that Sysinternals (now Microsoft) Process Explorer is easy and nice. Some services give you performance information (available by sockets/files etc) that can be displayed by tools such as MRTG or Cacti.

To check the memory of individual services, you will have to change the service types to "Own Process". This Gist show the complete code. The central idea is trying to change the service type from the least intrusive to the most intrusive way:

$win32Service = Get-CimInstance -ClassName Win32_Service -Filter "Name = '$ServiceName'" -Verbose:$false

if ($win32Service)
{
    if (!(Set-ServiceTypeToOwnProcessByCim $win32Service))
    {
        if (!(Set-ServiceTypeToOwnProcessByWindowsRegistry $win32Service))
        {
            if (Grant-FullControlRightsOnServiceRegistryKeyToCurrentUser $win32Service)
            {
                Set-ServiceTypeToOwnProcessByWindowsRegistry $win32Service | Out-Null
            }
        }
    }
}
else
{
    Write-Warning "[$ServiceName] Service not found"
}

When putting the Set-ServiceTypeToOwnProcess.ps1 and Enable-Privilege.ps1 files in the same folder, you can execute the script like this:

.\Set-ServiceTypeToOwnProcess.ps1 -ServiceName 'Appinfo', 'gpsvc', 'Schedule', 'SENS', 'SessionEnv', 'wuauserv'
