Tracking CPU and Memory usage per process

Question

I suspect that one of my applications eats more CPU cycles than I want it to. The problem is - it happens in bursts, and just looking at the task manager doesn\'t help me as

Answer 1

You might want to have a look at Process Lasso.

Answer 2

There was a requirement to get status and cpu / memory usage of some specific windows servers. I used below script:

This is an example of Windows Search Service.

  $cpu = Get-WmiObject win32_processor
  $search = get-service "WSearch"
  if ($search.Status -eq 'Running')
  {
  $searchmem = Get-WmiObject Win32_Service -Filter "Name = 'WSearch'"
  $searchid = $searchmem.ProcessID
  $searchcpu1 = Get-WmiObject Win32_PerfRawData_PerfProc_Process | Where {$_.IDProcess -eq $searchid}
  Start-Sleep -Seconds 1
  $searchcpu2 = Get-WmiObject Win32_PerfRawData_PerfProc_Process | Where {$_.IDProcess -eq $searchid}
  $searchp2p1 = $searchcpu2.PercentProcessorTime - $searchcpu1.PercentProcessorTime
  $searcht2t1 = $searchcpu2.Timestamp_Sys100NS - $searchcpu1.Timestamp_Sys100NS
  $searchcpu = [Math]::Round(($searchp2p1 / $searcht2t1 * 100) /$cpu.NumberOfLogicalProcessors, 1)
  $searchmem = [Math]::Round($searchcpu1.WorkingSetPrivate / 1mb,1)
  Write-Host 'Service is' $search.Status', Memory consumed: '$searchmem' MB, CPU Usage: '$searchcpu' %'
  }

  else
  {
  Write-Host Service is $search.Status -BackgroundColor Red
  }

Hmm, I see that Process Explorer can do it, although its graphs are not too convenient. Still looking for alternative / better ways to do it.

WMI is Windows Management Instrumentation, and it's built into all recent versions of Windows. It allows you to programmatically track things like CPU usage, disk I/O, and memory usage.

Perfmon.exe is a GUI front-end to this interface, and can monitor a process, write information to a log, and allow you to analyze the log after the fact. It's not the world's most elegant program, but it does get the job done.
