Is there someway to record Task Managers info about CPU and memory usage to examine later? Or an equivalent tool?

  • Now in 2020, win10 Task Manager got [App history] tab showing seeming actual CPU time/cycle usage (whereas procexp CPU time column seems more like time since process start)

Windows Performance Monitor (perfmon) should do the job for you; you can configure it to log to a file, so just enable the counters you need and it'll log as much as you want.

  • Start > Run > perfmon
  • Hit the plus sign next to Performance Logs and Alerts
  • Right click System Log and select properties.
  • Adjust the sampling times to whatever you like
  • When you are done, hit OK then the plus sign at the top of the window.

    I don't see a "Performance Logs and Alerts" section on Windows 10.

  • To collect the required Perfmon log data in Windows 7, Windows Server 2008 R2, Windows 8, Windows 2012 and Windows Vista: Click Start > Run, enter perfmon.exe, and click OK. Go to the User Defined folder. Click New > Data Collector Set. Enter a name for your Data Collector Set. kb.vmware.com/s/article/2010970

I use PolyMon to monitor these kinds of things. You can define various "alert" conditions about which you'd like to receive notification, so I get notified if one of my servers is having a problem.

But it also stores all these results in a long term database, so I can look back at the memory usage of server "X" and see it's memory usage trends over the last N days/weeks/months/years.



You may consider using a monitoring solution like zabbix, zenoss to collect and analyse your perf counters.


Cacti is a great webv based graphing programme. It can graph CPU, memory, disk space, etc, etc. It can also be extended with your own plugins.


Process Explorer will also show CPU history.


Yes, perfmon ("Performance Monitor" in Control Panel)
