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

Process Explorer will also show CPU history.

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.
