Have you ever wondered why you DO see performance data in Windows 8/8.1 under the performance tab in Task Manager, but DON’T see this same information in Windows Server 2012/2012 R2?
Well I kind of missed seeing that information in Server but never really bothered to really investigate.
Windows Server 2012/2012 R2
I know the solution is too simple for words, but just in case you also forgot about this good old Diskperf command which you can run from an administrative command or Powershell prompt:
Diskperf –Y to switch on the Disk Performance counters. You don’t need an academic degree to figure out how to disable them again.
So much for an easy tip with great results.
