Windows 2008 Perfmon Crashes - Reset User Defined Data Collector Sets
I discovered this very annoying bug in Windows Server 2008 when attempting to import an XML file with 100 servers
and counters in it.
No doubt one of the server had an issue and therefore and for some stupid reason, perfmon or Reliability And Performance Monitor, as its called now in 2008 is unable to handle this , and completely falls over.
Now, when you open Perfmon and try to view the User Defined Data Collector Sets, or run logman.exe from the command line, the application completely freezes and your unable to delete the corrupt dataset you just imported or even click elsewhere in the window.
In 2003, a reboot would fix this problem, but in 2008 it does not. The solution lies in the registry. Here’s how to fix the problem.
- Make sure your logged in as admin or with admin rights
- Close any open perfmon (Reliability and Performance Monitor) windows you have open.
- Click Start > Run then type regedit hit enter
- Goto: HKLM\Software\Microsoft\Windows NT\CurrentVersion\Schedule\TaskCache\Tree\Windows\PLA
-
You will see your Data Collector Sets in here, delete the one you created that caused the problem (or just delete them all if your not sure) **NOTE** Dont delete the “System” folder.
- Your done now, re-open perfmon, or logman and your problem should be solved.

Kill All Processes Of Certain Application In Unix/Linux
This is a very helpful command I use regularly.
If your like me, you open several instances of applications like “VI” and leave them in the background, most of the time without meaning to. Eventually you run a “PS -U” to view all your processes running and realize that theres 10 copies of the application running in the background which you havnt closed. Heres a command to quickly clear that up.
