Close other applications collecting performance counters

Only one application at a time can collect disk performance counters. Data collection failed because another application was collecting one or more disk counters.

If you are viewing real-time data in Windows Reliability and Performance Monitor using Performance Monitor or Resource Monitor, it will interfere with scheduled data collection. Stop Resource Monitor or remove the affected counters from the Performance Monitor view to resolve the error.

To stop Resource Monitor:

  • In the Resource Monitor window, click the Stop button.

To remove a counter from the Performance Monitor view:

  1. In Performance Monitor, right-click the graph display area and then click Properties.
  2. On the Data tab, in Counters, click the name of the counter you want to remove, and then click Remove.
  3. Click OK to close Performance Monitor Properties.


You can use Windows Reliability and Performance Monitor to verify that netowkr performance counters are properly collected and displayed in a Performance Monitor graph. In addition, you can use the typeperf command to get a list of the available counters on the local system.

Membership in the local Administrators group is required to complete these procedures.
