Missing Performance Counters Alarm

The Missing Performance Counters alarm becomes active when performance counter data is unavailable. This may occur when:

• The machine is unusually busy, or
• The performance counter has been disabled.

To verify the performance counters are unavailable, run Microsoft Performance Monitor and look for the Memory and Processor performance objects in the Add Counters dialog for the machine being diagnosed. If these objects are not listed then they need to be enabled. To do this (Windows 2003) use Exctrlst from Microsoft.

Run the utility and do the following:

1. Edit the Machine Name to show the name of the machine being diagnosed.
2. Click the Refresh button.
3. Select Service as the sort order.
4. Select PerfOS in the counter list.
5. Check the Performance Counters Enabled checkbox if unchecked.
6. Repeat steps 4–5 for the PerfDisk, PerfNet and PerfProc counters.
7. Restart the machine being diagnosed to enable the counters.
