NT version error message

[ChoccyHobNob]

This happens every few seconds, pauses for 10 mins then happens every few seconds again...

2010-05-27 16:07:28: error:modules\CheckSystem\PDHCollector.cpp:208: Failed to query performance counters: \Processor(_total)\% Processor Time: PdhGetFormattedCounterValue failed: -2147481642: A counter with a negative denominator value was detected.

Checking the counters in perfmon I have a
\Processor(0)\% Processor Time
\Processor(1)\% Processor Time
but no (_total) which would probably explain it.

I have disabled all checks except uptime, nsc version and service state but still get the error.

It's not a major deal, I only have one server still on NT4 so I can live with it but I thought you should know.

From what I can tell this is some "strange error" in the Microsoft PDH subsystem. No one seems to know what it is or why it sometimes comes up.

In this case the error comes from the "CPU utilization collection" so it is not "check related" (as such). You could I guess try to see if "rebuilding counters" works, also you could, I guess, try to set the check time "lower" (there is an option under advanced for Check System to set the poll interval, just to see if that resolves it).

From what I understand this error "comes and goes" though.

If you can simulate this in some environment it would be interesting to debug it so I can see if I can resolve it.
