I've gone through the below link to refer the error details
Monitor name :Host Monitor. Cannot access data for measurement PhysicalDisk|% Disk Time|_Total on machine on XYZ. Details: A counter with a negative value was detected. Hint: Check that there is such a measurement on the machine (use the Add Machine dialog box) (entry point: CNtMeasurement::GetNewData3). [MsgId: MMSG-47295]
HP has given the Fix as below:
Both the error messages do not affect any load tests and do not interfere with any other Performance Center functionality. Although they cannot be suppressed they are harmless and may be ignored.
Any one is able to see the above error message in PC 11.0 during the test execution? Please post your updates.
I still see these errors in LR 11.51 and PC as well. Though KB article in resolution is 4 years old and issue still persists.
Monitor name :Windows Resources. Cannot access data for measurement PhysicalDisk|% Idle Time|_Total on machine << MachineName >>.
Details: A counter with a negative value was detected.
Resolution to ignore errors doesn't make sense as these monitors are monitored for reasons and critical when we see abnormality in results. LoadRunner or PC shouldn't throw such false positive errors which afftect analysis and reporting of performance tests.
As technology moves ahead bar gets higher and higer and demands high precision so suggestions\ recommendations to ignor looks unreasonalble.
