SYMPTOMS

Consider the following scenario:
  • A Windows Driver Model (WDM) driver is used on a computer that is running Windows Server 2008 or Windows Vista. The driver provides a performance counter to report an elapsed time.
  • The driver calculates the elapsed time by querying the data that is returned from the WDM provider.
In this scenario, the counter returns invalid data when you use Performance Monitor to collect the data from this counter.

For example, the expected value is a number. However, the returned value is displayed as the "---" value.

CAUSE

The WDM provider provides incorrect data for both the Frequency_PerfTime field and the Timestamp_PerfTime field. This behavior causes the driver to calculate an invalid value for the elapsed time.
