Measure IDs 29745823

Calculation

Every day:

  1. Measure is accounting for failures at an endpoint level, that is, if there is a failure on a specific endpoint that the driver is targeting, it is counted as a failure.
  2. Count the number of machine endpoints that hit a hang in AudioSrv or AudioDg
  3. Count the number of machine endpoints which attempted to use audio

Final Calculation

Percent of machine endpoints targeted by a driver hitting a hang = (number of machine endpoints targeted by a driver hitting a hang) / (number of machine endpoints targeted by a driver which attempted to use audio)

The value of the measure at any time is the seven-day rolling average of this percentage.
