Calculation
Every day:
- Count the number of machines that hit a crash in AudioSrv or AudioDg
- Count the number of machines which attempted to use audio
Final Calculation
Percent of machines hitting a crash = (number of machines hitting a crash) / (number of machines which attempted to use audio)
The value of the measure at any time is the seven-day rolling average of this percentage.
