SysTrack calculates system health by measuring productivity impact, active time, and quality time to generate a percentage‑based health score.

One of the fundamentals of SysTrack is the unique concept of system health. With SysTrack, system health is determined by measuring key performance impacts that relate specifically to productivity. Productivity impact, which is visible in SysTrack visualizers, is calculated in the Health observation to determine the amount of time per week that a system is being constrained by various issues that can affect user productivity.
Active time shows how many hours during the week a system was actively used, as opposed to sitting in screensaver mode or display lock.
The health score is also referred to as system quality time, and both are reported as a percentage, with 100% being perfect. The health score is determined by the following formula:
System quality time (%) = (Active time without productivity impact ÷ Active time) × 100
In simple terms, health—or quality time percentage—is the amount of active time without productivity impact divided by the total amount of active time, multiplied by 100.
Looking at this demo environment, here’s an example:
The system in question has been active for an average of 162.3 hours per week.
8.8 of those hours have been impacted by issues such as CPU throttling, slow connections, and so forth.
Subtracting the impact hours from active time gives the active time without productivity impact:
162.3 − 8.8 = 153.5 hours of active time without productivity impact.
Then:
153.5 hours without impact ÷ 162.3 total active hours × 100 =
a health score, or quality time percentage, of 94.6%.
