The data that gets sent to the master is the total of the health impacts for the different categories on a specific day.
This measures the active time, which is a percentage of time where the system was healthy.
The average is over the last 30 days, but only includes the number of days that health records exist.
Systems are grouped by desktops and servers depending on the operating system that is installed.
For servers, the baseline is the total time the machine is on. Active time isn’t used.
