IRIS Health Monitor is part of System Monitor (see here).
The intention is to further process the captured sensor reading in order to identify the "health" of a system by checking the sensor reading values against pre-defined Base, Min and Max absolute values, and alert accordingly. Additionally, instead of absolute values, you can create Charts (which can be different for different periods of a day), that contain a learned minimum and maximum value after a time spent by the system (at least 24 hours) analysing sensor readings.
The sensor readings included in Health Monitor are defined here.
The question I am posing is, - Is it possible to create user-defined, sensors (in the same way as you can using Application Monitor), to be included within Health Monitor (which can be added to a Chart where there is no absolute Base, Min and Maximum values pre-defined) ?
