This script is run from scheduler periodically, sending notification on
health related events:
* high CPU load
* voltage jumps up or down more than configured threshold or drops below limit
* power supply failed or recovered
* temperature is above or below threshold
Note that bad initial state will not trigger an event.
Only sensors available in hardware can be checked. See what your
hardware supports:
Monitoring CPU load works on all devices. Other than that only sensors
available in hardware can be checked. See what your hardware supports:
