|
|||
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:
