Notify about health state
=========================
[◀ Go back to main README](../README.md)
> **Info**: This script can not be used on its own but requires the base
> installation. See [main README](../README.md) for details.
Description
-----------
This script is run from scheduler periodically, sending notification on
health related events:
* 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:
/system/health/print;
### Sample notifications
#### Voltage

#### Temperature

![check-health notification](check-health.d/notification-03-temperature-ok.svg)
#### PSU state
![check-health notification](check-health.d/notification-04-psu-fail.svg)
![check-health notification](check-health.d/notification-05-psu-ok.svg)
Requirements and installation
-----------------------------
Just install the script and create a scheduler:
$ScriptInstallUpdate check-health;
/system/scheduler/add interval=1m name=check-health on-event="/system/script/run check-health;" start-time=startup;
Configuration
-------------
The configuration goes to `global-config-overlay`, these are the parameters:
* `CheckHealthTemperature`: an array specifying temperature thresholds for sensors
* `CheckHealthVoltageLow`: value (in volt*10) giving a hard lower limit
* `CheckHealthVoltagePercent`: percentage value to trigger voltage jumps
Also notification settings are required for e-mail,
[matrix](mod/notification-matrix.md) and/or
[telegram](mod/notification-telegram.md).
