Description
-----------
This script is run from scheduler periodically, sending notification on
health related events:
2023-02-14 19:09:41 +00:00
* high CPU utilization
2023-10-24 14:26:14 +00:00
* high RAM utilization (low available RAM)
2023-02-13 10:15:06 +00:00
* voltage jumps up or down more than configured threshold
* voltage drops below hard lower limit
2020-03-27 20:41:40 +00:00
* power supply failed or recovered
* temperature is above or below threshold
Note that bad initial state will not trigger an event.
2023-10-24 14:26:14 +00:00
Monitoring CPU and RAM utilization (available processing and memory
resources) works on all devices. Other than that only sensors available
in hardware can be checked. See what your hardware supports:

Requirements and installation
-----------------------------
Just install the script and create a scheduler:
$ScriptInstallUpdate check-health;
2023-03-31 15:45:55 +00:00
/system/scheduler/add interval=53s name=check-health on-event="/system/script/run check-health;" start-time=startup;
> ℹ ️
> precision of cpu utilization, escpecially on devices with limited
> resources. Thus an unusual interval is used here.
2020-03-27 20:41:40 +00:00
Configuration
-------------
2021-06-18 08:24:33 +00:00
The configuration goes to `global-config-overlay` , these are the parameters:
2020-03-27 20:41:40 +00:00
* `CheckHealthTemperature` : an array specifying temperature thresholds for sensors
2021-11-13 20:29:33 +00:00
* `CheckHealthVoltageLow` : value (in volt*10) giving a hard lower limit
2020-03-27 20:41:40 +00:00
* `CheckHealthVoltagePercent` : percentage value to trigger voltage jumps
2023-06-07 12:12:01 +00:00
> ℹ ️
> [`global-config`](../global-config.rsc) (the one without `-overlay`) to
> your local `global-config-overlay` and modify it to your specific needs.
2022-09-23 13:07:30 +00:00
Also notification settings are required for
[e-mail ](mod/notification-email.md ),
2023-10-11 05:40:55 +00:00
[matrix ](mod/notification-matrix.md ),
[ntfy ](mod/notification-ntfy.md ) and/or
2021-11-16 15:03:43 +00:00
[telegram ](mod/notification-telegram.md ).
