Notify about health state

⬅️ Go back to main README

ℹ️ Info: This script can not be used on its own but requires the base installation. See main README for details.

Description

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.

Monitoring CPU load works on all devices. Other than that only sensors available in hardware can be checked. See what your hardware supports:

/system/health/print;

Sample notifications

CPU load

Voltage

Temperature

PSU state

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 and/or telegram.
