The load is defined as something different... https://en.wikipedia.org/wiki/Load_(computing) So let's update the wording and use 'utilization' instead. ---- ✂️ ---- 🧮️📈️ Health warning: CPU utilization The average CPU utilization on MikroTik is at 76%! ---- ✂️ ---- 🧮️📉️ Health recovery: CPU utilization The average CPU utilization on MikroTik decreased to 64%. ---- ✂️ ----

Notify about health state
|
||
=========================
|
||
|
||
[⬅️ Go back to main README](../README.md)
|
||
|
||
> ℹ️ **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:
|
||
|
||
* high CPU utilization
|
||
* low available free RAM
|
||
* voltage jumps up or down more than configured threshold
|
||
* voltage drops below hard lower limit
|
||
* power supply failed or recovered
|
||
* temperature is above or below threshold
|
||
|
||
Note that bad initial state will not trigger an event.
|
||
|
||
Monitoring CPU utilization and available free RAM 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 utilization
|
||
|
||
|
||
|
||
|
||
#### Available free RAM
|
||
|
||
|
||
|
||
|
||
#### 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](mod/notification-email.md),
|
||
[matrix](mod/notification-matrix.md) and/or
|
||
[telegram](mod/notification-telegram.md).
