Zabbix template & scripts to discover & monitor Linux sensors

Features

  • Low-level discovery of sensors: temperature (with thresholds), fans, voltage and power
  • Triggers on temperature, fans and voltage (detect stopped fan, adjustable)
  • Data is gathered once as a single JSON and all other items are Dependent - extracted from raw JSON
  • All data is gathered directly from SysFS - no lm-sensors needed to function

Usage

  • Put sensors.conf in /etc/zabbix/zabbix_agentd.d folder
  • Put sensors.py in /etc/zabbix/scripts folder (or in any other, but then you'll need to adjust sensors.conf)
  • Import & link template

Requirements

  • Python3

Macros

  • {$SENSORS_FAN_LOW}: Low fan speed sensor threshold
  • {$SENSORS_TEMP_CRIT}: Crit value for temp sensors
  • {$SENSORS_TEMP_HIGH}: High value for temp sensors
  • {$SENSORS_TEMP_HYST}: Hysteresis for temp sensors to make sure that trigger is not firing when value oscillates over threshold and back
  • {$SENSORS_VOLTAGE_HIGH}: Voltage high threshold
  • {$SENSORS_VOLTAGE_LOW}: Voltage low threshold

Update 2023-06

  • Script was rewritten to gather data directly from sysfs instead of using sensors binary
  • Updated templates for 6.0 and 6.4

Update 2020-12

  • Script was rewritten from scratch to make use of new sensors argument -j to export in JSON format. If it's not supported then it'll fall back to parse raw text output of -u - this will stick for some time for backwards compatibility
  • Move to Python3
