zabbix-sensors

Zabbix template & scripts to discover & monitor Linux sensors

Features:

• Low-level discovery of sensors: temperature (with thresholds), fans and power
• Triggers on temperature & fans (detect stopped fan, adjustable)

Usage:

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

Requirements:

• lm-sensors installed

Macros to control behavior:

• {$SENSORS_CRIT}: override discovered crit thresholds
• {$SENSORS_HIGH}: override discovered max thresholds
• {$SENSORS_FAN_STOP_TRIG}: set to 1 to enable fan stop trigger

Notes:

• All the needed data can be obtained directly from SysFS, but sensors binary does a lot of work under the hoods to obtain the bus type etc, so it's not easy to get device names like coretemp-isa-0000 from SysFS manually and they're required by Zabbix's sensor function.
• The actual arguments to the discovery script are not used, but are there rather to fullfill Zabbix's unique key constraints.
• Power sensors are not working now in Zabbix (tested in 4.0.3) for some reason (or I'm doing something wrong).
