Zabbix template & script to monitor UPS exposed through NUT (https://networkupstools.org).

Currently only basic parameters are gathered (which are available on my UPS). Feel free to do PR to add other stuff, preferably in form of low-level discovery so that if it's not available - items are not created.

Single Python script that emits all information needed for discovery & data gathering in a single JSON. All items are defined as Dependent and extract relevant data using JSONPath queries.

• Low level discovery of UPS
• Items:
  • Voltage & Frequency
  • Battery voltage & charge
  • UPS Status
• Triggers:
  • Voltage out of bounds
  • UPS status is not healthy
  • UPS is calibrating/in bypass/charging
• Optional authentication (fill {$NUT_USERNAME} and {$NUT_PASSWORD} macros to enable)
• Zabbix agent passive checks. Can be converted to active if needed.
• Macros to customize triggers

• Tested on Zabbix 5.2, but should work on 4.2+
• Python3

• Place nut.conf in /etc/zabbix/zabbix_agentd.d
• Place nut.py in /etc/zabbix/scripts You can put it into any other place, but then you'll have to adjust nut.conf
• Restart zabbix-agentd
• Import template_nut.xml
• You're good to go
