This is a Zabbix template + script useful to monitor Varnish High Availability (VHA) Agent instances:

  1. Copy zabbix-vha-agent.py to /usr/local/bin/.

  2. Add the vha_agent.discovery and vha_agent.stats user parameters to Zabbix:

    UserParameter=vha_agent.discovery[*],sudo /usr/local/bin/zabbix-vha-agent.py -i '$1' --default-vha-agent-status-file '/var/lib/vha-agent/vha-status' discover $2
    UserParameter=vha_agent.stats[*],sudo /usr/local/bin/zabbix-vha-agent.py -i '$1' --default-vha-agent-status-file '/var/lib/vha-agent/vha-status' stats
    

    You'll have to grant zabbix user sudo permissions to execute the /usr/local/bin/zabbix-vha-agent.py script. This is required to access contents of VHA Agent status files.

  3. Import the template. You may download the appropriate version from the releases page or generate it using the Jinja2 skeleton:

    $ pip install jinja2-cli
    $ jinja2 \
        -D version={4.0,4.2,4.4,5.0,5.2} \
        [-D name='VHA Agent'] \
        [-D description=''] \
        --strict -o template.xml template-app-vha-agent.j2
    
  4. Link hosts to the template. Beware you must set a value for the {$VHA_AGENT.LOCATIONS} macro (comma-delimited list of VHA Agent status files). Usually you should leave its value blank when running a single VHA Agent instance per server. Additional macros and contexts are available for further customizations.
