This is a Zabbix template + script useful to monitor Redis Server & Redis Sentinel instances:

1. Copy zabbix-redis.py to /usr/local/bin/.

2. Add the redis_server.discovery & redis_server.stats and / or redis_sentinel.discovery & redis_sentinel.stats user parameters to Zabbix:

   UserParameter=redis_server.discovery[*],/usr/local/bin/zabbix-redis.py -i '$1' -t server discover $2 2> /dev/null
   UserParameter=redis_server.stats[*],/usr/local/bin/zabbix-redis.py -i '$1' -t server stats 2> /dev/null
   UserParameter=redis_sentinel.discovery[*],/usr/local/bin/zabbix-redis.py -i '$1' -t sentinel discover $2 2> /dev/null
   UserParameter=redis_sentinel.stats[*],/usr/local/bin/zabbix-redis.py -i '$1' -t sentinel stats 2> /dev/null
   

3. Import the templates. You may download the appropriate versions from the releases page or generate them using the Jinja2 skeletons:

   $ pip install jinja2-cli
   $ PYTHONPATH=. jinja2 \
       -D version={6.0,6.2,6.4,7.0,7.2,7.4} \
       [-D name='Redis Server'] \
       [-D description=''] \
       [-D release='trunk'] \
       --extension=extensions.zabbix.ZabbixExtension --strict -o template.xml template-app-redis-server.j2
   $ PYTHONPATH=. jinja2 \
       -D version={6.0,6.2,6.4,7.0,7.2,7.4} \
       [-D name='Redis Sentinel'] \
       [-D description=''] \
       [-D release='trunk'] \
       --extension=extensions.zabbix.ZabbixExtension --strict -o template.xml template-app-redis-sentinel.j2
   

4. Link hosts to the templates. Beware depending on the used template you must set a value for the {$REDIS_SERVER.LOCATIONS} or {$REDIS_SENTINEL.LOCATIONS} macro (comma-delimited list of Redis instances; port, host:port and unix:///path/to/socket formats are allowed). Additional macros and contexts are available for further customizations.
