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

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

2. Add the redis_server.discovery and / or redis_sentinel.discovery 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_sentinel.discovery[*],/usr/local/bin/zabbix-redis.py -i '$1' -t sentinel discover $2 2> /dev/null
   

3. Add required jobs to the zabbix user crontab (beware of the -i, -t and -s options). This will submit Redis Server and / or Redis Sentinel metrics through Zabbix Sender:

   * * * * * /usr/local/bin/zabbix-redis.py -i '6379, 6380, 6381, 7000, 7001, 7002, 7003, 7004, 7005' -t server send -c /etc/zabbix/zabbix_agentd.conf -s dev > /dev/null 2>&1
   * * * * * /usr/local/bin/zabbix-redis.py -i '26379, 26380, 26381' -t sentinel send -c /etc/zabbix/zabbix_agentd.conf -s dev > /dev/null 2>&1
   

4. Import the required templates (template-app-redis-server.xml and / or template-app-redis-sentinel.xml files).

5. Add an existing / new host to the Redis servers group and link it to the right template (Template App Redis Server for Redis Server and Template App Redis Sentinel for Redis Sentinel). 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).
