I want to build a High availability ELK monitoring system with redis.But a little confuse for how to make redis HA.
Redis Sentinel provides high availability for Redis. But i donot find any configuration for this on the document. https://www.elastic.co/guide/en/logstash/current/plugins-inputs-redis.html So can i use it for logstash as input and output? Anyone has experience for this?

Logstash Input Redis Plugin supports only one host in a host option.

I think you have 2 ways to get HA:

1) Continue use Redis. You can create dns A record (or edit your host file), that will point to multiple Redis servers, then put the record to host option.

2) Moving from Redis to Kafka:
