Redis is an open source (BSD licensed), in-memory data structure store, used as a database, cache and message broker.

This integration will monitor your Redis cluster by collecting metrics from Redis INFO command.

Once enabled you will get a default Redis dashboard to help you get started monitoring your key Redis metrics.
