The INFO command returns information and statistics about the server in a format that is simple to parse by computers and easy to read by humans.
See https://redis.io/commands/info for full information.INFO or info displays all sections, if you need just a specific section, run "info <section name>" e.g: info cluster will just display the cluster information.
