The defaut metricsets are `info` and `keyspace`.

=== Module-specific configuration notes

The Redis module has these additional config options:

*`password`*:: The password to authenticate, by default it's empty.
*`idle_timeout`*:: The duration to remain idle before closing connections. If
  the value is zero, then idle connections are not closed. The default value
  is 2 times the module period to allow a connection to be reused across
  fetches. The `idle_timeout` should be set to less than the server's connection
  timeout.
*`network`*:: The network type to be used for the Redis connection. The default value is
  `tcp`.
*`maxconn`*:: The maximum number of concurrent connections to Redis. The default value
  is 10.

=== Compatibility

The Redis metricsets were tested with Redis 3.2.12, 4.0.11 and 5.0-rc4,  and are expected
to work with all versions >= 3.0.
