The Connection to Redis frame displays the net.connectedClients value from the New Relic Redis sample data. It displays the connections count by New Relic application (environment) and node.
The Commands per second by node frame shows the Redis commands by node per second over the selected timeframe.
The Redis % of memory used frame shows the % of max memory used by the Redis servers.
