A broker may be alive but unable to establish new connections, emit metrics, or emit logs due to failed DNS resolution. It would be helpful to have a metric that counts the number of brokers registered to a cluster since it is not altogether obvious that a particular broker is not emitting metrics or logs. It would also be helpful to count the number of unfenced brokers so that it is known how many brokers are present in the metadata response and how many are not.
