> Today some topic/broker level metrics are only added the first time such an
> event (record-retry, record-error, etc) happens. This has a potential issue
> for customized mbean reporter which needs to register all the sensors at the
> time the new broker/topic is discovered. It is better to add such metrics at
> the very beginning when new topic/brokers are discovered.
