> WIth KAFKA-622, we measure ProducerRequestStats and
> FetchRequestAndResponseStats at the SyncProducer and SimpleConsumer level
> respectively. We could also aggregate them in the high level Producer and
> ZookeeperConsumerConnector level to provide an overall sense of
> request/response rate/size at the client level. Currently, I am not
> completely clear about the math that might be necessary for such aggregation
> or if metrics already provides an API for aggregating stats of the same type.
> We should also address the comments by Jun at KAFKA-622, I am copy pasting
> them here:
> 60. What happens if have 2 instances of Consumers with the same clientid in
> the same jvm? Does one of them fail because it fails to register metrics?
> Ditto for Producers.
> 61. ConsumerTopicStats: What if a topic is named AllTopics? We use to handle
> this by adding a - in topic specific stats.
> 62. ZookeeperConsumerConnector: Do we need to validate groupid?
> 63. ClientId: Does the clientid length need to be different from topic length?
> 64. AbstractFetcherThread: When building a fetch request, do we need to pass
> in brokerInfo as part of the client id? BrokerInfo contains the source broker
> info and the fetch requests are always made to the source broker.
