Vladimir Tretyakov commented on KAFKA-1481:
-------------------------------------------
Hi again,
65. Honestly I'd prefer allBrokers=true and allTopics=true or maybe
brokers=aggregated, topics=aggregated.
>From first view user will not know what this is about:
{code}
kafka.consumer:type=FetchRequestAndResponseMetrics,name=FetchRequestRateAndTimeMs,clientId=console-consumer-50964
{code}
and only after user will see something like:
{code}
kafka.consumer:type=FetchRequestAndResponseMetrics,name=FetchRequestRateAndTimeMs,clientId=console-consumer-50964,
broker=0
kafka.consumer:type=FetchRequestAndResponseMetrics,name=FetchRequestRateAndTimeMs,clientId=console-consumer-50964,
broker=1
{code}
user can understand (not sure) that like without 'broker=..' is aggregated
value, I'd prefer explicit definition.
[~jjkoshy] what do you think about:
"brokers=aggregated, topics=aggregated" ? In jconsole user will see
"aggregated" instead of "true", handy from my point of view.

> MBeans should not use dashes or underscores as separators because these
> characters are allowed in hostnames, topics, group and consumer IDs, etc.,
> and these are embedded in MBeans names making it impossible to parse out
> individual bits from MBeans.
> Perhaps a pipe character should be used to avoid the conflict.
> This looks like a major blocker because it means nobody can write Kafka 0.8.x
> monitoring tools unless they are doing it for themselves AND do not use
> dashes AND do not use underscores.
