Hi [~jjkoshy] thx for your feedback, will change, one question from me:
What if I include Kafka version in any of the MBeans? It will easy for
external tools to detect Kafka version and use parsing rules for particular
version. Something like Elasticsearch provides by http (Kafka will provide by
JMX).
{code}
curl localhost:9200
{
...
"version" : {
"number" : "1.3.2",
"build_hash" : "dee175dbe2f254f3f26992f5d7591939aaefd12f",
"build_timestamp" : "2014-08-13T14:29:30Z"
....
}
}
{code}
Maybe you can point out code place where I can get current Kafka version?

> 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.
