> 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.
