Kyle Banker commented on KAFKA-1902:
------------------------------------
Couple ideas here:
1. [~junrao] For what its worth, the typical way of representing types in
Graphite is with an extra level of hierarchy: i.e., instead of
BrokerTopicMetrics.topic=foo, we'd do BrokerTopicMetrics.Topics.foo.
2. The character used to replace the dots in topic names could be configurable.
3. The default replacement could indeed be underscores. This is, I believe, the
standard conventions used when a hostname is part of a Graphite metric: simply
replace dots with underscores. (Note that although host names aren't allowed to
have underscores in the real world, DNS names often do. Still, no confusion
results).
> fix MetricName so that Yammer reporter can work correctly

> Currently, we create MetricName in the following format.
> group: "kafka.server"
> type: "BrokerTopicMetrics"
> name: "BytesInPerSec"
> scope: null
> mBeanName:
> "kafka.server:type=BrokerTopicMetrics,name=BytesInPerSec,topic=test"
> However, Yammer metric reporter seems to only use the first four fields
> group, type, name and scope during reporting.
