Description

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.
