Description

The storm-kafka `KafkaSpout` emits a metric group called kafkaPartition

These metric names are prefixed with

Partition{host=some.broker.host.mycompany.com:9092,-topic=some/topic/name,-partition=40}

Which makes for ugly, difficult to discover metrics on systems like Graphite.

The metric prefix should match the metrics emitted by the kafkaOffset metric group that look like:

topicName/partition<partitionNum>_
