-------------------------------------------
Hi, Jun,
Thx that you found a time to look at patch, I've added another regarding your
suggestion, now in JMX you will see (hope it is what you need):
{code}
"kafka.server":type="FetcherStats",name="RequestsPerSec",clientId="af_servers",threadName="ConsumerFetcherThread",groupId="af_servers",consumerHostName="wawanawna",timestamp="1413306414731",uuid="4624cb0f",fetcherId="0",sourceBrokerId="0",brokerHost="wawanawna",brokerPort="9092"
"kafka.server":type="FetcherLagMetrics",name="ConsumerLag",clientId="af_servers",threadName="ConsumerFetcherThread",groupId="af_servers",consumerHostName="wawanawna",timestamp="1413306414731",uuid="4624cb0f",fetcherId="0",sourceBrokerId="0",brokerHost="wawanawna",brokerPort="9092",topic="spm_topic",partitionId="0"
"kafka.consumer":type="ZookeeperConsumerConnector",name="OwnedPartitionsCount",clientId="af_servers",groupId="af_servers",topic="spm_topic"
"kafka.consumer":type="FetchRequestAndResponseMetrics",name="FetchResponseSize",clientId="af_servers",threadName="ConsumerFetcherThread",groupId="af_servers",consumerHostName="wawanawna",timestamp="1413306414731",uuid="4624cb0f",fetcherId="0",sourceBrokerId="0",allBrokers="true"
{code}

Also, your patch doesn't seem to apply to latest trunk.
git apply ~/Downloads/KAFKA-1481_2014-10-13_18-23-35.patch
error: core/src/main/scala/kafka/common/ClientIdTopic.scala: No such file or
directory

Interesting...
1. I've worked with 0.8.2 branch, not trunk
2. ClientIdTopic.scala - I've added this file (must be in patch).
Added 2 equal patches (created them in different way):
1. 'git diff'
2. With help from IDEA IDE.
Try please, maybe one of them will work
Thx again.

> Project: Kafka
> Issue Type: Bug
> Components: core
> Affects Versions: 0.8.1.1
> Reporter: Otis Gospodnetic
> Priority: Critical
> Labels: patch
> Fix For: 0.8.2

> Attachments: KAFKA-1481_2014-06-06_13-06-35.patch,

>
> 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.
