Jun Rao commented on KAFKA-1481: -------------------------------- I am wondering if you can get around the problem by just parsing the mbean names a bit differently. For example, for an mbean like the following in which "topic-1" is the topic name. When parsing the name part, you can find the last "-" to break the name into two parts. "kafka.server":type="BrokerTopicMetrics",name="topic-1-BytesInPerSec" > Stop using dashes AND underscores as separators in MBean names > -------------------------------------------------------------- > > Key: KAFKA-1481 > URL: https://issues.apache.org/jira/browse/KAFKA-1481 > Project: Kafka > Issue Type: Bug > Components: core > Affects Versions: 0.8.1.1 > Reporter: Otis Gospodnetic > 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. > See: http://search-hadoop.com/m/4TaT4lonIW -- This message was sent by Atlassian JIRA (v6.2#6252)
