             Summary: Use metrics CSV reporter instead of jmx tool for system 
tests
                 Key: KAFKA-541
                 URL: https://issues.apache.org/jira/browse/KAFKA-541
             Project: Kafka
          Issue Type: Bug
    Affects Versions: 0.8
            Reporter: Joel Koshy


The existing system test framework spawns off a bunch of jmxtool processes to 
collect metrics. This is rather heavy-weight and also, requires advance 
knowledge of all the beans (many of which are dynamically registered). E.g., 
per-topic stats pop-up only after the topics are produced to.

Since we are using metrics-core, we can just turn on the CSV reporter to 
collect these stats. I had originally thought version 2.1.3 had various bugs 
that rendered it unusable for CSV reporter, but I gave it another try and it 
seems to be fine. Will post some output.
