Chris Burroughs commented on KAFKA-203: --------------------------------------- I *think* metrics is source compatible with 2.8, but I would need to investigate more. > Improve Kafka internal metrics > ------------------------------ > > Key: KAFKA-203 > URL: https://issues.apache.org/jira/browse/KAFKA-203 > Project: Kafka > Issue Type: New Feature > Components: core > Reporter: Jay Kreps > Assignee: Jay Kreps > > Currently metrics in kafka are using old-school JMX directly. This makes > adding metrics a pain. It would be good to do one of the following: > 1. Convert to Coda Hale's metrics package > (https://github.com/codahale/metrics) > 2. Write a simple metrics package > The new metrics package should make metrics easier to add and work with and > package up the common logic of keeping windowed gauges, histograms, counters, > etc. JMX should be just one output of this. > The advantage of the Coda Hale package is that it exists so we don't need to > write it. The downsides are (1) introduces another client dependency which > causes conflicts, and (2) seems a bit heavy on design. The good news is that > the metrics-core package doesn't seem to bring in a lot of dependencies which > is nice, though the scala wrapper seems to want scala 2.9. I am also a little > skeptical of the approach for histograms--it does sampling instead of > bucketing though that may be okay. -- This message is automatically generated by JIRA.
