Guozhang Wang commented on KAFKA-5613:
--------------------------------------
That's a good question. I looked through
https://github.com/apache/kafka/pull/3547 and one caveat is that it reports all
metrics to the endpoint than allowing users to selectively pick which objects /
attributes to report. So just to clarify my stands a bit more here:
1. For the performance testing and benchmarking purposes where users would more
likely do manual work like starting processes, starting jmx tools, etc, I think
the HTTPMetricsReporter may not be able to completely replace JMXTool's
functionality. But maybe JMXTrans can completely replace JMXTools.
2. For non-performance testing system test itself, I agree that replacing
jmx.py with http.py would be a good idea.
> Deprecate JmxTool?
> ------------------
>
> Key: KAFKA-5613
> URL: https://issues.apache.org/jira/browse/KAFKA-5613
> Project: Kafka
> Issue Type: Bug
> Affects Versions: 0.11.0.0
> Reporter: Ewen Cheslack-Postava
> Priority: Major
>
> According to git-blame, JmxTool has been around since October 2011. We use it
> in system tests, but we are thinking it might be best to replace it:
> https://issues.apache.org/jira/browse/KAFKA-5612
> When making modifications for system tests, we've had to take into account
> compatibility because this tool is technically included in our distribution
> and, perhaps unintentionally, a public utility.
> We know that "real" tools for JMX, like jmxtrans, are more commonly used, but
> we don't know who might be using JmxTool simply because it ships with Kafka.
> That said, it also isn't documented in the Kafka documentation, so you
> probably have to dig around to find it.
> Hopefully we can deprecate this and eventually move it either to a jar that
> is only used for system tests, or even better just remove it entirely. To do
> any of this, we'd probably need to do at least a cursory survey of the
> community to get a feel for usage level.
