I used https://github.com/sematext/jmxc to get a "dump" of Consumer JMX.
It's a simple jar that you call with java -jar jmxc.jar PID > jmx.dump .

I just sent out a separate email about the project that I've been working
on, Burrow, to change the way we're monitoring consumer status.
Like Joel said, the mbeans can be a little tricky to work with. Internally
at LinkedIn, we've always depended more on using a tool like the Consumer
Offset Chec
Hi Otis,
Yes this is a limitation in the old consumer. i.e., a number of
per-topic/partition mbeans remain even on a rebalance. Those need to
be de-registered. So if you stop consuming from some partition after a
rebalance that lag mbean currently remain which is why it remains
flat. This is a kn

what code do you use to poll the jmx end-point?

Even if that were the ca
I believe the JMX metrics reflect the consumer PRIOR to committing offsets
to Kafka / Zookeeper. But when you query from the command line using the
kafka tools, you are just getting the committed offsets.

Hi,
Here's something potentially useful.
1) Before: https://apps.sematext.com/spm-reports/s/eQ9WhLegW9 - the "flat
Lag situation"
2) I restarted the consumer whose lag is shown in the above graph
3) After restart: https://apps.sematext.com/spm-reports/s/4YGkcUP9ms - NO
lag at all!?
So that 815
Hi Jason,

Got some new info below! Could be a Kafka metrics bug

No, we're looking at MBeans that lo
I assume you are looking at a 'MaxLag' metric, which reports the worst case
lag over a set of partitions. Are you consuming multiple partitions, and
maybe one of them is stuck?
