Description of jmx exposed metrics?
Hi!
Sorry if this question has already been answered, but I've search the
archives, the project page and the wiki unsuccessfully.
I'd like to know the meaning of the jmx exposed metrics. I can guess based
on the name but I'd like to be sure. Plus, some of them seem to be reset
when I restart the server (or when a new file is created in the topic
directory, I'm not sure), and some of them don't.
Is there a doc anywhere with this info?
PD: I'm using 0.7.2 and I know 0.8 changes some things, but I guess the
basic stuff will remain the same...

Yes, I meant messages stored in the broker. We have the feeling that some
messages are being lost in the mirrormaker process, and I'd like to make
sure that's not happening. As the deployment is really young, we still
haven't deleted any messages, so the number of messages in FE and BE should
be the same, that's why I was thinking about that metric. But if we don't
have it, I'm looking for new approaches...

Re: Description of jmx exposed metrics?
Posted by Jun Rao <ju...@gmail.com>.
Do you mean the # messages stored in the broker (since old messages are
deleted automatically)? We don't have that jmx right now, but it's probably
useful to add one. We do have a jmx on # unconsumed messages for a given
consumer.
Thanks,

Re: Description of jmx exposed metrics?

Or even simpler: Is there any way to know the number of messages in a
topic, in a server? Is that "kafka.logs.topic -> CurrentOffset"? If not,
what does that "CurrentOffset" means?

Re: Description of jmx exposed metrics?
Posted by Tomas Nunez <nu...@pythian.com>.
Yes, but this counts how many messages went in that topic, right? This
should always be increasing and never decreasing, if I understand correctly.
I'm asking that because in my kafka configuration I have 18 topics, and in
all of them but one this metric is increasing. There is a topic where this
metric is going up and down like crazy, and I'm worried that something may
be wrong with it.
And strangely this happens in 4 of 5 servers. There is a server where this
topic is only increasing, never decreasing...

Yes. All jmx beans start from 0 on broker startup.

Re: Description of jmx exposed metrics?
Posted by Tomas Nunez <nu...@pythian.com>.
Then I guess mi next question is:
The jmx metric "Kafka -> kafka.BrokerTopicStat.<topic_name> -> MessagesIn"
counts how many messages went in that topic since kafka was started, and it
will reset to 0 when I restart the service, right?
Same thing for Kafka -> kafka.BrokerAllTopicStat -> MessagesIn, right?
Thanks!

Yup... I read both of them, but I saw much more data in the jmx and I was
trying to understant it to make the most of them :)
But I'll settle knowing that is the useful data. Thank you both!
