JMX naming

Elastic Stack Elasticsearch
1

Hi Shay,

we're in the last stages of productionising our solution. We are now facing
a little issue with the monitoring of our app using JMX. Elasticsearch seems
to be adding a random (enough) node id to the name of the ES MBean which
changes. This means that we can't currently monitor ES.

Is there any way to override this behaviour such that the MBean is exposed
with a static (or config derived) name?

Thanks,

I changed it to org.elasticsearch static one. The idea was to have each node a JMX aggregator of other nodes, but gave up on that. Here is the issue: JMX: Don't use node id and name as part of the jmx registration, use static org.elasticsearch · Issue #843 · elastic/elasticsearch · GitHub.

As a side note, not a big fan of JMX, very heavy on system resources. The different stats/info/status APIs in elasticsearch gives you a lot of information.

Actually, those include, currently, much more info than JMX, so if you miss something, it can be easily added to JMX.

Cool, thanks!

Yeah I don't like JMX much either, but it's what our support teams use so if
I don't want to provide 24/7 support I have to expose things in JMX :frowning:

Cheers,

Paul.

Hi,

http://www.elasticsearch.org/guide/reference/modules/jmx.html says that :

jmx.domain

The domain under which the JMX will register under can be set using
jmx.domain setting. It defaults to {elasticsearch}.

Perhaps, you could try to set jmx.domain property ?

When I start a JMX connection, I get :

It seems to be correct

Hope this helps

Yes, but then you will still have the node id/name as a second level element, which is no longer the case.
