Connecting to multiple jmx instances using Splunk for JMX

sjanwity — Tue, 03 Feb 2015 14:13:00 GMT

We've installed Splunk 6 on our server which contains about 6 different JMX instances. We want to hook all of them up into our Splunk JMX plugin.

Is it as easy as editing the config.xml file and adding a new jmx server host? Currently this is:

<jmxserver host="[[system name]]" jvmDescription="common_raw" jmxport="53632">

Which works fine but we want to onboard other JMX instances as well. Is there a simpler method I've missed? Sorry for not trying it out beforehand - this is a production box so I don't want to muck things up for everybody!

Look in jmx_ta/bin/config/examples/config_cluster_example.xml for an example configuration.

Thanks for the quick reply! It looks like for a cluster of servers though...I just want the JMX instances inside the same box but outputting through different ports?

It is for a cluster of JVMs , local or remote or a mixture of both.Trust me , I wrote it 🙂

Hi Damien

Using your example cluster file .. still getting an error. Any suggestion?
validation failed: "cluster" must be terminated by the matching end-tag

Post the actual error.

Post the actual xml config you are using.

You have a dangling jmxserver closing tag.
