A feature was added in SOLR-1843 specificly to help address this potential
collision, by allowing you to override the rootName used in your jmx /
declaration (by default it's solr/${corename}) but looking at the issue
now i see it was only committed to trunk...
https://issues.apache.org/jira/browse/SOLR-1843
...even though this looks like a fairly straight forward candidate to
merge back to 3x. i'll look into it.

Re: a question on jmx solr exposure
Well, we don't use multicore feature of SOLR, so in our case SOLR instances are just separate web-apps. The web-app loading order probably then affects on which app gets hold of a jmx 'pipe'. We should probably start using the feature to collect stats from different cores at the same time. Thanks.

Re: a question on jmx solr exposure
That's absolutely right. Thanks for the suggestion.

But, as I pointed out earlier, you should still have a different solrconfig.xml file for each web app, and thus should be able to set up JMX differently for each. Regards, Gora -- Regards, Dmitry Kan

Re: a question on jmx solr exposure
Solved by exposing jmx only on one of the cores, as it is of a more interest than the other one.
