/**
* SolR Plugin
* author : nicolas.moussikian@shopbot-inc.com
*
* This plugin allows to graph any data present in the stats report on a multi core SolR instance
* AKA : http://127.0.0.1:8080/solr/[name of the core]/admin/stats.jsp
* Verify the server where the munin-node instance is can access that URL
*
* You need to have a PHP 5.2.6+ CLI installed too
*
* Once the plugin is available you can simlink it with the following naming convention :
* solr-[name of the core]-[name of the stats section - ex.: CORE]-[name of the entry in the xml - ex.: searcher]-[name of the stat to graph - ex.: numDocs]
