/**
* Wfsolr Plugin (https://github.com/lexsimon/contrib/master/plugins/solr/wfsolr_)
* "Wf" stands for "RBS Web Factory" (http://www.rbs.fr.fr/webfactory/)
* author : alexandre.simon@rbs.fr
* Derived from nicolas.moussikian@shopbot-inc.com's plugin (https://raw.github.com/munin-monitoring/contrib/master/plugins/solr/solr-stats)
* 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, allow_url_open directive on
*
* Once the plugin is available you can symlink 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]
*
* Alexandre SIMON additions :
* - solr-[name of the core]-alias
* - suggest implementation
* - support for solr_(host|port|webapp) environment variables
* - default core handling
* - error handling
* - TODO: use curl to make requests
