* 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
|

* Alexandre SIMON additions:
|

* - wfsolr-<coreName>-alias ; use suggest to get the list of available aliases
|

* - TODO: use curl to make requests
|
