The Logging Portlet allows a CMS Administrator in dotCMS to dynamically set logging levels of classes and packages at runtime that are known to the dotCMS JVM. It is also possible to add dynamic classes/packages to this plugin by, after making sure you are exporting them from your other dynamic plugins, add them to the Activator's start function (see example already there).
