By default the Category is the fully qualified class name of the method being monitored. This is then added to the BaseCategory Property along with "Feature Usage" to form the full category name.
By setting the Category property explicitly you can put a specific field into a subcategory underneath "Feature Usage".
Two features with the same Category and Name must have a common set of parameters or the event metrics necessary for analysis will not record correctly. If you need to associate the same feature Category and Name with methods that have different signatures disable parameter recording by setting the LogParameters Property to false.
