Adding Categories Granularly

You can also add categories with very granular information using the category() method. This method will allow you to add a category definition with a range of severity levels and even a list of which appenders to respond to.
public void category(
    string name,
    [numeric levelMin='0',]
    [numeric levelMax='4',]
    [string appenders='*']
)
Parameters:
Name
Description
name
A unique name for the category to register. Only unique names can be registered per instance.
levelMin
The default min log level for this category. (OPTIONAL. Defaults to 0 [FATAL].)
levelMax
The max default log level for this category. (OPTIONAL. Defaults to 4 [DEBUG].)
appenders
A list of appender names to configure this category with else it will use all the appenders in the root logger. You can also use * to add all registered apenders. (OPTIONAL)
Example
//log all email service messages to the MyLogFileAppender and the Console.
config.category( name="org.model.EmailService", appenders="MyLogFileAppender,Console" );
