Each enabled logging request for a given logger will be forwarded to all the appenders in that logger as well as the appenders higher in the hierarchy. In other words, appenders are inherited additively from the logger hierarchy. For example, if a console appender is added to the root logger, then all enabled logging requests will at least print on the console. If in addition a file appender is added to a logger, say X, then enabled logging requests for X and X's children will print on a file and on the console.
For a more detailed explanation see http://logging.apache.org/log4net/release/manual/introduction.html#HC-71 89308 In your case you only need to specify the <appender-ref> in the <root> element.
