Log filters
Log filters help control more detailed logging settings that are not handled by usual log level settings.
A filter provides an optional, secondary control over what is logged, beyond the control provided by setting the level. Applications can apply a filter mechanism to control logging output through the logging APIs. An example of filter usage is to suppress all the events with a particular message key.
A filter is attached to a logger or log handler using the appropriate setFilter method. For a complete list of filter methods, see the java.util.logging documentation at http://java.sun.com/javase/
