	You can set a threshold on each appender, which means that the
appender 
	will discard all messages lower than the threshold. So if it is
acceptable to
	send *debug and above* to console, *info and above* to file and
*error and above*
	to NTEventLog, then this is easy. To set a threshold in an xml
config file, try:
	<param name="Threshold" value="INFO" /> within the Appender
definition.

	If you really want exactly what you described above, then you can
use the
	PriorityRangeFilter filter class that I posted a while ago (search
the email
	archives). It hasn't (yet?) been put into log4j cvs.

	Cheers,

	Simon
