Re: How to filter on logger name.
The only bit i was missing was the threshold on the appenders.
log4j.rootLogger=ERROR, R
log4j.appender.R=org.apache.log4j.RollingFileAppender
log4j.appender.R.File=${catalina.home}/logs/root.log
log4j.appender.R.MaxFileSize=128MB
log4j.appender.R.MaxBackupIndex=5
log4j.appender.R.layout=org.apache.log4j.PatternLayout
log4j.appender.R.layout.ConversionPattern=%p %t %c - %m%n
log4j.appender.R.threshold=ERROR
log4j.logger.org.springframework=DEBUG, spring
log4j.logger.com.another.package=DEBUG, spring
log4j.appender.spring=org.apache.log4j.RollingFileAppender
log4j.appender.spring.File=${catalina.home}/logs/spring.log
log4j.appender.spring.MaxFileSize=128MB
log4j.appender.spring.MaxBackupIndex=5
log4j.appender.spring.layout=org.apache.log4j.PatternLayout
log4j.appender.spring.layout.ConversionPattern=%p %t %c - %m%n
log4j.appender.spring.threshold=ERROR

It is by far more common and efficient to use thresholds than filters
for the scenario you described. Thresholds are used to discard
logging requests prior to the creation of a LoggingEvent, filters are
only applied after the LoggingEvent is created.
You could set the threshold on the root logger to something high
(ERROR, FATAL or OFF) and the threshold to logger corresponding to
your package or class of interest to something lower like DEBUG or
INFO. All of that should be covered http://logging.apache.org/log4j/
docs/manual.html.
If you really did need to use a filter, there are two different
classes (ExpressionFilter and LoggerMatchFilter) in the log4j extras
companion (not yet released, but release candidates are available)
that can filter on logger name.

How to filter on logger name.

Re: How to filter on logger name.
Hi,
I have setup the same kind of thing at work but don't have access to
the files at the moment.
From memory the following will log all error and above messages to
root.log. And all messages from the org.springframework and
com.another.package packages go to spring.log.
log4j.rootLogger=ERROR, R
log4j.appender.R=org.apache.log4j.RollingFileAppender
log4j.appender.R.File=${catalina.home}/logs/root.log
log4j.appender.R.MaxFileSize=128MB
log4j.appender.R.MaxBackupIndex=5
log4j.appender.R.layout=org.apache.log4j.PatternLayout
log4j.appender.R.layout.ConversionPattern=%p %t %c - %m%n
log4j.logger.org.springframework=DEBUG, spring
log4j.logger.com.another.package=DEBUG, spring
log4j.appender.spring=org.apache.log4j.RollingFileAppender
log4j.appender.spring.File=${catalina.home}/logs/spring.log
log4j.appender.spring.MaxFileSize=128MB
log4j.appender.spring.MaxBackupIndex=5
log4j.appender.spring.layout=org.apache.log4j.PatternLayout
log4j.appender.spring.layout.ConversionPattern=%p %t %c - %m%n
So you just setup a logger and appender for each class/package that
you want to separate out.
If someone else hasn't enlightened you I'll send you some config tomorrow.

Ben

Re: How to filter on logger name.
Sending logs from only certain loggers to an appender is one of the most common ways to use log4j.
