Since the timestamps are different, I don't think it is one event being appended multiple times which is what I think Jacob suspects.

You'd want to add a filter to the appender, but there is not a built in filter that does what you want.

Not quite what you are looking for but search the archives for BurstFilter for an implementation of a filter that discard high volume

Thanks for reply :-)

The matter is addittivity IS set to false, there is a config:

log4j.appender.NETCOOL=org.apache.log4j.RollingFileAppender
log4j.appender.NETCOOL.threshold=DEBUG
log4j.appender.NETCOOL.layout=org.apache.log4j.PatternLayout
log4j.appender.NETCOOL.layout.ConversionPattern=%d{ABSOLUTE} %-5p [%c{1}] %m%n
log4j.appender.NETCOOL.append=true
log4j.appender.NETCOOL.file=${org.apache.geronimo.base.dir}/../log/ netcool.log
log4j.appender.NETCOOL.bufferedIO=false
log4j.appender.NETCOOL.maxBackupIndex=3
log4j.appender.NETCOOL.maxFileSize=10MB

# set the default priority to INFO for all micromuse/ibm loggers
log4j.category.com.ibm.tivoli=INFO,NETCOOL
log4j.category.com.micromuse=INFO,NETCOOL
# override any specific loggers
log4j.category.com.micromuse.common.util.Debug=DEBUG
log4j.additivity.com.ibm.tivoli=false
log4j.additivity.com.micromuse=false

And again, there is a lot of duplicates:

Sure, by setting additivity to false. Post your config. BTW, don't post it to the log4j-dev list. post it to the log4j-user list. The dev list isn't for
general user question, but for Log4j development issues.

Hi all,



Is it possible to filter messages going to logfile in 1.2 version? Problem:

05:00:36,004 DEBUG [Debug]

Is it possible to log only first such message and just count duplicates?



TIA.
