I have a system that uses both Apache Camel and Karaf.
I need some specific processor to log into a new log instead of the default one ,karaf.log.
I have reached that there is a file called "org.ops4j.pax.logging.cfg" that is responsible for logging configuration .
Here it's the file before I mess with it :

# Root logger
log4j.rootLogger=INFO, out, osgi:VmLogAppender
log4j.throwableRenderer=org.apache.log4j.OsgiThrowableRenderer
# CONSOLE appender not used by default
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d{ABSOLUTE} | %-5.5p | %-16.16t | %-32.32c{1} | %-32.32C %4L | %X{bundle.id} - %X{bundle.name} - %X{bundle.version} | %m%n
# File appender
log4j.appender.out=org.apache.log4j.RollingFileAppender
log4j.appender.out.layout=org.apache.log4j.PatternLayout
log4j.appender.out.layout.ConversionPattern=%d{ABSOLUTE} | %-5.5p | %-16.16t | %-32.32c{1} | %-32.32C %4L | %X{bundle.id} - %X{bundle.name} - %X{bundle.version} | %m%n
log4j.appender.out.file=${karaf.data}/log/karaf.log
log4j.appender.out.append=true
log4j.appender.out.maxFileSize=1MB
log4j.appender.out.maxBackupIndex=10
# Sift appender
log4j.appender.sift=org.apache.log4j.sift.MDCSiftingAppender
log4j.appender.sift.key=bundle.name
log4j.appender.sift.default=karaf
log4j.appender.sift.appender=org.apache.log4j.FileAppender
log4j.appender.sift.appender.layout=org.apache.log4j.PatternLayout
log4j.appender.sift.appender.layout.ConversionPattern=%d{ABSOLUTE} | %-5.5p | %-16.16t | %-32.32c{1} | %-32.32C %4L | %m%n
log4j.appender.sift.appender.file=${karaf.data}/log/$\\{bundle.name\\}.log
log4j.appender.sift.appender.append=true
Now I have added an extra File appender :
# Additional File appender
log4j.rootLogger=INFO, out, osgi:VmLogAppender # I removed the first log4j.rootLogger
log4j.appender.new=org.apache.log4j.RollingFileAppender
log4j.appender.new.layout=org.apache.log4j.PatternLayout
log4j.appender.new.layout.ConversionPattern=%d{ABSOLUTE} | %-5.5p | %-16.16t | %-32.32c{1} | %-32.32C %4L | %X{bundle.id} - %X{bundle.name} - %X{bundle.version} | %m%n
log4j.appender.new.file=${karaf.data}/log/new.log
log4j.appender.new.append=true
log4j.appender.new.maxFileSize=1MB
log4j.appender.new.maxBackupIndex=10
And from Camel , I logged from DSL :
process(exceptionProcessor).
process(doSmth).log(LoggingLevel.INFO,"new","That is a new file to log into")
The result now that it logs erverything on BOTH "new.log" & "karaf.log" file .
The question is : how could I log into"new.log" just in case a specific processor . Others will be logged into the karaf.log !!
