Yes, it's what I said: create new sift appender. Regards JB

You can do this by using MDC combined with filters (I implemented that in Pax logging a few years back). E g if you use this root logger: log4j.rootLogger=INFO, stdout, info, error, bundle, context, osgi:* And you define the "bundle" log as follows: log4j.appender.bundle=org.apache.log4j.sift.MDCSiftingAppender log4j.appender.bundle.key=bundle.name <http://bundle.name> log4j.appender.bundle.default=karaf log4j.appender.bundle.appender=org.apache.log4j.RollingFileAppender log4j.appender.bundle.appender.MaxFileSize=1MB log4j.appender.bundle.appender.MaxBackupIndex=2 log4j.appender.bundle.appender.layout=org.apache.log4j.PatternLayout log4j.appender.bundle.appender.layout.ConversionPattern=%d{ISO8601} | %-5.5p | %-16.16t | %-32.32c{1} | %-32.32C %4L | %m%n log4j.appender.bundle.appender.file=${logdir}/bundles/$\\{bundle.name <http://bundle.name>\\}.log log4j.appender.bundle.appender.append=true log4j.appender.bundle.threshold=INFO You will end up with a separate log file per bundle (named with the bundle's name). I use a custom variable (${logdir}) to specify where to create the log file but you can do as you wish. In this case these log files will be at INFO level. Sometimes I want TRACE logging on a specific bundle. I can then do as follows: log4j.rootLogger=TRACE, stdout, info, error, bundle, context, osgi:*, bundle_trace log4j.appender.bundle_trace=org.apache.log4j.sift.MDCSiftingAppender log4j.appender.bundle_trace.key=bundle.name <http://bundle.name> log4j.appender.bundle_trace.default=karaf log4j.appender.bundle_trace.appender=org.apache.log4j.RollingFileAppender log4j.appender.bundle_trace.appender.MaxFileSize=10MB log4j.appender.bundle_trace.appender.MaxBackupIndex=2 log4j.appender.bundle_trace.appender.layout=org.apache.log4j.PatternLayout log4j.appender.bundle_trace.appender.layout.ConversionPattern=%d{ISO8601} | %-5.5p | %-16.16t | %-32.32c{1} | %-32.32C %4L | %m%n log4j.appender.bundle_trace.appender.file=${logdir}/bundles/trace/$\\{bundle.name <http://bundle.name>\\}.log log4j.appender.bundle_trace.appender.append=true log4j.appender.bundle_trace.threshold=TRACE log4j.appender.bundle_trace.filter.a=org.apache.log4j.filter.MDCMatchFilter log4j.appender.bundle_trace.filter.a.exactMatch=false log4j.appender.bundle_trace.filter.a.keyToMatch=bundle.name <http://bundle.name> log4j.appender.bundle_trace.filter.a.valueToMatch=org.apache.aries.blueprint.core # DenyAllFilter should always be the last filter log4j.appender.bundle_trace.filter.z=org.apache.log4j.varia.DenyAllFilter In the above example I create a separate TRACE log for the bundle with the name "org.apache.aries.blueprint.core". It is also possible to configure custom logging for a particular camel context which we do in our integration platform based on Karaf and Camel. /Bengt 2016-06-30 13:59 GMT+02:00 Jean-Baptiste Onofré <j...@nanthrax.net <mailto:j...@nanthrax.net>>: Then it's different sift appenders that you have to define. Generally speaking, you don't need sift for what you want: if your bundles use different loggers, then, just create the logger category in the pax-logging config.
