Anton Johansson updated LOG4J2-2021:
------------------------------------
Affects Version/s: 2.6
Description:
We're currently in the process of upgrading some of our components, including
upgrading from Log4J to Log4J2.
We previously had this configuration for splitting different logs to different
files:
log4j.appender.File=org.apache.log4j.sift.MDCSiftingAppender
log4j.appender.File.key=instanceId
log4j.appender.File.default=Unspecified
log4j.appender.File.appender=org.apache.log4j.sift.MDCSiftingAppender
log4j.appender.File.appender.key=bundleName
log4j.appender.File.appender.default=unspecified
log4j.appender.File.appender.appender=org.apache.log4j.RollingFileAppender
log4j.appender.File.appender.appender.layout=org.apache.log4j.PatternLayout
log4j.appender.File.appender.appender.layout.ConversionPattern=%d{ISO8601} |
%-5.5p | %-16.16t | %-32.32c{1} | %X{bundle.id} - %X{bundle.name} -
%X{bundle.version} | %m%n
log4j.appender.File.appender.appender.file=${karaf.data}/log/$\\{instanceId\\}/$\\{bundleName\\}.log
log4j.appender.File.appender.appender.append=true
log4j.appender.File.appender.appender.maxFileSize=1MB
log4j.appender.File.appender.appender.maxBackupIndex=10
This means we get different folders for different customers (instanceId) and
different files for different OSGi bundles (bundleName) within those folders.
This is a pretty sweet setup. To do the same in Log4J2, with XML configuration,
I had to do this:
<?xml version="1.0" encoding="UTF-8"?>
