Hi All, What unclear point here is how to use two log4j.properties files in same pack. Because even if you started any carbon related server with profiles means it's starting the same pack with same configuration files. Only difference is features which are activating at the runtime is different. In the build time we copy log4j.properties file to repository/conf folder. So if you want to use the two log4j.properties files where are you going to keep those 2 files and how are you going to specifically tell to the carbon server to use this file when start with this profile? I think this would be code changes in the carbon level and cannot do because this is a specific requirement to MB. What can do is at the runtime copy different log4j.properties file to the above location using the wso2server.sh file keeping those in the different location. I think this is not an elegant way to achieve this. But can't we achieve this using the same log4j.properties file ? I think we can combine all the appenders to the same log4j.properties file. Even MB started with profile or standard alone mode, in each time cassandra or zookeeper features activated. So it would be helpful users to see the logs in both ways.
Cheers!
