Hm, good point, I actually thought that feature is there, but that might have been a wrong assumption. The web console only let’s people filter the existing log…
Probably best to ask at the Karaf forum if people have a UI for log level management. It indeed might be tricky as it will depend on the used logging framework and Karaf leaves some choices to the user. Btw, once we upgrade to Karaf 4.1, we will also switch from log4j to log4j2, so any implementation that only works on log4j would break again as well…
