How can I determine what log configuration source Logback actually used?

Question

log4j has a property, log4j.debug, which will helpfully provide the user with an indication of which configuration file was actually used to configure the loggi

Answer 1

you can set debug="true" in a logback.xml file that you control like this:

(...)

and tho make sure that file is going to be used by logback add following VM argument when you start your program:

-Dlogback.configurationFile=/path/to/yourlogback.xml

This does not really answer to your question but gives you a work around solution.
