There is support exactly for this type of situation. See the docs for PatternLayout [1]. In particular, the docs on %ex conversion word. Here is the relevant quote:
This conversion word can also use evaluators to test logging events against a given criterion before creating the output. For example, using %ex{full, EX_DISPLAY_EVAL} will display the full stack trace of the exception only if the evaluator called EX_DISPLAY_EVAL returns a negative answer. Evaluators are described further down in this document.
Refer to [2] for evaluators.
Let us know if this approach works for you.

Well, how could it not work? I changed my config to: <evaluator name="CALLER_EVAL" class="ch.qos.logback.classic.boolex.OnMarkerEvaluator"> <marker>MY_MARKER</marker></evaluator>...<pattern>... %n%xThrowable{full, CALLER_EVAL}%caller{5, CALLER_EVAL}</pattern> Just what I need. Sorry about this RTFM. Thanks, ceki.
