Great, SiftingAppender seems to be what I need, once I can configure it correctly Could you assist with rolling policy for it? I have a rolling policy that rolls over on size. Whether I put it in the sifting appender (<appendername="SIFT"class="ch.qos.logback.classic.sift.SiftingAppender">) or one of the generated ones (<appendername="FILE-${userid}"class="ch.qos.logback.core.FileAppender">) it seems to have no effect in either case. The rolling policy works fine in a separate FileAppender. Is it possible to add a rolling policy for a sifting appender, am I missing something? Thank you. ________________________________ From: ceki <ceki@qos.ch> To: logback users list <logback-user@qos.ch> Sent: Tuesday, June 12, 2012 4:00:28 PM Subject: Re: [logback-user] Split logs to different files by MDC? I'd suggest to re-write the expression as ((String))mdc.get("variable").matches("/test/") Are you familiar with SiftingAppender? It seems to address a use case similar to yours.

Hello
I have an application that has an mdc variable. How can I make a proper filter, so that if variable = test, all such output goes to one file, and to another file if variable is anything else?
I tried the following (not sure how to go from there even if it worked though):
<expression> mdc?.get("variable") ~= /test/ </expression>
but the result is
ERROR in ch.qos.logback.classic.boolex.JaninoEventEvaluator@7d55b9f - Could not start evaluator with expression [mdc?.get("variable") ~= /test/ )]
Any suggestions?
Thanks
