[logback-user] Split logs to different files by MDC?

[Yura Levandovskyy]

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 at 7d55b9f - Could not start evaluator with expression [mdc?.get("variable") ~= /test/ )]

Any suggestions?

Thanks
