Hi,

I have configured the sifting appender with a default value (unknown) for the discriminator, which generates a file called foo-unknown.log. But I would ideally like the appender to not output to any file when the discriminator via MDC has not yet been set. Any suggestions?

Thanks, G _______________________________________________ Logback-user mailing list Logback-user@qos.ch http://mailman.qos.ch/mailman/listinfo/logback-user
