<p>Hi,</p>
<p><br>
</p>
<p>we are using the sift logger (with MDC) to separate log entries generated by user actions from log entries generated by "background" tasks. That works nicely.</p>
<p><br>
</p>
<p>However, now we want to have different log levels for these two appenders (e.g. DEBUG for "foreground.log" and WARN for "background.log"). Problem is that there is obviously only one appender. Can that be accomplished within the logback.xml?</p>
<p><br>
</p>
<p>For reference, here is our current logback.xml</p>
<p><br>
</p>
<p><configuration scan="true" scanPeriod="30 seconds"><br>
<appender name="SIFT" class="ch.qos.logback.classic.sift.SiftingAppender"><br>
<discriminator class="ch.qos.logback.classic.sift.MDCBasedDiscriminator"><br>

<defaultValue>foreground</defaultValue><br>

<appender name="FILE-${stream}" class="ch.qos.logback.core.rolling.RollingFileAppender"><br>
<file>${destination}/${stream}_current.log</file><br>
