SiftingAppender replays elements found within <sift>...</sift> when it
creates a new appender instance. You probably do not want
SiftingAppender to do conditional configuration each time it creates a
new appender. As such, I would remommend to move the conditional part
outside the <sift></sift> element. Is that possible?

Oh wow, I actually haven't noticed that I just have FileAppender, not
RollingFileAppender
The 'home' property is defined higher up, so that part works well now
Thank you for the hint about debug, going to save a lot of frustration
Could you advise on how to use <if> with mdc values? What I'm trying is
the following:
I have this in my SiftingAppender:
<discriminator>
<key>variable</key>
<defaultValue>default</defaultValue>
</discriminator>
I want to determine the file name depending on the property, such that
(inside rollingPolicy):
<if condition='property("variable").equals("default")'>
<then>
<fileNamePattern>${home}/logs/generic-logs.%d{yyyy-MM}.%i.log</fileNamePattern>
</then>
<else>
<fileNamePattern>${home}/logs/${variable}.%d{yyyy-MM-dd}.%d{HHmm,aux}.%i.log</fileNamePattern>
</else>
</if>
At the moment the .equals check seems to fail all the time, and so the
1st fileNamePattern is never used. What am I doing wrong?

By the way, since the home property is used within SiftingAppender, it
should be defined in the "context" scope. Example:
<property name="home" value="/tmp" scope="context"/>
