This is about openHAB 3.2 which uses Karaf 4.3.4 and Pax logging.
The idea is to put data into an MDC in a bundle and use it for log4j2 routes.
I tried this in a Java main sample and it works:
MDC.put("ohtopic", "openhab/items/XLevel/state");
<Routes pattern="$${ctx:ohtopic}">
<Route key="openhab/items/XLevel/state" ref="FILE1">
</Route>
But not within openHAB / karaf, there only the bundle id etc. appear
in log4j2 (as shown with %X pattern).
Thanks,
Juergen
