Hi Ceki,

Would you like to post it on this list for future reference?

I created a new discriminator taking the code of MCDBasedDiscriminator and modifying the method getDiscriminatingValue(ILoggingEvent event) as follows. public String getDiscriminatingValue(ILoggingEvent event) { Map<String, String> mdcMap = event.getMDCPropertyMap(); // If the MDC is empty return the default path if (mdcMap.isEmpty()) { return defaultValue; } String parentValue = mdcMap.get("parent"); String nodeValue = mdcMap.get("node"); return parentValue + "/" + nodeValue; } Cheers, Dario
