[logback-user] CONTEXT_NAME property with DBAppender

Hi, I'm using a DBAppender and when I log something, I see that a LOG_EVENT_PROPERTY row with MAPPED_KEY = 'HOSTNAME' is inserted with the LOG_EVENT. Is there an option (in configuration) to make the CONTEXT_NAME visible too in the same way when using a ContextSelector or do I have to put it myself in the MDC through a Servlet Filter?  Regards, Xavier
