Simplest way to extend your logs with domain information is to use DomainLoggerContext instead of the defualt one:
LogManager.context = new DomainLoggerContext(TopLevelDomain.DOMAIN);This way default messageFactory for every logger will become a DomainMessageFactory with specified domain.
Essentially a copy of a standard TraceEverythingConfiguration but using DomainLayout for the trace target.
Creates a IMessage instance implementation which contains a domain information. Messages created by this factory implement IDomainMessage interface which is extension of standard IMessage.
Basic implementation of a layout which deals with the additional domain information. Not that fallback behavior is necessary because not every message is IDomainMessage.
Basic implementation of a filter that handles domain information. For the same reason as DomainLayout filter has to deal with potentially missing the domain information.
