So if a request needs to be marked as CONFIDENTIAL and as DATABASE, you would create a new marker referencing both.
Marker m = MarkerFactory.getMarker("COMBI"); m.add(MarkerFactory.getMarker("CONFIDENTIAL")); m.add(MarkerFactory.getMarker("DATABASE"));
logger.info(m, "Donald Duck withdrew 1'000 rupees");
Ouch. That's not obvious just from looking at the API. Just to give you an idea of what I have in mind: http://bit.ly/cOsi2W Actually, I separated logging from tracing. I even went so far and replace log levels with tags. A developer just adds tags. In the end you have rules/filters configured by an administrator which decided about the importance of a log message at runtime. The reason is that I often found code where developers just didn't care about correct log levels but mixed debug with info, etc. Logging can also be very useful for business events. That's when you need structured and rich data. But debugging/tracing doesn't need rich data. Thus, I thought about such a drastic split between the both and also forced such a split in the APIs. -Gunnar -- Gunnar Wagenknecht gunnar@wagenknecht.org http://wagenknecht.org/
