I need to set up a logging system for my java web application that not only logs the usual stuff (error message, error level, etc) but can also log additional information as well such as session ID. Sure I suppose I could put the session ID in the error message, but the problem is that I will end up logging lots and lots of data for lots of different users and I need to end up having a system where I can look at the log and sort the log based on session ID.
I’ve been looking at log4j coupled with chainsaw, and I think I could extend log4j to add additional attributes which is great, but then how do I view those custom attributes in chainsaw?
Surely i’m not the first one to have had this problem, is there something else I could use besides log4j coupled with chainsaw?
I don’t know chainsaw, but logging additional cross-cutting information such as session ids, user names, requesting ip, … is usually done through the nested diagnostic context.
