Check out the NDC(Nested Diagnostic Context) in log4j for this <quote> The NDC class implements nested diagnostic contexts as defined by Neil Harrison in the article "Patterns for Logging Diagnostic Messages" part of the book "Pattern Languages of Program Design 3" edited by Martin et al. A Nested Diagnostic Context, or NDC in short, is an instrument to distinguish interleaved log output from different sources. Log output is typically interleaved when a server handles multiple clients near-simultaneously. Interleaved log output can still be meaningful if each log entry from different contexts had a distinctive stamp. This is where NDCs come into play. Note that NDCs are managed on a per thread basis. NDC operations such as push, pop(), clear(), getDepth() and setMaxDepth(int) affect the NDC of the current thread only. NDCs of other threads remain unaffected. </quote> from http://jakarta.apache.org/log4j/docs/api/org/apache/log4j/NDC.html > > Ex: you are running a system, something is wrong, if you look at the logs > you see 254 threads going through and the messages make no sense.
