Architecting Modern Java EE Applications

Logging and tracing

Historically, logging had quite high importance in enterprise applications. We have seen a lot of logging framework implementations and supposedly best practices on how to implement reasonable logs.

Logging is typically used for debugging, tracing, journaling, monitoring, and outputting errors. In general, all information that developers consider somewhat important, but not made apparent to the users, is been placed into logs. In almost all cases, this includes logging to files.
