Java logging best practices about logger name

Question

I just ask about the logger name...

It it possible to give a custom name for a logger, or to use class name. But what to use in which case?

-> Using a custom name for each application module: some classes are used by 2 modules -> to which logger name should it belong to?

-> Using classname: it seems to require a good package organisation -> best practices for logging known about that?

Answer 1

I prefer using class names for the purpose of debugging. You can read the log trace (and the class name will be displayed) from the log file and view line code, etc. It's useful in that sense. If someone else maintains your code, they don't have to do hectic searches on finding where the "custom name" is populated (in which class).
