standard uses of log4j's 5 levels
I'm currently doing a research on the standard usage of the 5 levels of Log4j. My question is that is there a standard convention of which level to use when we program? Like should we use DEBUG more often than INFO? I understand that there are certain circumstances which require us to use a specific level. However, how about when we don't have the special cases; which level do we use usually (esp. when we write programs at the production level)? Is there a general concensus/convention/standard?
Also, what is a good approach/standard for logging entry and exit of the method?
I know that this might be a quite specific question. I'm also trying to find out what other programmers/companies are doing...(do they have a standard way of using it?) But It seems really hard to find exact information I'm looking for. If anyone could offer some outlets for finding the solutions to my question, that'd be great. Thank you.
