For instance, suppose I want to drop the level of all log messages in the
parent logger "org.example.project" by one priority except for error. So
this would map WARN -> INFO, INFO -> DEBUG, etc. I'm not exactly sure on a
DSL here, but it's more of a thought than a feature request right now.

I’d have to see an example to understand the benefit. As it is right now you have to configure a logger for each thing you want to manage at its own logging level. If you were going to “re-write” the logging level how would you do that without having to configure each logger with the new level? The only difference I can see is that the level in the output would now be different than what is specified in the code.

What I'm suggesting is remapping the levels before they're filtered. That's
just for the output format.

We have LoggerNameLevelRewritePolicy.

Re: Discussion about logging on Reddit

The conversations there make me think that some sort of ability to rewrite
log levels emitted from various loggers at configuration time could be
useful. For instance, some libraries are rather spammy in the info or warn
level, and having to suppress all non-error messages from those frameworks
doesn't seem like an ideal way to configure things. It could be more
complicated than it's worth, however.

Interesting comments. In the typical reddit fashion, I propose a Buzzfeed
listicle on logging based on the thread. Or at least some manual
enhancements.
