slf4j simple, is it possible to filter message within the same level?

Question

As titled, I just implemented slf4j simple here and I got a massive noise..

In that output, for example, I'd like to keep only the warns at the end, that is:

[pool-1-thread-1] WARN assimp.Assimp - Collada: No material specified for subgroup <> in geometry <*>.

Is there a way to achieve that?

Which logging implementation do you use? Because slf4j is just a facade. — guenhter, Nov 10 '17 at 17:32
@guenther The question says "slf4j simple", I assume it means slf4j-simple. — Alexey Romanov, Nov 10 '17 at 18:12

As documented in https://www.slf4j.org/api/org/slf4j/impl/SimpleLogger.html, you can start with following system properties (if I understood what you want correctly):

-Dorg.slf4j.simpleLogger.defaultLogLevel=error
-Dorg.slf4j.simpleLogger.log.assimp.Assimp=warn

Customize further to taste.
