Is it possible to have different log levels for different applications/modules?

Example implementation: onkel-dirtus/logger_file_backend as it was mentioned in

Configuring Logger on Umbrella

I think the only way you would achieve this is to use a custom backend, and then use the :application or :module metadata keys to do something with it. Backends like https://github.com/onkel-dirtus/logger_file_backend has a metadata_filter config option that you can use to filter out messages to certain files. Alternatively if you want it in a console, it shouldn’t be that hard to knock up what you need: Copied the main Logger.Backend.Console from https://github.com/elixir-lang/elixir/blob/…
