Providing library defaults

Hello all,

I’m authoring a library that uses the Log4j API for internal logging. I want to provide my users valuable logging, but only under some circumstances. For example, if an expensive initializer gets called frequently, log a message indicating a possible performance impact. Or if logging something that may contain sensitive data, only logging it if they opt-in.

I would typically solve this at the application layer using Filters. A ThresholdFilter and a MarkerFilter for example. Is there a way to provide an additive default configuration for my users? Or some other mechanism for saying “don’t log by default”? Or perhaps differently, am I wrong for thinking about the problem/solution this way?

Thanks in advance!


Cheers,
Marius
