Let me preface this question by saying I've exhausted Google, or at least what I've been trying to search for. "log4j threshold", "log4j threshold category", "log4j appender threshold category", etc. But I really don't understand the results I'm getting back from Google.

This is the full configuration I've been given. I can't figure out how to modify it to suit my needs.
