There are a couple of ways to control which logging events go into
certain files (more specifically, certain appenders).
You could specify named Loggers with package or class names in your
log4j config file such that output from certain packages or classes
are
printed to separate files.
You could also extend the Filter class and attach filters to your
appenders in your config file so that logging events are "routed" to
separate appenders / files depending on content, level... the
possibilities are endless with this approach.
We've been using custom filter classes to distribute log output to
several files based on NDC and MDC values. I was pleasantly surprised
to see similar ones added to the log4j-sandbox in recent months.
