We should review and simplify the default log4j configuration shipped with Magnolia. At the moment it logs in different files under MAGNOLIA_HOME/WEB-INF/logs, AND to catalina.out (or whatever container's default log file is), which is confusing. It seems people tend to look at the former when asked for logs, and those are mostly irrelevant in case of problems.

We should

• simplify the configuration (I'd tend to use a single file)
• provide (commented out or in a separate config file to be renamed) easy ways to get more logging for typical problematic cases

Also consider MAGNOLIA-18 and other log related issues.
