I am using Log::Log4perl in an application and I'd like to configure it in a way that it will log every call DEBUG or higher with limited information while calls that are ERROR or more serious will also include a stack trace. To include a stack trace I can add %T to the layout.ConversionPattern of the logger but so far I have not managed to configure it so both cases will work.

As a secondary issue, the %T tag prints the stack trace as a single line which makes it hard to read. Any idea how to convince the logger to print every level in the stack on a separate line?
