Cool thanks. I got the idea then. Is there any way to do something
like that in the filter level or before it got to the appender? Also
how inefficient would it be to create the LoggingEvent? My idea would
be to only put this appender on certain classes if for instance there is
an exception we are trying to track down. It seems that based on the
code creating the LoggingEvent isn't very expensive since the string
isn't built until it is actually appended. So setting the Debug level
higher and having the Appender handle it wouldn't incur that much of a
performance penalty. Right?
