caching...

[Alan Brown <ab...@opstechnology.com>]

I'd like to only log debugging messages if a warning or error occurs
shortly afterwards.  In the past I've written my own logging systems
that have cached messages and then logged the last x debug messages to
file if an error occurs.

Is there a way to do this with Log4J or would I have to write my own
caching mechanism in front of the logger?

Most appender support the BufferSize property which
does exactly what you describe.  Beware that in order
to ensure that the buffer get cleared when the system
exits, you generally have to make a call to
LogManager.shutdown().
