Naming loggers / resolving calling classes

[Jonathan Whitall <fi...@yahoo.com>]

Hello,

I have a problem.  In my logging message, I want to be
able to output the name of the class that initiates
the logging, i.e. the caller, with something similar
to this:

[2003-04-08 19:57:40,019 INFO] com.mycompany.MyClass: 
message

I cannot afford to use the %C option for
PatternLayout, because it really is a performance hog
(it was taking 300ms for one logging statement!)  The
only other option that I can think of is to
instantiate separate loggers for each class by using
the class name as the logger name, and then using %c
in the conversion pattern instead of %C.  I have seen
this done in a few examples.  Is this considered best
practice, or are there serious performance
considerations with getting separate loggers like
this?

Thanks,

Jonathan Whitall
