Thanks again for your help. But now I am at a bit of a loss. If the sink
class on the server side or on the client? I assume it was on the client
side, but as per you code it appears to be on the server side.
Also, I notice that you are not using the same pattern I use to log events.
I just use the basic log.Info(...) and the reason I though it would be a
good idea to use the remote appender is because I don't have to change the
code (over 2 milion lines of code with lots of log.info) and handle
everything by adding the new appender to the configuration file. Am I
completely wrong?
