Hi Ceki, It is (kind of) clear. The only part I have problems with is: "...Place logging events in a queue, and if the queue becomes full, drop new events..." How exactly I'd do this? Do I have to implement some method that "drops new events if the queue becomes full" or there's already something built-in.
You would need to modify AsyncAppender so that instead of blocking, it drops events. I would think that it would be a fairly easy modification to make.
I know that (From the Log4j Manual: "...If however the queue is full, then AsyncAppender.append() will not return until free space becomes available." ) So if the queue becomes full the dispatcher thread will try to free the space by removing the oldest events from the queue and dispatch them to each attached appender but if the only appender is the SocketAppender that can't process anything at the moment, since there's no comunication to the server, what's going to happend?
Events will be dropped. (You can't have your cake and eat it too.) -- Ceki Gülcü Logback: The reliable, generic, fast and flexible logging framework for Java. http://logback.qos.ch
