LogFaces is created to be an out-of-the-box log server which can be easily hooked with existing applications using log4j as their logging framework. "Off the shelf" is the major feature - you simply install it next to your system and redirect your appenders to logFaces server; it works with TCP or UDP sockets - both well supported by log4xxx. It's up to you which processes, hosts or even classes should be working with logFaces- thanks to log4xxx configuration magic, all this is very simple and not intrusive.
