Actually Chainsaw is pretty lightweight compared to everything else :-)

You didn't say what exactly are you trying to achieve, so I would assume
that you want to monitor your logs from remote control point. If what
you need is to log messages on remote server - just use the
SimpleSocketServer from log4j.

A very good log management tool is XpoLog (xplg.com) Recently I've been
seeing all these ads for Splunk, so you might want to check it as well.

If what you need is monitoring and management, Tibco Hawk is a good one
and not as expensive as most of the others NMS-es. Even cheaper
(actually free ;-) is OpenNMS.
