That's pretty much my problem - LVS isn't a process, so how do I monitor it?

Maybe CPU is the wrong metric but throwing 500,000,000 connections/day
through a server has *got* to have some impact on its resources and I'm
looking for the right way to monitor how the server is coping.

All suggestions gratefully received!
