There are 2 major issues that we still don't cover: - No HA for monitoring, who checks the hosts when the engine is down. - No scale - the engine is a bottle-neck in network and compute. Although the above is a huge arch change, we need to start somewhere, this feature sounds like a candidate to introduce it. About the examples: http://sixrevisions.com/tools/10-free-server-network-monitoring-tools-tha... The main goal of the feature if my suggestion is taken, is to select to most appropriate one. Thanks, Gilad.
