You probably have the list of the most commonly used. Each has good and bad points. A few of them I believe are limited on using agents and supporting external scripts. Several are considered Nagios on steroids, using a Nagios core wrappered in a bunch of other OSS. Several, like Zenoss are particular about the primarily monitoring system (though agents might run on any OS). Jack
