AW: Cascading Services/Service hierarchy

James,

A simple answer to your questions is that VPO and Nagios offer the same
monitoring of hosts and services. What Nagios lacks is an ability to
generate a customer-facing report off the pages that the on-call person
receives that say "Hey, your web-server wasn't in a 100% working state
for 9.2 minutes last month." I'm not sure that there's an easy way to do
what you want, in either 1.2 or 2.0, without making a multi_check hack.
