Hey Dan,
Basically we have a few servers at out remote sites, all connected to head office with VPNs. What I am basically monitoring for the time being is whether the server is up or down. In Hyperic 4 as soon as the VPN dropped off, I would get an email notification and the Hyperic HQ Dashboard would show 0% availability. However what I am finding now, is that this is not the case. For example about half hour ago I purposely killed a VPN at one of the sites, and the HQ Dashboard still shows up 100% availability and not notifications are being sent.
