At the risk of making announcements too soon, I'm working on a tool right
now that will do this sort of monitoring for MV environments - in
collaboration with or instead of products like DPMonitor.  A VAR or IT staff
can automatically monitor remote client systems for OS, DBMS, or Application
issues, and get notifications when action is required.  This allows support
providers to be more pro-active, and adds new levels of service options for
everyone.  Another feature will allow system updates along the lines of
Symantec LiveUpdate or RedHat Network Management, and other forms of remote
maintenance to eliminate the need for people to manually update hundreds of
systems.  There's a LOT more being built into this but it's too early to go
into detail at this time.

E-mail inquiries are welcome, especially from people who feel the pain of
supporting a large number of sites.
