The higher any value, the more load on network and NWM system

Have a look at Nagios. Really. We use(d) it very successfully within our
managed service group. The grouping feature helps A LOT. For mission
criticals the two-stage alerting is nice, too. 

Web-based it is usable from "anywhere" (client independent). You even
can create a "status wall" with a rack/shelf and serveral PCs/monitors,
each one showing a different group status page - add one or two beamers
für Houston feeling...

Depending on grouping you can see "onf of the Radio-Bridges RED" or:
"something in Alaska YELLOW". A map often is waaay to small for a "real
world" environment to see anything. 

But a (zoomable) map is a standard "can do" in

I guess you thought of SNMP here...

Have a look at Nagios (http://www.nagios.org/) and Cheops
(http://www.marko.net/cheops/) before starting at ZERO again. 

BigSister (http://bigsister.graeff.com/home.html) and BigBrother are
probably a leage below your requirements as they do not offer (IIRC)
a grouping that's compact enough.

Checks should be highly configurable (ping one router, read nearly all
SNMP from the next), should support grouping in configuration (i.e. done
once for all 7205's, once for all Sun E450s etc.) and display. Nagios is
nice here - again.

Have a DEEP look and some hands-on tests with Nagios before rolling your
own. I've not tested Cheops, but it looks a bit like what you have in
mind, too.
