nagvis ideas?

Our old monitoring solution was a product called solarwinds, 
the main view was a map which had little icons for various 
machines (it didn't monitor a lot more, great for monitoring 
all the interfaces on the network, but useless for system 
monitoring)

I felt the map was pointless. If something did break, you 
would get a little red dot in the corner. When I implemented 
Nagios I decided to ignore nagviz for a bit.

The only "map" I can see being off use would be something like

If you had a monitor hanging in the apps room. but even then, we rarely 
have hardware problems, and if we do, the machine will have a flashing 
red led. And even if we didn't, they're all labelled.

If you are truly physically seperated (not just different rooms in the 
same building, on the same power feed)

Could show you areas where there are invading tanks knocking out your 
infrastructure, but a network topology might be better. 

(Of course if you use nagios to monitor your country's defence systems, 
a physical map might be a good way of doing it)

1 of the 3 nagios installations I know about here have a default screen 
of "service problems". Our installation has a custom-written screen 
which highlights problems affecting users. The other isn't a real 
nagios installation, it was provided by an external company -- it barely

monitors hosts, and only does about 20 anyway, the statusmap is fine 
for that.

I'd be interested to know how many people find "maps" helpful for
anything 
other than impressing management.
