Even in a regular corporate environment, a single Nagios administrator
is a bottleneck. If you work with other people and they have to make
requests to have updates made, you could benefit from some form of
discovery.

I think their Cisco templates are very good. CPU/Memory statistics,
model detection, in addition to all the normal port data. You only
give Torrus the IP address, it must figure out the rest.

Templating is the first step toward a discovery solution. Next after
templating comes automatic creation and discovery. ;]

Thanks.
