IMHO, it is BOTH sensible and possible. The latter part of that is
actually fact, not opinion. I monitor over 150 Cisco devices using
Nagios, as well as many HP switches, Nokia Firewalls, Windows and Linux
servers. I don't monitor printers, but other people do.

On my Cisco gear I monitor interface states, cpu usage, memory usage,
BGP sessions, environment variables (temperature and whatnot), bandwidth
usage (cooperation with MRTG here), and have written a plugin to backup
my router/switch configs to a tftp server.

I would guess everyone on the list has experience being completely new
to Nagios. However, the setup time involved will vary depending on the
user. Are you also completely new to Linux? If not, then I would bet
that it will take you a 'reasonable' amount of time. Just make sure that
you use the template config file setup, as this will save you a great
deal of configuration time.
