Lyra,
Whatsup allows you to monitor your network via icmp
and/or via other means (like snmp, ntp
http etc).
You are right, the traffic to monitor your network
also takes bandwidth on the network. The point is
that for local networks the bandwidth used is a
VERY small proportion of used bandwidth.
This can grow to a much larger proportion over WAN
links. The trade off is one of
using network bandwidth versus not knowing of
problems.
I'm sure there are lots of Network Management books
that go into this in greater
detail. Might be a better place for you to
start?
