Top Talkers is
the first screen I check every morning. It's a
good snapshot to help me see if the network is healthy
or if something is out of the ordinary. I can
watch protocols, see what traffic is work-related - sometimes its an easy problem like a bad NIC sending out
too much chatter. With Observer I can see all this
activity and proactively manage my bandwidth levels.
