Traffic characteristics for the last 1 second, and the average and peak
values since the test began:
Utilization: Percentage of the network's bandwidth used. This indicates
the traffic density on the network. Utilization averaging over 40 % may
indicate a problem.
Collisions: The percentage of collision frames as compared to the total
number of frames detected in the last 1 second. Collisions occur when
two devices attempt to transmit at the same time. A collision rate
averaging over 5 % may indicate a problem. A full-duplex link should
show 0 % collisions.
Errors: Includes short frames, bad FCS (frame check sequence), late
collisions, and jabber. An error rate above 0 % indicates a problem.
Broadcasts: Percentage of frames addressed to all devices. Acceptable
broadcast rates vary among networks.
