nicstat

print network traffic statistics

nicstat is to network interfaces as iostat is to disks, or prstat is to processes. It is designed as a much better version of "netstat -i". Its differences include: - Reports bytes in & out as well as packets. - Normalizes these values to per-second rates. - Reports on all interfaces (while iterating) - Reports Utilization (rough calculation as of now) - Reports Saturation (also rough) - Prefixes statistics with the current time
