This is a useful tool for network managers. It’s very
useful in scenarios where all users access Internet through a proxy and the
network administrator wants to monitor Internet usage. The tool shows traffic
from all available network connections and displays real-time bandwidth usage
graphically. Bandwidth Monitor lets you monitor all types of traffic on both
WAN and LAN. In addition, you can set alerts, if a particular connection exceeds
the threshold limits for data transfer. 

Bandwidth Monitor works with all types
of network connections including phone modems, DSL, cable modems, LAN,
satellites and more. You can install this tool on a Windows machine running
proxy services. After installation, it will show a graphical bandwidth
graph on your screen. In order to configure the tool, just right-click the
graph and select the options that you want to configure.
