PRTG Traffic Grapher – A great freeware tool

PRTG Traffic Grapher is an easy to use Windows software for monitoring and classifying bandwidth usage. It provides system administrators with live readings and long-term usage trends for their network devices. The most common usage is bandwidth usage monitoring, but you can also monitor many other aspects of your network like memory and CPU utilizations.

A very useful feature of PRTG that I noted is Analyzing of Cisco Netflow data streams. Visit following link to see all it’s features

PRTG uses both SNMP and packet sniffing or Netflow based monitoring. using the Packet Sniffer or Netflow based monitoring you can differentiate the traffic by protocol, IP addresses and MAC addresses

PRTG proves both freeware and commertial edittion. The freeware edition of PRTG Traffic Grapher is completely free for personal and commercial use and may be downloaded for free. You can monitore up to three sensors with it

If this link dos not work follow this

If you want to monitor more then three sensors then commertial edition is required which costs $62.50

Graphs generated by PRTG are very eye catching. Visit following link to see some screen shots
