PRTG Network Monitor includes NetFlow sensors. Netflow can be used with most Cisco routers to measure bandwidth usage. Although it is the most complex type, NetFlow is also the most powerful router monitoring technology, and therefore suitable for high traffic networks. If you want to monitor Cisco devices using NetFlow, you need to change the setup of the Cisco router and tell it to send the Netflow packets to the machine running PRTG.
PRTG is an easy-to-use network performance monitor that analyzes bandwidth usage on networks. It lets you log the amount of data flowing through routers, monitor CPU utilization, check disk space usage and much more - and it only takes minutes to setup! PRTG is often used for checking leased lines, routers and firewalls, but there are also many other possibilities, such as monitoring managed switches, printers, or any other SNMP enabled network components.

The PRTG network monitor tools read the traffic data from your router and display the results in three graphs. This way you can easily see how much bandwidth has been used over the last 8-96 hours (kbit/sec), and transferred data counts for the last 14 days or for the last 12 months.
All you need to do now is decide which version of PRTG to go for! The Free Edition is available for commercial and personal use and doesn't cost anything at all. However, it does not support NetFlow monitoring. If you want to use NetFlow, and to use more than 10 sensors, you will need one of our commercial licenses.
