Router Bandwidth Monitor

Analyze Your Bandwidth Usage With PRTG

How Does The Router Bandwidth Monitor Work?

PRTG Network Monitor allows you to monitor all the connections into the router and lets you discern how much bandwidth each connection is using.

The router bandwidth monitor uses the following methods to analyze network bandwidth:


  • SNMP monitoring is the basic method of gathering network bandwidth and network usage data. It works with with SNMP enabled devices, such as managed switches, routers and firewalls.
  • Packet Sniffing: With its built-in IP packet sniffer PRTG can inspect all network data packets travelling in your LAN or WLAN to calculate the bandwidth usage.
  • NetFlow: The NetFlow protocol is supported by most Cisco routers to measure network bandwidth usage. It is the most powerful of the three methods, suitable for high traffic networks.

Monitoring is both simple and intuitive, and can be done via a web based front end, the Windows GUI or even the iPhone interface. Data retrieval and configuration is easy, and the fully customizable web interface makes it easy to customize reports to suit your business.

Apart from bandwidth monitoring, PRTG Network Monitor also offers availability and uptime monitoring, website monitoring and can be used as a network load monitor, server performance monitor and for a network bandwidth test. PRTG is not only a LAN traffic monitor, but can also be used for monitoring wide area networks and VPN connections.

Download PRTG, the free network sniffer and monitoring solution now. The router bandwidth monitor is remarkably easy to install and runs on all Windows versions. In just a few minutes, you can begin to monitor network activity and bandwidth usage.

The PRTG router bandwidth monitor is available as fully functional 30-day trial license and Freeware Edition, which is completely free for personal and commercial use. The Commercial Editions are required to monitor more than 100 sensors or to monitor NetFlow.

Paessler also offers the advanced web load testing Freeware WebServer Stress Tool

Why Monitor Router Bandwidth?

Monitoring router bandwidth and network traffic should be an integral part of network management. By checking all connections into the router and keeping track of which applications or users consume most bandwidth you can identify bottlenecks in the network and allocate resources accordingly.

PRTG Network Monitor is Paessler's powerful network monitoring tool. Key features of the software include bandwidth measurement, uptime, server, and database monitoring, etc. More than 200 different sensor types put a variety of advanced monitoring options at your disposal: from basic PING sensors to advanced sensors for SQL server monitoring, or VoIP, router packet loss, and VMware monitoring. In addition, you can also create custom sensors using WQL. Therefore, PRTG is not only a router monitor, but also makes sure that your network components are available and working properly at all times.

How can I Monitor Router Bandwidth?

There are several possibilities for monitoring router bandwidth. If your router supports the Simple Network Management Protocol SNMP (which most network devices do), you can use SNMP to monitor the traffic going through your router, and analyse bandwidth usage by port.

If you want to filter router traffic or see which protocols or IP addresses consume most bandwidth, you can do so by using packet sniffing or NetFlow / sFlow / jFlow. These technologies employ top lists which show you top talkers, top connections, top protocols, etc, and let you define different rules for filtering router bandwidth traffic.

PRTG Network Monitor

PRTG is available in two editions. A basic free version with 100 sensors is available for download completely free of charge for personal and commercial use. The free network monitoring software supports all types of router bandwidth monitoring, i.e. it can even be used as a NetFlow Monitor. Need more sensors to monitor a larger IT infrastructure?
