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 management, but you can also monitor many other aspects of your network like memory and CPU utilizations.

Bandwidth and Network Usage Monitoring Made Easy
Monitoring Helps You To Optimize Your Network
With PRTG Traffic Grapher you will receive bandwidth and network usage data that helps to optimize the efficiency of your network. Understanding bandwidth and resource consumption is the key to better network management:
- Avoid bandwidth and server performance bottlenecks
- Find out what applications or what servers use up your bandwidth
- Deliver better quality of service to your users by being proactive
- Reduce costs by buying bandwidth and hardware according to actual load
Freeware Edition and Commercial Editions
The Freeware Edition of PRTG Traffic Grapher is completely free for personal and commercial use and may be downloaded for free. The Commercial Editions are required if you want to monitor more than ten sensors. Licenses for our bandwidth management software start at $295/€195.
See How Bandwidth Usage Monitoring Works
PRTG Traffic Grapher is running on a Windows machine in your network for 24 hours every day and constantly records the network usage parameters. The recorded data is stored in an internal database for later reference.
Using an easy to use Windows interface you can configure the monitored sensors as well as create usage reports. For remote access PRTG Traffic Grapher comes with a built-in web server to provide access to graphs and tables.
All common methods for network usage data acquisition are supported:
- SNMP: Simple Network Management Protocol is the basic method of gathering bandwidth and network usage data. It can be used to monitor bandwidth usage of routers and switches port-by-port as well as device readings like memory, CPU load etc. Go to animation....
- Packet Sniffing: With its built-in capability for Packet Sniffing PRTG can inspect all network data packets travelling in your LAN or WLAN to calculate the bandwidth usage. Go to animation....
- NetFlow: The NetFlow protocol is supported by most Cisco routers to measure bandwidth usage. Although being the most complex type to set up it is also the most powerful method suitable for high traffic networks. Go to animation....
Solutions using Packet Sniffing and NetFlow based monitoring PRTG can optionally calculate the bandwidth per IP address or port, e.g. to show the current Top Talkers, Top Connections and Top Protocols of your network.
The application runs on all Windows versions and works with most network products from Cisco, HP, 3Com, Linksys, Nortel, etc., and with various other devices (e.g. Windows PCs or network printers). More features...
