Netflow Analyzer

Get a holistic view of your network with NetFlow Analyzer

NetFlow Analyzer PRTG lets you check and monitor your bandwidth and determine, for example, the amount of network traffic caused by IP addresses, protocols, or programs. In order to carry out such an analysis, you’ll configure your routers such that flow packets are sent to a computer with a PRTG probe. NetFlow technology puts little strain on your CPU and is especially adapted for networks with heavy data traffic and bandwidth.

NetFlow protocol is mainly supported by Cisco routers and switches.

With the PRTG NetFlow Analyzer you can get a holistic view about your network, keep an eye on your network traffic and what your bandwidth is being used for.

PRTG: A NetFlow analysing software, without any additional costs.


PRTG is an all-in-one tool! The monitoring tool requires no additional upgrade or tool to analyze your bandwidth using Cisco NetFlow. All it takes is a standard PRTG configuration and you’ll be on your way to monitoring the entire traffic which passes via your routers and switches.


With PRTG, you get one central software solution for all of your monitoring topics – and a complete overview. The need for a combination of many different tools is a thing of the past. PRTG lets you monitor your bandwidth use, server, CPU, traffic analysis, website, cloud services, and much more. And can be used as a professional NetFlow Analyzer software, as well.


PRTG uses an intelligent Auto Discovery to automatically set up comprehensive monitoring, and creates all the sensors you need. Switching from other NetFlow Analyzer software to PRTG therefore takes no time at all.


By default, Toplists in PRTG always split up the traffic analysis within the sensor among Top Talkers (bandwidth use according to IP address), Top Connections (according to connection), and Top Protocols (according to protocol). With Toplists, you’ll enjoy a categorized overview which makes NetFlow traffic analysis easy.
