NetFlow is a protocol for collecting, aggregating, and recording traffic, or flow* data, in a network. This data provides a more granular view of how bandwidth and network traffic are being used when compared to other solutions.
The protocol was developed by Cisco and is embedded in Cisco’s IOS software on the company’s routers and switches. Many other hardware manufacturers either support NetFlow or use alternative technologies.
* A flow is simply a way of grouping a unidirectional stream of packets into a specific set. These sets can be configured according to matching attributes in each packet including IP source, IP destination, source port, and others.
A NetFlow collector captures, saves, and processes NetFlow data. It’s an application that ingests the flows and organizes the binary data into a numeric format. A NetFlow collector also compresses the size of the NetFlow data and stores the output on a database.
Some of the tools out there are more effective than others at providing in-depth data analysis. And many administrators use one single tool to perform the functions of both a NetFlow collector and NetFlow analyzer – such as Paessler PRTG, the all-in-one monitoring tool for your network.
PRTG is designed to scale efficiently with your network. It utilizes an optimized database architecture and intelligent data sampling techniques to handle high volumes of data without degrading performance. For larger networks, PRTG can distribute monitoring loads across multiple servers to maintain responsiveness and real-time monitoring accuracy.
Yes, PRTG allows users to set up customized filters for NetFlow data, enabling you to focus on specific IP addresses, port numbers, or traffic types. This capability is crucial for finding the root causes of issues or monitoring specific aspects of network traffic, such as multicast or peer-to-peer traffic.
PRTG enhances network security by providing detailed traffic analysis, which can detect anomalous behavior and potential network attacks. Features include encrypted data storage, secure communication channels between sensors and the core server, and comprehensive logging of all network events, which is crucial for forensic analysis and compliance with regulations like GDPR and HIPAA.
There is a reason why 500,000 users rely on PRTG every day, the monitoring solution for all areas of IT, including database, application, cloud, server, LAN, and SNMP.

PRTG offers extensive native support for popular network devices and applications and a powerful API for custom integrations. This flexibility allows PRTG to fit into any IT infrastructure and interact seamlessly with other management tools and systems, streamlining workflows and enhancing data consistency across your monitoring toolkit.
In PRTG, “sensors” are the basic monitoring elements. One sensor usually monitors one measured value in your network, for example the traffic of a switch port, the CPU load of a server, or the free space on a disk drive. On average, you need about 5-10 sensors per device or one sensor per switch port.
Paessler conducted trials in over 600 IT departments worldwide to tune its network monitoring software closer to the needs of sysadmins. The result of the survey: over 95% of the participants would recommend PRTG – or already have.
