PRTG makes monitoring via IPFIX easy

Custom alerts and data visualization make it easy to monitor, identify, and prevent network traffic and bandwidth issues.










4 reasons to choose PRTG as your IPFIX monitoring tool

In an ideal world, you want your network to run smoothly, efficiently, and securely. One way to make this happen? Monitor the traffic on your routers, switches, and firewalls with one of Paessler PRTG’s flow-based monitoring technologies, leveraging the IPFIX protocol.

Set up IPFIX monitoring quickly & easily

If you are in no mood for complicated configuration work, PRTG has got you covered.

Our preconfigured IPFIX sensor, which you can add to your monitoring setup in just a few clicks,  captures IPFIX flow information from the device you want to monitor and shows you the top talkers, connections, and protocols in your network, next to other metrics.

Identify traffic issues effectively

Use our IPFIX monitoring tool to track traffic patterns, bandwidth usage, and more to ensure optimal network efficiency.

PRTG helps you to quickly pinpoint and address issues like an overloaded network – for example, due to backups or excessively high bandwidth consumption – even before they escalate.

Analyze and optimize network performance

Optimize your network's performance by leveraging PRTG’s powerful IPFIX reporting capabilities. PRTG provides you with a wealth of historical data for in-depth IPFIX traffic analysis.

This way, you can make informed decisions on bandwidth resource allocation or other actions that make your network faster and more reliable.


Ensure network security and compliance

Secure your network against threats by keeping tabs on suspicious network traffic using IPFIX.

With PRTG, you can stay on top of network anomalies like unusually high bandwidth usage or heavily used connections, which might point to unauthorized access or DDoS and other network attacks.

Monitoring via IPFIX: FAQ


1. What is IPFIX?

IPFIX, or IP Flow Information Export, is a format standard established by the Internet Engineering Task Force (IETF) for sending flow information. It evolves from Cisco's NetFlow system and outlines how to format and transmit IP flow data to a collector or analyzer for such information. IPFIX monitoring provides detailed insights into traffic flow, device performance, and network utilization.

2. What type of data does IPFIX transmit?

IPFIX operates as a push protocol, continuously forwarding a variety of monitoring data to tools like PRTG. This includes diverse traffic types, encompassing everything from chat and file transfer activities to email and web traffic, also using other protocols like UDP and TCP.

3. Who are the providers of IPFIX-compatible equipment?

IPFIX is supported by a wide array of router and switch manufacturers, including well-known names like Cisco, Citrix, Juniper, VMware, or SonicWall, among others.

4. How does IPFIX function?

IPFIX gathers data from your network devices, such as routers and switches, and forwards this information to an IPFIX collector. In the context of network monitoring, PRTG acts as an IPFIX analyzer, analyzing and visualizing this data to help you oversee your network traffic.

5. What is the difference between IPFIX and NetFlow?

While NetFlow is a Cisco-originated protocol and works best with their devices, IPFIX is essentially an advanced version of NetFlow v9, sometimes referred to as NetFlow v10. Unlike NetFlow, IPFIX is designed to be universal and manufacturer-neutral, making it adaptable for various network devices.


6. What sets IPFIX apart from jFlow, sFlow, and NetStream?

NetStream is specific to Huawei, while Juniper uses jFlow. sFlow, adopted by numerous manufacturers, transmits sampled data, thus reducing system load. Effective monitoring software should support these varied protocols, as PRTG does, for comprehensive traffic monitoring across a network.

7. What is the difference between an IPFIX collector, an IPFIX viewer, and an IPFIX analyzer?

An IPFIX collector is software that captures, processes, and presents IPFIX data. The same goes for IPFIX viewers. An IPFIX analyzer like PRTG goes deeper and looks at IPFIX flow data in more detail, displaying, for example, the bandwidth usage of each respective flow.

8. Which port is used by IPFIX?

IPFIX generally uses port 4739. It's important to keep this port open during setup. Additionally, PRTG can also function as a port monitoring tool, helping you oversee bandwidth, traffic, connections, and the status of specific TCP ports.

9. What if my devices don't support IPFIX?

As not all devices support IPFIX, check what protocols your hardware supports. PRTG enables you to use other flow technologies like NetFlow (v5 and v9), packet sniffing, or SNMP as alternative technologies for monitoring your network traffic.

10. What is a sensor in PRTG?

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.
