Two PRTG sensors for analyzing IPFIX


IPFX Sensor

IPFX Sensor:
PRTG’s IPFIX Sensor captures IPFIX flow information, sorts this information by traffic type, and displays the bandwidth usage of each respective flow. The latter include chats, Citrix applications, FTP/P2P, email traffic, web traffic, and more. Data generated by other protocols (via UDP and TCP) is also displayed.

   IPFIX Custom Sensor


IPFIX Custom Sensor: The IPFIX Custom Sensor works in much the same way as the IPFIX Sensor. But with this sensor, you can also specify the types of traffic you would like to see in the sensor channels.

iWhat is a sensor?

In PRTG, “Sensors” are the basic monitoring elements. One sensor usually monitors one measured value in your network, e.g. the traffic of a switch port, the CPU load of a server, the free space of a disk drive. On average you need about 5-10 sensors per device or one sensor per switch port.

The advantages of using PRTG as your IPFIX collector and analyzer

Quick analyses

Quick analyses

If the network is overloaded (e.g. due to backups, load peaks, and the excessively high bandwidth consumption of clients and applications), you must be able to immediately see the cause, and take all the necessary steps to fix the problem. PRTG gives you a prompt overview so you can get to work at once.

High-performance tool

High-performance tool

PRTG is a comprehensive network monitoring tool used by more than 200,000 administrators worldwide. PRTG monitors all the systems, devices, and applications in your network, using a variety of technologies such as SNMP, WMI, packet sniffing, NetFlow, and IPFIX.

Built-in alarm

Built-in alarm

A PRTG license gives you direct access to all the software’s features, including the alarm system, reports, and technical support, as well as the full range of sensors. With PRTG, you get absolute transparency, and no hidden costs.

Quick setup

Quick setup

PRTG is configured in a matter of minutes. Its Auto Discovery function automatically creates the sensors you will need the most. And that means you can begin to take advantage of basic system monitoring from the very first time you launch the software.

Centralized tool

Centralized tool

PRTG is a one-stop monitoring tool. All-inclusive and chock full of options, PRTG lets you tackle potential network problems with just one tool instead of a mishmash of specialized ones. For example IPFIX: PRTG also offers sensors for packet sniffing, NetFlow, and other flow technologies.

An introduction to IPFIX monitoring with PRTG

IPFIX tutorial: Getting started with IPFIX monitoring

Step 1

Step 1

Install PRTG. In the free trial version, you can use every type of sensor, including IPFX and NetFlow sensors. The installation only takes a few minutes.

Step 2

Step 2

Open the menus of your IPFIX-compatible routers and switches. Configure the devices such that IPFIX data is sent to a computer running a PRTG probe.

Step 3

Step 3

Create the IPFIX sensors (corresponding to the target address) on the respective probe, then go into the sensor settings and specify the port and an IP address where you want the IPFIX flows to be captured. Choose the data traffic categories to be displayed by the sensor in the various channels. Optional filters make it possible to only include certain data traffic in the IPFIX analysis, or exclude it from the monitoring entirely.

iAn IP address (internet protocol address) is a numerical representation that uniquely identifies a specific interface on the network. IP addresses are binary numbers but are typically expressed in decimal form (IPv4) or hexadecimal form (IPv6) to make reading and using them easier for humans. Read more ...

What is IPFIX?

What is IPFIX?

IP Flow Information Export (IPFIX) is a protocol that was created by the IETF (Internet Engineering Task Force) as a standard for flow information. It was developed using the NetFlow system. The IPFIX standard determines how IP flow information is formatted and sent to an IPFIX collector or analyzer.

What kind of information does IPFIX send?

What kind of information does IPFIX send?

IPFIX is a push protocol that constantly sends monitoring data to a monitoring tool (like PRTG). This data includes information on traffic types such as chats, file transfers, email traffic, web traffic, and other UDP and TCP traffic.

Which manufacturers support IPFIX?

Which manufacturers support IPFIX?

Many router and switch manufacturers now support this technology, including Cisco, Citrix, Juniper Networks, VMware, Nortel, SonicWall, and more.

How does IPFIX work?

How does IPFIX work?

IPFIX data is sent from your routers and switches to an IPFIX collector. As a network monitoring tool, PRTG is also automatically an IPFIX tool which processes and visualizes this data, thereby allowing you to monitor the traffic in your network.

What is the difference between IPFIX and NetFlow?

What is the difference between IPFIX and NetFlow?

NetFlow was developed by Cisco, which means it is particularly suitable for Cisco devices. Technically speaking, the IPFIX protocol is an upgrade of NetFlow v9, and is sometimes even referred to as NetFlow v10. The IPFIX standard was designed to be manufacturer-independent. It is a universal protocol that can be implemented by any network device manufacturer.

What is the difference between IPFIX, jFlow, sFlow, and NetStream?

What is the difference between IPFIX, jFlow, sFlow, and NetStream?

NetStream is the protocol used by Huawei devices, while jFlow was developed for Juniper. These technologies are also extensions of NetFlow. With sFlow, which is used by scores of manufacturers, only every nth data packet is transmitted (“sampled flow”). As a result, less strain is put on your system. In general, monitoring software should support a variety of (flow) protocols to allow you to set up comprehensive monitoring for all the devices in your network. That is exactly why PRTG is so popular.

What is an IPFIX collector?

What is an IPFIX collector?

An IPFIX collector is monitoring software that can capture, process, and display IPFIX data. PRTG comes with two pre-configured IPFIX sensors. The IPFIX Custom Sensor lets you specify the information you would like to monitor.

What is the IPFIX port number?

What is the IPFIX port number?

The standard IPFIX port number is 4739. During setup, this port should therefore be left open. Tip: you can also use PRTG as a port monitoring tool to monitor or check bandwidth, traffic, and connections, or to see if certain TCP ports are open or closed.

What should I do if my devices do not support IPFIX?

What should I do if my devices do not support IPFIX?

Since IPFIX is a relatively new standard, it is only supported by a small number of devices. Find out which protocols are supported by your hardware. With PRTG, you can use NetFlow (v5 and v9) and flow technologies. Packet sniffing is another alternative for monitoring traffic.

Where can I find the IPFIX specifications?

Where can I find the IPFIX specifications?

The original requirements were published by the IETF in document RFC 3917. The basic specifications are documented in RFC 7011, RFC 7015, and RFC 5103.

IPFIX Collector vs. IPFIX Viewer vs. IPFIX Analyzer

Sysadmins often perform searches for IPFIX collectors, IPFIX viewers, and IPFIX analyzers, without really knowing which tools do what. An IPFIX collector is relatively straightforward: it collects IPFIX data. The same goes for an IPFIX viewer. An IPFIX analyzer, on the other hand, can be understood as a tool that goes into greater depth. Thanks to its easy-to-read monitoring display which lets you analyze your data traffic in detail, PRTG is much more than just a tool for collecting data.
