PRTG sensors for analyzing data packets
i NetFlow is a protocol for collecting, aggregating and recording traffic flow data in a network. NetFlow data provide a more granular view of how bandwidth and network traffic are being used than other monitoring solutions, such as SNMP. NetFlow was developed by Cisco and is embedded in Cisco’s IOS software on the company’s routers and switches and has been supported on almost all Cisco devices since the 11.1 train of Cisco IOS Software.

PRTG lets you monitor IP packets and filter according to UDP and TCP packets, for example. The following PRTG sensors will allow you to capture packets:
Packet Sniffing Sensor
With the Packet Sniffing Sensor, you can monitor web traffic, mail traffic, file transfer traffic, infrastructure traffic, and remote control traffic, among others. The sensor only analyzes the headers of data packets, and therefore puts little strain on your system. To the Packet Sniffer Sensor.
The NetFlow protocol is mainly used by Cisco devices. PRTG comes with corresponding NetFlow sensors. Whether NetFlow V5, NetFlow V9, or IPFIX: PRTG has sensors for Cisco routers and switches that can handle any future developments. To the NetFlow sensors.
sFlow sensors only check every nth packet. You will therefore put even less strain on your network. These sensors are especially suited for extremely large networks, where reducing the network load caused by monitoring is a must. To the sFlow Sensor.
NetFlow, IPFIX, jFlow, and sFlow sensors are also available as custom sensors. These sensors can be configured to serve as individual channels or to monitor the data traffic you wish to analyze. As a result, you can pinpoint your troubleshooting. To the Flow-sensors.
... more than sensors
You'll find over 200 sensors in our sensor list. These sensors are part of a single, centralized tool that allows you to perform comprehensive monitoring and capture data traffic. With PRTG, you’ll keep a constant eye on your entire network. Our sensor list is continually being updated.
PRTG is a vital tool for getting your IT into tip-top shape!
The costs for a one-year PRTG license pay for themselves in an average of only a few weeks.
License costs vary according to the size of your network.

PRTG saves network management costs
PRTG saves time spent on network management
Keep a constant eye on your network –
even while on the go
PRTG can be started within minutes and it's compatible with most mobile devices.
Six advantages of PRTG
While configuring PRTG, the Auto Discovery feature is launched automatically. This feature searches all the devices in your network, and creates sensors for monitoring them. Basic monitoring is therefore configured during the setup process, and available when opening PRTG for the very first time. This saves you time and hassle. Initial results, furthermore, are displayed immediately.
Custom sensors allow you to choose the types of data you wish to capture. For example, you may opt to only analyze HTTP or file transfer traffic. You can also just have certain servers or devices displayed. As a result, you will pinpoint your troubleshooting.
All important facts and figures are displayed in an easy-to-understand, customizable dashboard. Whether on your desktop, smartphone, or tablet: PRTG is always available! Have a look at some examples of dashboards.
Toplists for the overview
Each sensor automatically provides “toplists.” View the top talkers, top connections, and top protocols at a glance. You'll maintain a constant overview, and can subsequently perform an in-depth packet analysis or diagnosis.
PRTG lets you capture data traffic over a longer period of time, and then analyze this traffic. You’ll therefore detect long-term anomalies, such as an abnormal increase in certain protocols or data types in the total traffic at certain times or on specific days.
One tool for a variety of manufacturers
Whether a Cisco router, Juniper switch, or Microsoft server: PRTG has the right sensors for your network. Benefit from one central monitoring tool instead of a handful of separate solutions. PRTG lets you monitor total traffic as well as individual data packets.
Network: Where do I monitor data packets?
Video tip: How to monitor bandwidth with packet sniffing and flow technologies
Capturing packets on the router
Connect PRTG to the monitoring port of a router or send flows to PRTG and use corresponding sensors to capture all data packets which pass through it. This procedure is the most common one.
Capturing packets on the switch
You can also use sensors to monitor data packets on an individual switch.
Capturing packets with VMware
PRTG monitors your virtual infrastructure by way of port mirroring on routers or access points. You will subsequently see which and how much data your ESX server sends and receives.
Capturing packets on the server
With PRTG, you can limit packet capture to individual servers. This is appropriate for email and web servers, for example.
PRTG simplifies your day
Our monitoring software works for you and promptly notifies you of potential issues.
It frees you to concentrate on your day-to-day tasks with peace of mind.
PRTG saves time
With PRTG, you get one central monitoring tool for analyzing data packets. The dashboard provides a quick and concise overview at all times - whether on your desktop or as an app.
PRTG saves worry
Configuring PRTG is quick and easy. Getting started or switching from another network monitoring tool is easy thanks to more than 200 predefined sensors.
PRTG SAVES MONEY
80% of our customers report substantial or even exceptional network management cost savings. Our customers report that their PRTG licenses have paid for themselves in an average of a few weeks.
Data packets: Definition & tools
Data packets make it possible for data to be communicated via the Internet. They are sent via all the usual protocols. TCP packets are extremely reliable during the exchange of data, as errors are checked for and eventually removed. With UDP packets, the focus is on the quick exchange of data. PRTG monitors IP, TCP, and UDP packets, as well as other protocols.
Packet capture tools
Many administrators use Wireshark to analyze their data packets. This tool, however, has the disadvantage that all information is captured live and unfiltered. This makes analyses difficult to perform as there is no clear indication of where to start. Although the tool provides an in-depth look, it does not come with an overview. PRTG takes a different approach. It lets you filter data packets according to various properties to detect potential problem areas, and then check these areas in more detail. By doing so, you'll get to the root of problems faster and more easily.
