“The greatest advantage of PRTG? You get to rest easy“

Steffen Ille, Bauhaus-University Weimar.


Let our IP monitoring software work for you.
So you can concentrate on day-to-day tasks with total peace of mind.


PRTG automatically generates the optimal IP address sensors for your environment. In contrast to many other IP monitoring tools your monitoring will be set up and ready to go in no time at all. 92% of our customers report improved IT system reliability - thus saving them time and trouble.


Monitor your IP addresses comfortably, around the clock. And enjoy the design of an intuitive web interface. The built-in alert feature is quick to react - leaving no room for system trouble or failure.


79% 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 3 ½ months.

IP/network monitoring: why PRTG is the tool for you!

A convenient overview

With PRTG, you'll always know the score! Its central dashboard lets you see if everything is in the "green." As soon as problems or failures occur, the view immediately jumps to the "red". Thanks to our apps you get to stay abreast of the current status at all times - even when you're on the go.

Prompt and customizable alarms

PRTG features a built-in notification function. Its alarm is entirely customizable, which means you can decide to be alerted by e-mail, SMS, or page. Configure the alarm so you can be notified promptly – before system failures occur! By doing so, you will increase the reliability of your network.

A noticeable saving of time

Paessler regularly carries out customer surveys. One survey result: more than half of our customers indicate that they save two hours or more per week by using PRTG. Over the course of a year, this amounts to around 100 hours. Two full work weeks, which you can use to focus on more important things.

Your IP Monitoring AT A GLANCE

PRTG can be installed within minutes and it's compatible with most mobile devices.


IP Monitoring:
3 handy PRTG features


What is a Sensor?

Auto Discovery quickly identifies IP addresses

PRTG makes it easy for administrators to indicate which IP addresses are relevant. PRTG pings all IP addresses and automatically begins to monitor their associated devices. You will therefore save lots of precious time and can rest assured that everything is covered.

Overview Toplists

By configuring Packet Sniffing or NetFlow sensors, Toplists will automatically be generated in the sensor overview. Toplists contain three categories: top talkers, top connections, and top protocols. These lists enable you to identify the largest bandwidth consumers at a quick glance. You can even create additional Toplists. For more information, see our Toplists page.

200+ sensors make getting started a breeze

PRTG comes with over 200 pre-configured sensors. Among these are sensors for your hardware, bandwidth, website, and server. Check out our sensor list page for details. Sensors make getting started with PRTG - or switching from other monitoring software - both easy and convenient. And in general, setup takes no time at all - even for complex infrastructures. Our Smart Setup scans your network during the installation process and configures some initial monitoring as a starting point.


IP Monitoring
This is how you analyze your traffic with PRTG!

The starting position

As an administrator, you want to keep a close eye on your traffic. And for good reason: one single IP address can use up so much bandwidth that this can ultimately have negative consequences on your entire network. Thanks to PRTG, you will prevent traffic problems over the long term and optimize the performance of your network.

The overview

How much traffic runs via your network in all? The SNMP Traffic Sensor provides you with a summary of the total amount of traffic which comes in and goes out. Does the Christmas season put added pressure on your online store? Or perhaps marketing campaigns and major updates? With IP Monitoring by PRTG, you can identify weekly, monthly, and seasonal fluctuations. You'll see how traffic develops over longer periods of time, and can promptly take measures to accommodate scenarios such as continual growth.


Fine-tune your monitoring

Your next step is to have a look in greater detail. Via Packet Sniffing, or with NetFlow sensors for Cisco devices, you’ll be able to analyze your traffic more precisely and fine-tune your IP monitoring. The dashboard displays the amount of mail traffic, web traffic, file transfers, chat protocols, and much more. Where does such data come from? Who is the recipient? Which protocols are used? This fine-tuning lets you identify bandwidth hogs - whether they be individual users or certain applications or computers together.

The Swiss Army Knife for Sys Admins


Adapt PRTG individually and dynamically, to your specific needs, using the API:

  • HTTP API: Access monitoring data and manipulate monitoring objects using HTTP requests
  • Custom Sensors: Create your own sensors for customized monitoring
  • Custom Notifications: Create your own notifications to send alarms to external systems

IP Monitoring in PRTG Works as Follows:


Looking for an alternative to Nagios? Switch to PRTG!


Many users of open source solutions such as Nagios are in search of alternatives to their IP or network monitoring. It is true that the basic versions of open source software are free. But with PRTG, implementation and maintenance are significantly more straightforward, such as can be seen with the configuration of the customizable alarm and notification system. You'll therefore save time and worry - and in the long run, a lot of money. These costs should be taken into consideration when comparing the various tools available..


Open source solutions depend on the support of their communities - and that is a good thing. But when it comes to major problems, administrators need quick and reliable answers so issues can be clearly identified and resolved. Such assistance is provided by the PAESSLER Support Team. Our support team usually answers inquiries within 24 hours. The answers to many questions can already be found in our knowledge base. In addition, numerous videos and web seminars are at your disposal.


One of our greatest priorities is to make our monitoring software intuitive and easy to use. As an administrator, your job should be as stress-free as possible. The user-friendliness of PRTG has been repeatedly proven in countless consumer tests. For more information, read our comparison of Nagios and PRTG here.


Practical tip: “Hey Gerald, what would you tell administrators looking to implement their IP monitoring with PRTG?

„“Those wishing to set up IP monitoring should be ready to go in depth. Our SNMP sensors provide for a quick overview. But our Packet Sniffing and Netflow sensors ensure users get a closer look. Only then is it possible to optimize one’s network on a continual basis.”

Gerald Schoch works as a technical editor at PAESSLER AG.
