IP/network scanner:
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.
“The greatest advantage of PRTG? You get to rest easy.“
Steffen Ille, Bauhaus-University of Weimar, Germany
IP Monitoring:
3 handy PRTG features
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.
250+ sensors make getting started a breeze
PRTG comes with over 250 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. Whether you want to monitor IP addresses or your complete network - PRTG is the tool of your choice.

IP Monitoring
This is how you scan your traffic with PRTG!
An 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.

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, with NetFlow sensors for Cisco devices, or with other flow technologies like sFlow or jFlow, 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, VoIP, 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.
PRTG: The Swiss Army knife for sysadmins

A server is a computer or system that provides resources, data, services, or programs to other computers, known as clients, over a network. In theory, whenever computers share resources with client machines they are considered servers. There are many types of servers, including web servers, mail servers, and virtual servers.

Costs
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.
Support
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.
User-friendliness
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 use PRTG as a NetFlow Analyzer?”
“Cisco has continuously developed the NetFlow technology. Administrators must therefore find out beforehand which NetFlow version is supported by their routers and switches. With the right PRTG sensors, setting up NetFlow monitoring is quick and easy.”
Gerald Schoch, technical editor at Paessler AG
