System Requirements for
PRTG Network Monitor

To install and work with PRTG Network Monitor you need:

  • A current PC or server with at least a dual core CPU and minimum 2048 MB RAM memory
  • Microsoft® Windows 7 or later (server or workstation, 32 or 64 bit)
  • Web browser Google Chrome 42 or later (recommended), Firefox 37 or later, or Internet Explorer 11 to access the web interface

Large installations of PRTG require a more careful planning. You can find more information as well as detailed requirements for monitoring with SNMP, WMI, Flows, Packet Sniffing, and other technologies in our PRTG Detailed System Requirements.

Planning an installation with thousands of sensors?

As a rule of thumb an average PC or server with an average desktop performance should be able to monitor 2,000 sensors with ease (some exceptions apply for SNMP V3, WMI, xFlow, packet sniffing, VMware monitoring and Exchange monitoring). For larger installations please refer to our knowledge base article Planning Large Installations of PRTG Network Monitor.

Important notice: We recommend using a dedicated physical machine that only has the PRTG core server respectively remote probe running on it. If you run PRTG on a virtual machine, we strongly recommend to stay below 2,500 sensors for performance reasons. Unfortunately, we cannot offer technical support regarding performance and stability problems for PRTG installations on virtual machines that run with more than 5,000 sensors. In this case, please migrate PRTG to one or more, preferably physical, machines.


Take a look at our Live Demo


In our live demo you get a first impression of PRTG: how it is used and how the user interface is designed. After seeing how easy and comfortable it is to monitor your network, you can test PRTG your own network here.
