To install and work with PRTG Network Monitor you need:

  • A PC or server with average desktop performance or better 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 10 or 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.
