In order to install and work with PRTG Network Monitor you need:

  • A PC, server or virtual machine with roughly the CPU performance of an average PC built in the year 2007 or better and minimum 1024 MB RAM memory
  • Microsoft® Windows 7 or later (server or workstation, 32 or 64 bit)
  • Web browser Google Chrome 38 or later (recommended), Firefox 33 or later, or Internet Explorer 10 or 11 to access the web interface

More information as well as detailed requirements for monitoring with SNMP, WMI, NetFlow, and Packet Sniffing can be found in our PRTG Detailed System Requirements.

Planning an installation with thousands of sensors?

As a rule of thumb an average PC/server built in the year 2007 or later should be able to monitor 1,000 sensors with ease (some exceptions for SNMP V3, WMI, packet sniffing, and VMware apply). 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 to run both the PRTG core server and PRTG remote probes. If you run PRTG on a virtual machine, we strongly recommend to stay below 2,000 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.
