PRTG Manual: System Requirements

PRTG consists of two main system parts, the PRTG core server and the probes.

If you want to use PRTG on premises, you need to install PRTG on a system that meets the general system requirements for the PRTG core server (PRTG on premises).
If you want to use PRTG hosted by Paessler, you need to install at least one remote probe on a system that meets the general system requirements for remote probes.

General System Requirements for the PRTG Core Server (PRTG on premises)

For installations of the PRTG core server, you need to meet the following requirements.

Category	Requirement
Hardware	We recommend that you use x64 server hardware or a properly configured virtual environment.
Operating system	We recommend that you use Microsoft Windows Server 2019, Microsoft Windows Server 2016, or Microsoft Windows Server 2012 R2.
Microsoft .NET Framework	Microsoft .NET Framework .NET 4.7.2 or later must be installed on the PRTG core server system or the remote probe system. For new installations of the PRTG core server or remote probes, we recommend .NET Framework 4.8. For more information, see the Knowledge Base: Which .NET version does PRTG require?
Web browser	The following browsers are officially supported by the PRTG web interface (in order of performance and reliability): Google Chrome 72 Mozilla Firefox 65 Microsoft Internet Explorer 11

PRTG hosted by Paessler does not require any hardware for the PRTG core server, but at least one remote probe installation is necessary to monitor your local network when you use PRTG hosted by Paessler.

General System Requirements for Remote Probes

For installations of remote probes, you need to meet the following requirements:

Category	Requirement
Hardware	We recommend that you use compatible x86 hardware or a properly configured virtual environment.
Operating system	We recommend that you use Microsoft Windows Server 2019, Microsoft Windows Server 2016, Microsoft Windows Server 2012 R2, or Microsoft Windows 10.
.NET Framework	Microsoft .NET Framework .NET 4.7.2 or later must be installed on the PRTG core server system or the remote probe system. For new installations of the PRTG core server or remote probes, we recommend .NET Framework 4.8. For more information, see the Knowledge Base: Which .NET version does PRTG require?
Stable network connection	Remote probes require a stable network connection between the PRTG core server and the remote probe. Remote probes that connect to a PRTG hosted by Paessler instance need a reliable internet connection. Unstable connections, for example via 3G, might work but you might lose monitoring data if the connection is unreliable.

Large PRTG Installations

The maximum number of sensors you can monitor with one PRTG on premises installation mainly depends on the monitoring technology and the scanning intervals you use. In general, we recommend that you use a dedicated physical machine to run both the PRTG core server and remote probes. Running large installations of PRTG in a virtual environment is possible if you follow some specific rules and guidelines to achieve the required level of performance.

For more information, see section Detailed System Requirements.

PRTG hosted by Paessler is restricted to a maximum of 5,000 sensors. More sensors are not possible.
