PRTG Manual: System Requirements

PRTG consists of two main system parts: PRTG core server and probe.

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

To install a PRTG on premises server and work with it, you need to meet the following requirements.

Category

Requirement

Hardware

A PC or server with at least a dual core CPU and a minimum of 2048 MB RAM is sufficient.

Operating system

We recommend that you use Microsoft Windows Server 2019, Microsoft Windows 10, or Microsoft Windows Server 2012 R2.

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

icon-prtg-on-demandPRTG 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 using PRTG hosted by Paessler.

System Requirements for Remote Probes

Category

Requirement

Hardware

A PC or server with at least a dual core CPU and a minimum of 2048 MB RAM is sufficient.

Operating system

We recommend that you use Microsoft Windows Server 2019, Microsoft Windows 10, or Microsoft Windows Server 2012 R2.

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.

Remote probes can extend your monitoring with PRTG.

  • With remote probes, you can monitor different subnetworks that are separated from your PRTG on premises core server by a firewall, and you can keep an eye on remote locations. You can install one or more remote probes.
  • Remote probes are useful if you want to distribute monitoring load by taking it from the PRTG core server system and putting it on one or more remote probe systems.
  • You need a remote probe if you want to monitor your local network using a PRTG hosted by Paessler instance.

Planning a PRTG Installation with Hundreds of Sensors or More?

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.
