PRTG Manual: System Requirements
PRTG Network Monitor consists of two main system parts: the PRTG core server and one or more probes.
For details, see section Architecture and User Interfaces.
- If you want to use PRTG on premises, you need to install the PRTG server on a computer that meets the System Requirements for 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 computer that meets the System Requirements for PRTG Remote Probes.
System Requirements for PRTG Core Server (PRTG on Premises)
To install a PRTG on premises server and work with it, you need to meet the following requirements.
System Requirements for PRTG Core Server |
|
|---|---|
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):
|
PRTG hosted by Paessler does not require any hardware for the PRTG server, but at least one remote probe installation is necessary to monitor your local network when using PRTG hosted by Paessler.
System Requirements for PRTG Remote Probes
System Requirements for PRTG Remote probes |
|
|---|---|
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 server and the remote probe. Remote probes that connect to a PRTG hosted by Paessler server 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 are helpful for monitoring with PRTG because they can extend your monitoring.
- 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 system running the PRTG core server and putting it on one or more systems running a remote probe.
- You need a remote probe if you want to monitor your local network using a PRTG hosted by Paessler instance.
Planning a PRTG on Premises 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 PRTG remote probes.
For more information, see section Detailed System Requirements.
PRTG hosted by Paessler is restricted to max. 5,000 sensors, more sensors are not possible.
