PRTG makes maintaining your Linux network's health easy

Custom alerts and data visualizations make it easy to monitor, identify, and prevent Linux server and network performance issues














Introducing: fuss-free Linux network monitoring

Running a Linux/Unix network?

Now, you can keep an eye on key metrics like trafficbandwidthsystem and device status, and time synchronization via NTP, optimize performance, and troubleshoot issues without having to install or modify anything on your monitored devices themselves.

Simple to set up and use, but extremely powerful and highly customizable, our Linux network monitoring tool Paessler PRTG uses SNMP and SSH protocols, as well as custom scripts to securely send data to your PRTG servers, where you can keep track of your network's health and get alerted as soon as something's about to go wrong.


What Linux network monitoring looks like in PRTG

Diagnose network issues by continuously monitoring your Linux operating system. Show server capacity, bandwidth, free memory, and other network health stats in real time and visualize data in graphic maps & dashboards to identify problems more easily. Gain the visibility you need to troubleshoot bottlenecks and maximize performance.

The sensible choice: 4 reasons to use PRTG as your Linux monitoring tool

Super simple setup

So easy you could do it in your sleep. The setup assistant will walk you through the process and the automatic network discovery detects Linux devices and more in your network. Once you're up and running, you can customize the monitoring environment to suit your requirements.


Real-time alerts

Pick your preferred Linux server performance thresholds and get notified the second your Linux network’s at risk of going under or exceeding them, so you can fix issues before they cause disruptions (and leave the office at a reasonable hour).


Complete visibility

When security threats arise, you need to know at once, whether you’re in the office, at home, or on vacation. PRTG server security continuously monitors your servers and hosts, alerting you even before there is a critical issue. Our PRTG apps for iOS and Android give you the freedom to leave the server room with peace of mind, knowing that if there is no alert, everything’s running smoothly.


Better results

Secure your Linux network and optimize performance, while reducing your workload. Need we say more? With PRTG working in the background 24/7,  you'll save time, be proactive, and have the peace of mind that nothing will fall through the cracks.

Linux network monitoring: FAQ


1. What is PRTG Linux network monitoring?

PRTG is a proprietary software tool that also monitors Linux network performance and hardware health. The solution is Windows-based, but the used technology enables you to configure a Linux monitoring environment, so you can track your Linux network's stats and spot potential issues from one user-friendly location.

2. Can I install a PRTG core server or probe on Linux?

No. You can only do it on Windows. But, once you've installed the PRTG server, you can download the included, free PRTG app for desktop that also runs on Linux. With this app, you can monitor and manage your complete IT infrastructure from your Linux system. Alternatively, try our fully Linux-compatible hosted monitoring solution PRTG Hosted Monitor.

3. Do you plan on developing an edition of PRTG Network Monitor that is compatible with Linux?

Yes and no. We do not plan to develop a complete PRTG Network Monitor edition for Linux. However, we’ll release our brand-new Multi-Platform Probe in February 2024, which runs on all your Linux and Unix systems and offers the full PRTG feature set.

4. How much does PRTG Linux network monitoring cost?

We're so confident you'll love PRTG that it comes with a free, no-obligation 30-day trial. Should you decide to keep using it, you can choose from:

  • A perpetual, on-premises PRTG Network Monitor license – ideal for small to medium-sized organizations
  • A cloud-based PRTG Hosted Monitor subscription
  • An on-premises, subscription-based PRTG Enterprise Monitor license that supports unlimited devices – ideal for large enterprises

5. What is a sensor in PRTG?

In PRTG, “sensors” are the basic monitoring elements. One sensor usually monitors one measured value in your network, for example the traffic of a switch port, the CPU load of a server, or the free space on a disk drive.

On average, you need about 5-10 sensors per device or one sensor per switch port.
