Custom alerts and data visualization let you quickly identify and prevent Linux server and network performance issues.
Running a Linux/Unix network?
Now, you can keep an eye on key metrics like network traffic, bandwidth usage, system 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.
PRTG now lets you monitor the health and performance of your Linux system – from your Linux system. How? With our multi-platform probe, the new PRTG remote probe for non-Windows environments (Ubuntu, Debian, CentOS, ARM, and many others). Find out more
Diagnose network issues by continuously tracking your Linux operating system and network devices. Show server capacity, network bandwidth, free memory, and other performance monitoring metrics in real time. Visualize monitoring data in clear graphs and dashboards to identify problems more easily. Gain the overview you need to troubleshoot bottlenecks and maximize performance.

So easy you could do it in your sleep. The setup assistant will walk you through the process in the graphical web interface, and the auto-discovery detects Linux devices by IP address or DNS name in your LAN. Once you're up and running, you can customize the monitoring environment to suit your requirements.
Pick your preferred Linux server performance thresholds and get notified the second your Linux network usage is 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).
A thorough view of your Linux network, at your fingertips. Whether you need to check real-time server capacity, free hard disk space, RAM, or other key network health stats, PRTG's customizable maps and dashboards make the process quick and easy.
Secure and optimize your Linux network with bandwidth monitoring, 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.
PRTG comes with more than 250 native sensor types for monitoring your entire on-premises, cloud, and hybrid cloud environment out of the box. Check out some examples below!
The SNMP Linux Meminfo sensor monitors the memory usage of a Linux/Unix system. It can show the following:
The SNMP Linux Load Average sensor monitors the system load average of a Linux/Unix system. It can show the following:
The SSH Disk Free sensor monitors the free space on disks of a Linux/Unix system using Secure Shell (SSH). It can show the following:
The SSH Script Advanced sensor connects to a Linux/Unix system via Secure Shell (SSH) and executes a script file that is located on the target system. This option is available as part of the PRTG API. It can show the following:
See the PRTG Manual for a list of all available sensor types.
Real-time notifications mean faster troubleshooting so that you can act before more serious issues occur.
Set up PRTG in minutes and use it on almost any mobile device.
“Excellent tool for detailed monitoring. Alarms and notifications work greatly. Equipment addition is straight forward and server initial setup is very easy. ...feel safe to purchase it if you intend to monitor a large networking landscape.”

Linux monitoring involves the continuous observation and analysis of system performance, resource utilization, and application behavior on Linux-based operating systems. It includes tracking various metrics such as CPU usage, memory usage, disk I/O, and network activity to ensure optimal system operation.
Linux monitoring tools like Paessler PRTG provide real-time insights into system health, identify potential issues or bottlenecks, and enable proactive maintenance and troubleshooting.
Yes and no. If you use PRTG Network Monitor or PRTG Enterprise Monitor, the central PRTG server can only be installed on a Windows server. But, once you've installed the PRTG server, you can use the brand-new multi-platform probe that also runs on Linux. With this probe, you can monitor and manage your complete IT infrastructure from your Linux system. If you use PRTG Hosted Monitor, you do not need a dedicated Windows server at all.
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:
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.
Paessler conducted trials in over 600 IT departments worldwide to tune its network monitoring software closer to the needs of sysadmins. The result of the survey: over 95% of the participants would recommend PRTG – or already have.
Paessler PRTG is used by companies of all sizes. Sysadmins love PRTG because it makes their job a whole lot easier.
Bandwidth, servers, virtual environments, websites, VoIP services – PRTG keeps an eye on your entire network.
