Flawless Linux network monitoring with PRTG
As a company, you need a central network management. Most important work processes run via the in-house network, which can run via a Windows or Linux server. The job of administrators is to ensure smooth operation and cost-effective utilization. Professional monitoring software such as PRTG can help.
How do I monitor my network traffic on Linux?
PRTG is not only compatible with Windows systems, but also with networks running via Linux servers. With Linux monitoring, you get an overview of the system and device status, as well as updates on traffic strength and potential bottlenecks. You also get important information on users, connections, and your network structure.
Thanks to the built-in Linux server monitoring of PRTG, well-founded decisions can be made on the future development and optimization of your service management. Linux monitoring also lets you monitor the amount of free disk space, allowing you to quickly fix memory errors. Moreover, PRTG features time synchronization monitoring (via NTP).
With PRTG, admins obtain an overview of their Linux networks, employees enjoy a stable working environment, and managers are given figures they can trust. Improve the performance of your network and solve problems before they arise.
Thanks to PRTG, everyone will work with peace of mind.
This is how Linux monitoring with PRTG works
PRTG uses customized Linux and Unix sensors to monitor Linux systems, without the need to install or modify anything on the target device. Linux operating systems are monitored by way of SNMP and SSH protocols, while Linux servers are monitored using WBEM and SSH protocols. With SSH, data is sent via a secure connection to prevent sensitive information from being compromised during the sending of monitoring data.
Customize your own threshold and alarm values. These values are used to inform you if memory surges on one or more servers. Such information is especially important for application and terminal servers which are used by a great many users. Even standard applications such as word processors or spreadsheets can take up so much system memory that overall system performance is impaired. PRTG notifies you before memory bottlenecks occur, enabling your network to perform optimally in the long run.
The PRTG Linux monitoring also lets you monitor the available hard disk space of Linux systems and time synchronization via NTP (Network Time Protocol). PRTG for Linux servers gathers information on system load, RAM, and hard drives directly from the respective systems.
How PRTG defines sensors
In PRTG, “sensors” are the basic monitoring elements. One sensor usually monitors one measured value in your network, e.g. the traffic of a switch port, the CPU load of a server, the free space of a disk drive. On average you need about 5-10 sensors per device or one sensor per switch port.
7 good reasons to choose PRTG as your Linux monitoring tool
Syslog stands for System Logging Protocol and is a standard protocol used to send system log or event messages to a specific server, called a syslog server. It is primarily used to collect various device logs from several different machines in a central location for monitoring and review. The protocol is enabled on most network equipment such as routers, switches, firewalls, and even some printers and scanners. In addition, syslog is available on Unix and Linux based systems and many web servers including Apache.

Linux server monitoring sensors
The following sensors can be used for Linux server monitoring with PRTG:
SNMP Linux
Various sensors that monitor different parameters of a Linux/Unix system using SNMP like:
- Free disk space
- Average system load
- Memory usage
- Input/output on disks
SSH
Several SSH sensors show data like free disk space, load average, memory usage of a Linux/Unix system, status and details of SANs or monitors scripts using SSH.
Python Script Advanced
The Python Script Advanced sensor executes a Python script on the computer and is provided as part of the PRTG API. It can show values returned by the Python script in multiple channels (must be valid JSON or XML).
More data collecting sensors
SNMP Linux Load Average
The SNMP Linux Load Average sensor monitors the "load average” of a Linux/Unix system by way of Secure Shell (SSH) or the Simple Network Management Protocol (SNMP).
SNMP Linux Meminfo
The SNMP Linux Meminfo sensor monitors the memory usage of a Linux/Unix system using Simple Network Management Protocol (SNMP).
Linux Disk Free
The SNMP Linux Disk Free sensor monitors free space on disks of a Linux/Unix system using the Simple Network Management Protocol (SNMP).
The sensor can show the following:
- Free total disk space in bytes
- Free space in bytes for every mounted partition
- Free space in percent for every mounted partition
- Free inodes in percent for every mounted partition
SNMP Traffic
The SNMP Traffic sensor monitors traffic on a device using SNMP. PRTG creates one traffic sensor for each individual port
