How can I monitor systems running LINUX and UNIX with PRTG?



I have a PRTG Unlimited license.

How do I configure PRTG for LINUX and UNIX? I managed to add a device for a Linux system in my PRTG web interface successfully. But now I need help how to monitor CPU and memory usage.

Please let me know.

This artcile applies to PRTG Network Monitor 12 or later, as well as to previous (deprecated) versions

Monitoring a Linux/Unix Machine With PRTG

Steps to do:

  1. On your Linux/Unix machine, please install SNMP daemon.
  2. In PRTG, add a "device" for your Linux/Unix machine and
  3. create an SNMP Library sensor on it (select Basic linux library from the drop-down).

For detailed instructions, please refer to this article.

Please see also How do I monitor system parameters like memory, CPU and disks on Linux systems via SNMP? for more information.

Native Sensors

PRTG also includes several SSH sensor, allowing monitoring Linux systems via SSH. For more details, please see the user manual at List of Available Sensor Types: Linux/Unix/OS X Sensors.

Dear I have several hp-ux(11.23) system. i made a script for CPU Sensor on HP-UX. the script was worked very well with PRTG. just two machines has been encountered an errror as like : "No valid result from SSH Shell" So, i tried to set for the sensor : Write result to disk (Filename: "Result of Sensor [ID].txt") By the way, it is not in there. How can i do it?

normally this error-message indicates that the shell-timeout for the sensor is set too low. Please try to increase the shell-timeout in the sensor setting.

Kind regards...
