For which sensor types do you recommend at least Windows Server 2012 R2 and why?

Votes:

0

In the system requirements for PRTG, you recommend at least Windows Server 2012 R2 on the probe system for best performance of some sensor types. For which sensor types does this recommendation apply? Why is it better to use at least Windows Server 2012 R2 for these sensors instead of other operating systems?

Important Information: This article is deprecated and is no longer updated. As of October 2023, PRTG no longer supports Windows Server 2012 R2. We recommend you use the most recent version of Windows Server.

This article applies as of PRTG 22

Recommended operating system: Windows Server 2012 R2 or later

As you can see in the supported operating systems of the system requirements for PRTG, we recommend that you use at least Windows Server 2012 R2 on the probe system (either local or remote probe). Windows Server 2012 R2 provides the best performance for various sensor types.

This recommendation especially holds for all sensors that execute HTTP web requests via a script. We found out that the performance of these sensors is better by a factor around 10 as of Windows Server 2012 R2 compared to Windows Server 2008 R2.

For example, this affects all VMware sensors using the Simple Object Access Protocol (SOAP): the VMware Datastore (SOAP) sensor, the VMware Host Hardware Status (SOAP) sensor, the VMware Host Performance (SOAP) sensor, and the VMware Virtual Machine (SOAP) sensor.

You can monitor

  • up to 300 VMware sensors with a 60-second scanning interval if your PRTG core server (or remote probe) runs on at least Windows Server 2012 R2,
  • but only 30 VMware sensors with a 60-second scanning interval if your PRTG core server (or remote probe) runs on Windows Server 2008 R2.

For details about the performance of VMware sensors, see How can I increase the connection limit on VMware systems? PE121.

Other sensors that show an increase in performance by a factor of 10 are, for example,

Also keep this performance improvement in mind when creating your own custom sensors, for example, an EXE/Script sensor, and when your custom script performs such a request.

If possible, set up the PRTG core server and/or remote probes on at least Windows Server 2012 R2 if you frequently use the mentioned sensors.
