How can I increase memory for Remote PowerShell?



I use several PRTG sensors that use Remote PowerShell. Because I run a large IT environment, the memory that is allocated for Remote PowerShell is not sufficient. This results in errors for Remote PowerShell sensors like The WSMan provider host process did not return a proper response.

How can I turn off the Remote PowerShell memory limitation so that there is always enough memory available for my sensors?

Increasing the memory limit for Remote PowerShell

There are various sensor types for which you have to enable Remote PowerShell to monitor the target devices. By default, a remote shell is allocated a maximum of 150 MB memory. This might be insufficient in larger network environments with, for example, several Hyper-V hosts and dozens of virtual machines.

Remote PowerShell sensors might show the following error message if too little memory is available:

The WSMan provider host process did not return a proper response

In this case, increase the memory limitation of 150 MB to 1 GB. Use the following command to increase the memory allocation limit for Remote PowerShell:

Set-Item WSMan:\localhost\Shell\MaxMemoryPerShellMB 1024

Sensors that use Remote PowerShell will not fail anymore because of the abovementioned memory limit.
