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.
