Custom Sensor : Powershell Script



Hello everyone,

I have a script who reads a SQL Lite database from a network share in powershell. It works perfectly directly in PowerShell. But from PRTG, the script can't access to the file. So, after few failures, I try with a mapped network drive. And it's doesn't work neither. Furthermore, when I add " wmic logicaldisk get caption " into the script, and activate the debug into PRTG to write outpu into a file, the script doesn't see the mapped drive. I think the issue comes from the Probe Service, who doesn't use the same account as me.

I also tried to add Windows Systems credentials for the network share into the settings of the object. But it doesn't work neither.

The script is available here : https://github.com/Areku95/SynoBackupSensor

Thank you in advance !

Hi there,

You could check if it works when you change the service account used for the PRTG Probe Service. This can be done via the Service Console of Windows (services.msc). There you open the Properties of the "PRTG Probe Service" and change the "Log On" user to something else. Does it work afterwards?

Best regards.

It works ! Thank you. I just had to modify the import-module with the full path.

Hello folks,

I am facing the same issue. Running a powershelgl script against a remote folder which work fine from a powershell console but not when launch from the prtg console.

I tried to replace the shared folder name by mounting it as a shared drive Z: but no chance there either.

The error message I get is:

+ $files =  Get-ChildItem -Path $path -include $include -Recurse | Sort ...
+           ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : ObjectNotFound: (z:String) [Get-ChildItem], DriveNotFoundException
    + FullyQualifiedErrorId : DriveNotFound,Microsoft.PowerShell.Commands.GetChildItemCommand

I did modify the "Log On" to replace it by a local one user but it hasn't resolved the issue either.

What is strange is that when I run the same script against the local drive of the machine it then works fine.

Any idea in which direction I could continue to follow?
