My probe (and so my ps1 Altoro monitor script) is running on another machine then the server i want to monitor. The result is that a add a line to the original script: Invoke-Command -ComputerName $host [hyper-v] Where hyper-v is the machine that needs to be monitored. The remote powershell execution is working on this machine.

The output gives 1 error i can't tackle. The error is:

PS C:\Program Files (x86)\PRTG Network Monitor\Custom Sensors\EXE> C:\Program Files (x86)\PRTG Network Monitor\Custom Sensors\EXE\Altaro-monitor.ps1

Good Morning,

could you help me with this custom sensor please? After follow your guide, the result is:

0:Specified BackupType not local or offsite, quitting

Thanks in advance, regards.

What result do you get when you run it manually?

Hello,

same result as PRTG sensor: 0:Specified BackupType not local or offsite, quitting

It's needed to replace something in script?

Thanks.

Then you're likely not passing the correct parameters here. Did you enter the VM name in the Script at the very beginning? It's *null* by default, so it may error if you don't pass them correctly.

Yes, that's how it's supposed to look. Just to make sure, does the script perhaps need to run on the actual backup server (i.e. on a remote probe on the backup server)?

Hello, yes, I'm running script on Backupserver device on PRTG. But fails on powershell too. Should be I'm writting wrong shometing... I tried with many different combinations but always fails. Do you have an example for check it with names instead variables please? Thanks in advance.

When you filter the given event log for the name of the configured virtual machine, do you get any results?

Hello,

I can't run successfully this script... is working correctly for you?

Thanks in advance, regards.

What error do you get when you run it manually with the same parameters? Did you follow our Guide for PowerShell based custom Sensors for the installation?
