PowerShell script notification

Votes:

0

Hi, I have the following script that checks the windows host file and returns a value based on the lines in the host file. For example, if a host file has an entry in it (that not remarked or 127.0.0.1) it will return an entry number. so if the host file has 1 entry in it the script will out put value 1, and if no entry it will not output any value. The script:

$counter = 0

foreach ($record in Select-String -pattern "^#","^127.0.0.1" -Path C:\Windows\System32\drivers\etc\hosts -NotMatch ) 
{
	if ($record.Line.length -gt 8) 
	{
		$counter = $counter + 1
	}
}
if ($counter -ne 0) {
Write-Host $counter
}

Now, I want to run this script on multiple servers that I monitor and trigger an alert if it returns a value.

Can anyone please help?

Thanks in advance.

Dear Rotem187

To use this script as custom Exe/Script sensor, please expand the output with adding a sensor message. The output format is

value:message

for example

write-host 1:Ok

To alert based on the return value, you can open the sensor's setting tab and add a threshold trigger. As an alternative, you can change the sensor status by using limits for the result channel, and add a state trigger.

There is a third option to change the sensor status: By using an exit code ("errorlevel") of 1 to change the sensor status to waring, or 2, 3, 4 to mark different alarm reasons. Please find the documentation in the PRTG webinterface, menu Setup | PRTG API, tab "Custom Sensors".

Hi, Thanks for the reply. How do i get PRTG to run this script on a remote computer? I created exe/script on a device but it's keeps returning the vales of the PRTG server and not the remote server that the sensor is on.

Thanks

Dear Rotem187

That is correct, scripts are run locally. This prevents a PRTG user to spread possibly harmful scripts to other computers.

You can either expand your script to run a remote powershell, or install a PRTG remote probe on that computer and copy the script into that remote probe (in the same folder as on the core server.) Then create the sensor on the remote probe, and it is run there.
