Generate report for devices without any sensors

Why would you want to do that? There's nothing to report on ... ;)

Exactly! We have some people that are adding devices into PRTG that aren't on the network yet, and then they neglect to go back and rediscover them after they deploy them. I need a way to see how many we have that are out there in this state (I've found a few so far by accident).

Ah, so you literally need a list of devices that have no sensors configured?

Here you go, save it as Get-EmptyDevices.ps1 and run it on the PRTG server within a PowerShell window:

[string] $ConfigurationFilePath = ((Get-ItemProperty -Path "hklm:SOFTWARE\Wow6432Node\Paessler\PRTG Network Monitor\Server\Core" -Name "Datapath").DataPath) + "PRTG Configuration.dat"
   [xml] $configuration = New-Object -TypeName XML;
         $configuration.Load($ConfigurationFilePath)

$Devices = ($configuration.SelectNodes("//device"))

$DeviceList = foreach ($Device in $Devices) 
{   

    $Sensors = ($configuration.SelectNodes("//device[@id='$($device.id)']/nodes/sensor").Count); 
 
    [pscustomobject]@{
        ObjectID = $Device.id
        Name     = $Device.data.name.Trim();
        Sensors  = $Sensors
        }

}

$DeviceList | Out-GridView

Will look something like this:

Khansen - Great question.

Stephan - Great answer. KB it.

I recently just setup PRTG for a company (number 4 and counting), and added many blank devices to get a better feel of the best structure.

It was only yesterday I manually went through every group looking for blank devices (luck I only have 200 devices so far)

You could adapt this to check all devices of a certain type have certain sensors (eg, all windows servers have CPU and disk sensors). Its not a good feeling to have a monitored server run out of disk space, only to find PRTG was only PINGing it :(

Hi Andrew,

Thanks for the praise, kb'd it ;) You can sure turn this into a compliance checking tool, but that depends on the individual needs - I'd love to do it, but due to us being shortstaffed currently, that's not an option. I might look into it later (and by later I mean next month :D).
