Hi there,

Has anyone had success with retrieving monitor serial numbers remotely and have them add to inventory?

if so, how did you do it?

Many thanks

I modified the script from robvanderwoude.com I mentioned above to output a textfile to C:\Windows\Temp\KACE-Monitor-info.txt. I also made a custom inventory rule to return the fileinfo of that file.

It shows up in the custom inventory, but double spaced. So the only improvements it could use would be to come up single spaced, and also for some reason on my home PC, it shows 2 monitors (with same SN).

Here is the modified script.

  • this is awesome... how can I get this txt file info into a custom inventory rule?
  • I created a custom inventory field:

    Display Name (title): Monitor Serial Number
    Publisher (Vendor): My Company (replace this with yours)

    Supported OS: Windows - I picked all Windows I saw, except Windows 2000. Because I have very few of those left < 1%. If you need Win2k support, the script would need to be modified and also the custom inventory rule.

    Custom Inventory Rule:
    FileExists(C:\Windows\Temp\KACE-Monitor-info.txt) AND ShellCommandTextReturn(cmd /c type C:\Windows\Temp\KACE-Monitor-info.txt)

    For the script I put it as an offline kscript.
    • I agree this is awesome... but we've only had our kbox for a few months and i havent learned to do scripts before today (the auditor is here for a month :( uggg) Is there a comprehensive import vbs scripts to kace script somewhere?

      I am able to run the above script from a pc (not from kace console) and get the resulting text file to show in kace custom inventory field.

      I just cant figure out how to combine the above script with the:

      "The following is an example of the XML structure for an appliance script:
      <?xml version="1.0" encoding="utf-8" ?>
      <kbots xmlns="http://kace.com/Kbots.xsd">
      <kbot>
      <config name="name="" type="policy" id="0" version="version="" description="description="">

      <execute disconnected="false" logged_off="false">
      </execute>

      </config>
      <compliance>
      </compliance>
      </kbot>
      </kbots>"

      requirement from the Creating and editing scripts help section. How can do?
  • After seeing the script in action I see some potential drawbacks:

    The monitor sn will not be unique in the custom inventory fields, because if a computer monitor was not uninstalled on a PC before removal, it will still show up in the registry.

    Also, the monitor may show up on a lot of computers registry if it was on the master sysprep image.

    I plan to test out Extron EDID manager to see if it reads from the monitor EDID instead of the windows registry.

Here is a vbscript that will get that info. 

Capture the output to a txt file and use in a custom inventory rule

 

  Set wshShell = WScript.CreateObject( "WScript.Shell" )
 strComputerName = wshShell.ExpandEnvironmentStrings( "%COMPUTERNAME%" ) 
 WScript.Echo "Computer Name: " & strComputerName 
 Set objWMIService = GetObject("winmgmts:\\" & strComputerName & "\root\CIMV2") 
Set colItems = objWMIService.ExecQuery( _ "SELECT * FROM Win32_ComputerSystemProduct",,48) theValue = "" For Each objItem in colItems theValue = objItem.IdentifyingNumber Next 
 getPCSerialNumber = theValue WScript.Echo "Serial Number: " & theValue

  • Probably the best solution would be Monitor Asset Manager from EnTech Taiwan. It reads the EDID directly from the monitor. But it also costs $1 per user according to http://www.entechtaiwan.com/util/moninfo.shtm

    Some alternatives that may work are DumpEDID from www.nirsoft.net/utils/dump_edid.html, or this script from http://www.robvanderwoude.com/files/dispedid_vbs.txt.

    These will read from the registry, which may not be entirely accurate. The reg entries are under HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\DISPLAY.

    For instance, DumpEDID returns 2 results even though I have 1 monitor. The results for the monitor model and sn are the same, but the registry keys are slightly different. I believe this is because I updated the driver for my monitor instead of uninstalling it.

    The script will probably be better because you can easily modify it to write to a text file and then read that file with a Custom Inventory rule. But I haven't tried the script on a dual monitor setup so I don't know if it works completely.

    All this info for Windows only.
