How does discovery find the asset tag on a Windows and Linux computer?

[BasantChauhan]

How can I get asset tag data for agent based discovery when not using third party integrations like SG-Intune, SCCM etc.

Is it possible to get asset tag data in agentless discovery? If yes then how?

Where is it stored? An 'asset tag' is just a unique number on the asset. If you have it somewhere stored, you can integrate it to ServiceNow. But with your limited information, it's hard to tell you how.

@BasantChauhan, Asset Tag property is saved with attribute name "SerialNumber". Cloud VM's or Cloud Server's do not have Asset Tags in general (unless assigned a label/tag). If you run the WIM/CIM commands to get the Asset tags, you would get alpha-numeric code like snip below. (You ca run this in your PC to see how it works.)

When you run the similar command on a Physical machine to which an Asset tag is assigned then you would get proper 6 or what ever digits/characters as output.

You can retrieve this through a custom pattern or else run the PowerShell command in the Server where you have installed your Mid-Server agent to fetch the desired property. You can change the filter to get any other attribute as you like.

Let me know if this helped!
