Theory of Operation regarding Product Model creations

Hi HAM forum members.

Perhaps I am not in the correct forum and when this is the case: guide me towards the correct one!

Probably anyone of you can help me (and others) regarding topics around Hardware Product Models and how they are used. As these Product Models are mandatory for every Asset and every CI and they determine the Asset Model Category and with that the Asset Class and CI Class they are important.

Questions I have are:

  • Are Product Models used in import sets? Is there a check that prevents Assets or CI's to be imported into the wrong tables that are tables not specified in the imported Product Model?
  • Are and if so How are Product Models used by ServiceNow discovery?
  • Are and if so How are Product Models used by Service Graph connectors?

I know that for Software discovery/integrations a Discovered Model table is available that is able to create the mapping towards the Software Model table. Is there something similar for Hardware?

I have seen that in many cases new Product Models are created, sometimes even a new PM for each CI/Asset that has been discovered what can impossible be the good practice.

 

When somebody can explain and/or guide me to the explainery info: Many thanks.

 

Looking forward,

 

Ed

Hi Ajay,

 

Sorry for my late reaction and thanks for your links towards the several docs. These docs give at least an explanation on Product Model basics. Unfortunately they do not give insights/ do not go in-deep/ do not give answers to the questions I have: 

  • Are Product Models used in import sets? Is there a check that prevents Assets or CI's to be imported into the wrong tables that are tables not specified in the imported Product Model?
  • Are and if so How are Product Models used by ServiceNow discovery?
  • Are and if so How are Product Models used by Service Graph connectors?

We want to go for a high quality CMDB and where applicable AMDB. Product Models are the basic for every CI and every Asset so depending on settings in Product Model checks should be done to guarantee this high quality data target. So due to this I am investigating in the different ways to create and update CMDB and AMDB data and how this is done from technical perspective.

When  you can guide me towards any docs that probably give answers to my questions I will be very helpfull.

 

Cheers,

 

Ed
