I’m looking for guidance on CMDB data segregation and standardization.
We currently have multiple customers’ data stored within a single CMDB, spanning 91 CI classes. I’m trying to determine the most effective way to segregate the data while maintaining a common attribute that can be consistently applied across all classes for de-duplication task.
Additionally, the current Discovery setup is only populating very limited attributes for most CIs, and many important data points are not being discovered.
I would appreciate insights on:
Recommended approach to segregate multi-customer data within one CMDB
Best practice for introducing a common attribute across all CI classes
How to improve Discovery coverage when patterns are returning minimal information
Any CSDM-aligned guidance for multi-tenant CMDB design

Hi @nehajha
Segregate multi-customer data in CMDB (Assuming your instance is domain separated):
introducing a common attribute across all CI classes :
Introducing a common attribute across all Configuration Item (CI) classes in Servicenow is best achieved by adding the new field to the Configuration Item [cmdb_ci] table. Because all specific CI classes (e.g., cmdb_ci_server, cmdb_ci_netgear) inherit from this root table, the new attribute will automatically cascade down to all classes.
improve Discovery coverage when patterns are returning minimal information:

Hey @nehajha - Yansa Labs maintains a great, lightweight data segregation app for situations where data separation is needed, but full-fledged domain separation is overkill. Many customers use it for similar use-cases to your own. You can check the links below for more information - feel free to reach out if you want to learn more!
