Hi @AhmerFaraz0001 

Step by step instruction is given in this post :

https://www.servicenow.com/community/itom-forum/cmdb-health-dashboard-and-discovery-include-only-pri...

• Go to CI Class Manager → Configuration Items → Health → Inclusion Rules.
• Create a new rule for cmdb_ci with the required metrics, then save it.
  • Right-click on Inclusion Condition and choose Configure Dictionary.
  • In the Attributes field, enter condition_builder= v2 without quotes) and save.
  • Return to the inclusion rule you just created.
• For each rule, do the following:
  • Double-click Inclusion Condition to open SN Utils.
  • Replace the existing value with:       

                           sys_class_nameINjavascript:new PrincipalClass().getPrincipalClasses()

• SN Utils is helpful here because it allows you to leave the condition operator empty.

• • Add any additional conditions (such as install status exclusions) based on your requirements.

The step‑by‑step instructions make this configuration very straightforward to implement. Using

sys_class_nameINjavascript:new PrincipalClass().getPrincipalClasses()

is a clean and effective approach, and the additional guidance around enabling condition_builder=v2 and using SN Utils removes a lot of ambiguity.

Really appreciate you taking the time to document this so clearly—this will be very helpful for anyone looking to restrict CMDB Health to Principal Classes while staying aligned with best practices.
