On CI identifiers, I see that a new identifier entry is introduced. What is the use of it ? when do we use it?

Hi @Suggy ,

Use of product_instance_id in IRE rule

  • It’s an extra unique key used by IRE (Identification and Reconciliation Engine) to identify a CI.

  • Normal identifiers (like serial number, hostname) sometimes aren’t enough.

  • product_instance_id helps when a device has multiple instances of the same product (e.g., multiple Oracle DBs on one server).

Why introduced?

  • To avoid duplicate CIs in CMDB.

  • Makes sure each product instance is matched correctly during discovery/integration.

When do we use it?

  • When Discovery or integrations (like SCCM, cloud, Service Mapping) provide a unique instance ID.

  • Especially for databases, middleware, clustered apps, or multiple software installs on one machine.

 

In short: product_instance_id ensures each product instance on a CI is uniquely identified and prevents duplicates in CMDB.


Thanks & Regards,
