IRE — Identification & Reconciliation Engine

Definitive questions

• +What problem does IRE solve?
• +What is an identification rule?
• +What is a reconciliation rule?
• +What is dependent identification?

Scenario drills

1. Integration silently drops updates

   “A REST-based CMDB feed reports it succeeded but the CI 'environment' field never changes. What's happening?”

   Approach

   • IRE has a reconciliation rule granting a different data source ownership of that attribute.
   • The integration write is accepted, then IRE drops the field per the ownership rule.
   • Fix by either changing the data source name on the integration or updating the reconciliation rule precedence.

   // Inspect via cmdbTransformAPI response
   { result: { status: 'SUCCESS', items: [{ attributes: { environment: 'IGNORED' } }] } }

   Alternate approach

   Alternate: call the identifyCI script include directly with a test payload in a background script to see exactly which rule dropped the field.

   Pitfall

   Assuming HTTP 200 means the field wrote. Always inspect the IRE response payload.
