IRE Factory

Two sources push conflicting data for the same CI. Configure identification rules, set reconciliation priorities, and watch who wins.

Identification Rules

Serial Number Match

match: serial_number · priority: 1

Name + IP Match

match: name + ip_address · priority: 2

Name Only Match

match: name · priority: 3

Reconciliation Rules

For each attribute, list the data sources authorized to update it, in precedence order. Any source not in the list is blocked. Empty list = no rule (any source may write, last-writer-wins).

Real ServiceNow IRE concepts — cmdb_identification_rule, cmdb_reconciliation_rule. Each reconciliation rule names the data sources authorized to update a set of attributes on a CI class; non-authorized sources are blocked. This sim is a learning tool, not a replacement for the platform.
