In a large enterprise environment, servers may change IP addresses, hostnames, cloud instances may be recreated, and the same infrastructure may be discovered from multiple sources.
How should ServiceNow Discovery and IRE determine whether the discovered device is an existing CI or a new CI?
For example:
- What identification attributes should be considered authoritative?
- How should Discovery behave when hostname, IP address, or serial number changes?
- How should duplicate CIs discovered by different sources be prevented?
- When should Reconciliation Rules take precedence over Discovery data?
What approach do you recommend for designing Identification and Reconciliation rules in a large enterprise CMDB?
