You uploaded to an empty CMDB. How to you reconcile/update with existing entries as not to duplicate? Is there a sandbox test scenario showing the anticipated changes without upload?
Hi @tmassing.
You brought up an excellent point! While Mike’s demo started with no devices in the ServiceNow CMDB, the challenge lies not only in populating the CMDB with all the devices in the IT estate but also in avoiding duplicates, especially when using more than one discovery source. To address these issues, ServiceNow has implemented the Identification and Reconciliation engine (IRE).
From ServiceNow Documentation: “The Identification and Reconciliation Engine (IRE) in ServiceNow is a critical component of the Configuration Management Database (CMDB) that ensures data integrity by accurately identifying and reconciling Configuration Items (CIs) from various data sources. This process prevents duplication and maintains a consistent, reliable CMDB.”
The Forward integration relies on ServiceNow IRE, so you never have to worry about duplicates.
Forward provides detailed documentation on how to:
• Add read-only access to the required ServiceNow tables,
• Create a new Discovery Source, and
• Configure the IRE.
