Asset Matching Criteria

The Hardware Reconciliation Engine matches the owned and discovered assets based on the asset matching criteria that you define for a reconciliation rule. The criteria define the matching factors for owned and discovered assets based on a list of field values from both CA APM and the discovery products. The Hardware Reconciliation Engine identifies all assets being managed and provides the required data during the reconciliation process.

If you modify the asset matching criteria associated with a reconciliation rule, the Hardware Reconciliation Engine reprocesses reconciled assets using the new criteria the next time the engine processes the rule.

You can match the following asset field values:

Owned Asset Field

Discovered Asset Field

The product monitors the asset matching fields of owned and discovered assets. If you modify the value of an owned asset field that can be used for asset matching, the Hardware Reconciliation Engine reprocesses the modified owned asset using the new value, during the next reconciliation process.

Similarly, if the discovery component of CA Client Automation or a third-party discovery product modifies the value of a discovered asset field in the CA MDB that can be used for asset matching, the Hardware Reconciliation Engine reprocesses the modified discovered asset using the new value, during the next reconciliation process.

The product also monitors changes to normalization rules for companies and system models. These rules affect the asset matching of owned and discovered assets. If you change one of the normalization rules, the Hardware Reconciliation Engine runs the asset matching process so that assets are matched using the new rules. Any assets that are matched as a result of a previous run of the Hardware Reconciliation Engine are evaluated again to determine if their matching should change based on the new normalization rules.
