In BMC Impact Model Designer, for each CI, you select one of the predefined status computation models: Standard, Cluster, Weighted Cluster, and Self-Preferred. Standard is the default status computation model.

Description of predefined status computation models

Status computation model

Description

Standard

Computes the status of a component by using the HIGHEST_VAL impact_function; the impact_status is the highest propagated_status of the incoming relationships.

Standard Unknown

Identical to the Standard model except that no_alert_status is set to UNKNOWN instead of OK

Cluster

Computes the status of a component by using the QUORUM impact function (See Quorum algorithm examples.)

Weighted Cluster

Computes the status of a component by using the Status Weight attribute of the impact relationship object Status Weight is used in impact relationships to determine how much importance (numerically weighted) to give to each provider relationship that impacts a consumer instance. The higher the number, the greater the importance.

Self-Preferred

Computes the status of a component by using the self-preferred algorithm for the consolidation_function

The BMC_STATUS_COMPUTATION data class is the basis of all status computation model instances.
