Troubleshooting circular relationship in service models

Supported with 11.3.02 and later

Special type of event to indicate the presence of circular relationship in service models is supported only with TrueSight Infrastructure Management version 11.3.02 and later.


If a service model has a circular relationship, the impact status is not computed accurately. The cell creates a special event to indicate the presence of such a circular relationship in a service model as shown in the following image:

Consider the following service model, the Business Service is getting impacted by ComputerSystemCI_1 and ComputerSystemCI_2. The ComputerSystemCI_2 is getting impacted by ComputerSystemCI_1, and ComputerSystemCI_1 in turn is getting impacted by ComputerSystemCI_2 forming a circular relationship.

You can remove the circular relationship using the BMC Impact Model Designer as explained in the following section:

Important information about deleting a CI association

The circular relationship event that is displayed in the TrueSight console will display the details about the latest CI relationship that caused the circular relationship in the service model. You can remove any CI relationship as per your requirement, even though the event is created for the latest CI relationship that caused the circular relationship in the service model.
