Create a Propagation Policy with Operative Propagation

Operative propagation requires you to specify an impact threshold that causes only impact values greater than or equal to the threshold to propagate to the parent item. Operative propagation policy is useful in situations when a dependent CI is only affected by a child item when the child item's impact becomes severe.

By default, every relationship with operative propagation only propagates impact when the impact of the child CI is equal to or greater than 20. You can change the default operative propagation policy for each relationship that maps to operative propagation. The Service Modeler must be closed to change the default operative policy.

In the Service Modeler, you define operative policies that are specialized for individual relationships.

Follow these steps:

1. Create a new service or modify an existing service.

   The Service Modeler opens.

2. Do one of the following:
   • Select and right-click a relationship that has operative propagation and select Operative Policies, Edit. You can select multiple relationships for the same source CI.

     Note: You must select the relationship so that the relationship line widens for the Edit option to be available when you right-click.

   • Select and right-click a CI that is the source of a relationship that has operative propagation and select Define Policies, Operative Policies, Edit.

   The Operative Policy Editor dialog opens. The table displays whether the policy is new or previously defined, the affected source CI, target CI, relationship, and current threshold.

3. Click Set in the Threshold column, enter an impact threshold between 1-40, and press Enter.

   The threshold changes.

4. (Optional) Do any of the following if necessary:
   • Click Initial to return the Threshold to its initial setting when you opened the dialog.
   • Click Default to return the Threshold to its default setting.
   • Keep the 'When saving, remove default policy equivalents' check box selected to disregard a custom operative policy equivalent to the defined default policy for that relationship and use the default rather than creating the custom policy.

     Note: CIs in maintenance mode are excluded from custom policy calculations related to average or percentage.

   The threshold or setting changes accordingly.

5. Click OK.

   The policy is associated with the specified relationship. Save the service to save any created policies.

Any custom operative policies that you define appear in the Policies tab in the pane below the service topology. You can right-click existing custom policies to edit or delete them. You can edit and delete multiple selected operative policies at the same time.
