About this task

In the map view of a manual or of a discovered service, you can see that the severity of a child service is propagated to the parent service.

A business service is affected by the severity of alerts that are directly associated with it and alerts on the CIs that are in the service. If the severity of a child service is higher than that of its parent service, on the map view the parent service shows the severity of the child service. In the map view, the Impact Tree list shows the CIs. The color of the CIs indicates the alert severity. The child service is also affected by business services that are under it.

Child service severity is propagated to parent service.

If a loop is created, for example, by connecting a parent service to a sub-service, this relationship can be viewed in the map view. The impact of this loop is not calculated and the Impact Tree does not display this relationship. For example, assume that there are three CIs, A, B, and C, where C is a sub-service to B and B is a sub-service to A. The relationship of the A connected service to C is displayed in the map view. However, this relationship is not shown in the Impact Tree.

Click a service or CI to see the alerts that are associated with it. For example, if you click the high-level business service, the alerts that are associated with it are displayed in the alert area under the Map View. The alerts listed are those of the selected service. Alerts of child-services are listed when those services are selected.
