About this task

The impact tree shows the result of impact rules on CI parent and child relationships. The tree represents a business service map with CIs from the Service Configuration Item Association [svc_ci_assoc] table. When related CIs are connected but not part of the business service map, the impact for the related CIs can also appear in the impact tree.

The numbers or percentages on a parent CI summarize overall severity based on alerts from child CIs. The parent severity is based on impact rule computations.

You can also learn about the impact tree from the following video tutorial.

    • Major (orange): Major functionality is severely impaired or performance has significantly degraded.
    • Minor (yellow): Partial, non-critical loss of functionality or performance degradation occurred.
    • Warning (blue): Attention is required, even though the resource is still functional.
