View the impact tree

The impact tree shows the relationships between CIs and the relative percentage impact for each child CI. This information is available for both discovered services and manual services.

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 Associations [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.

Figure 1. Impact Tree


  1. Open the business service map for the service from either the Event Management dashboard or the Manual Services list.
    From the Event Management dashboard

    2. Double-click the tile of the service.
    From the Manual Services list
    1. Navigate to Event Management > Services > Manual Services.
    2. Click View Map next to the service.
  2. On the business service map, click a CI that has a severity color.
  3. Click the Impact tab.
  4. From the Impact Tree tab in the side pane, expand the parent CI and click the CI that generated alerts.
  5. Use the severity color to locate CIs that contain alerts:
    • Critical (red): Immediate action is required. The resource is either not functional or critical problems are imminent.
    • Major (orange): Major functionality is severely impaired or performance has 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.
    • Info (green): An alert is created. The resource is still functional.
  6. Do one or more of the following:
    Adjust impact rules
    1. Click the Impact tab.
    2. Review and adjust the impact rules as necessary.
    Remediate an alert
    1. Click the Alerts.
    2. Right-click the alert and select Run remediation.
