Using relationships in Event Viewers

If relationships between events are defined, you can organize the event list in an Event Viewer that is based on those relationships. Use views to apply the relationships to the Event Viewer.

When relationships are applied, the event area of a list has a tree-like appearance, with events shown in a hierarchical fashion. At the top level are the main events that are determined by the relationship. For example, if the relationship is root cause and symptom, this top level contains all the root cause events. Events beneath those top-level events are the subsidiary ones. Continuing the root cause example, these subsidiary events are the symptoms, with one or more associated with each root cause.

Before you begin

  1. Define the event relationship and add it to a view, or create a view for the relationship.
  2. Add the view to the Event Viewer by editing the widget preferences.

Procedure

  • If an Event Viewer is organized by relationships, a plus sign (+) next to each top-level event indicates that it has subsidiary events. Click the plus sign to reveal the subsidiary events; the plus sign changes to a minus sign (–). To close the list of subsidiary events, click the minus sign.
  • You can use all other functions of the Event Viewer, such as viewing event details, in the normal way.
