Correlation rules and related events
A correlation rule is a mechanism that enables automatic action on real-time events that are received by the ObjectServer, if a trigger condition is met. The result is fewer events in the Event Viewer for the operator to troubleshoot. You can view the correlation rule for a related events group in the Correlation Rule tab of the Related Event Details portlet.
Writing a correlation rule in code is complex but the related events
function removes the need for administrators to code a correlation
rule. Instead, the related events function derives a correlation rule
from your related events configuration and deploys a correlation rule,
all through the GUI. After the correlation rule is deployed in a live
environment and if the trigger condition is met, then automatic action
occurs.
- The trigger condition is the occurrence of one or more related event types, from an event group, on the Tivoli® Netcool®/OMNIbus ObjectServer. Only one event must be the parent event. Related event types are derived from your related events configuration.
- The automatic action is the automatic creation of a synthetic event with some of the properties of the parent event, and the automatic grouping of the event group events under this synthetic event.
