About scope-based grouping events

To achieve further event and ticket reduction, use IBM Netcool Operations Insight Event Analytics on top of the Tivoli Netcool/OMNIbus scope-based event grouping function to create super groups.

The scope-based event grouping function groups events that come from the same place around the same time as it's most likely that these events relate to the same root problem. The same place might be a geographic cell site ID or a common node logical grouping. For more information about the Tivoli Netcool/OMNIbus scope-based event grouping function, see Enabling scope-based event grouping.

The Event Analytics related events grouping function, looks at the event history and determines which events historically occur together. Event Analytics uses these insights to group related events together for when the event types occur in the future.

Netcool Operations Insight can use both the Event Analytics related events mechanism and the scope-based event grouping mechanism to create super groups. The scope-base event grouping automation code base is extended in Tivoli Netcool/OMNIbus v8.1.0.17 to support these super groups.

The term super groups describe where groups of events are themselves grouped together under a single higher-level synthetic parent event. After an Event Analytics grouping has been deployed, then Netcool Operations Insight automatically groups together the relevant scope-based event grouping synthetic parents under a top-level synthetic parent event for when the event types occur again in the future.

The two grouping mechanisms use the ParentIdentifier field to link parent events to child events. However, the two mechanisms do no clash after you complete the configuration steps for Configuring Event Analytics to use scope-based grouping. After this configuration is complete, the ParentIdentifier field for the scope-based event grouping synthetic parent event is created with a blank ParentIdentifier field. Therefore, the Event Analytics mechanism sets the ParentIdentifier field value and links the synthetic parent event to a higher-level synthetic parent event.
