Event storage architecture

Edit online

Use this information to understand how the ObjectServer interacts with components of Network Manager.

The following figure shows how data flows through the ObjectServer.

Figure 1. Event storage data flow

Event storage dataflow

1 Events generated by Network Manager polls are sent to the ObjectServer
Probe for Tivoli Netcool/OMNIbus sends the converted event data to the Tivoli Netcool/OMNIbus ObjectServer.
2 Tivoli Netcool/OMNIbus probes and other event sources populate the ObjectServer
Tivoli Netcool/OMNIbus probes and potentially other network event sources, populate the ObjectServer with network events.
3 Event correlation and deduplication
The ObjectServer performs event correlation and deduplication on all the events that it stores.
4 Event enrichment and root cause analysis
The Event Gateway requests a filtered subset of events from the ObjectServer. Enriched events are returned to the ObjectServer. These events are enriched with a default set of topology information. The returned events are also modified with root cause analysis and symptom information.
5 The Tivoli Netcool/OMNIbus Web GUI accesses the event data
Web GUI requests the latest set of events from the ObjectServer. Any changes that the user makes to events using the Web GUI are sent back to the ObjectServer.
