Enriching and correlating events

Correlate events with topology data to enrich events with topology data and to enable root-cause analysis on a set of events.

About event enrichment and correlation
Network Manager uses the Event Gateway to correlate events with topology data and enrich events with a default set of topology fields. Once an event has been enriched, it is passed to plugin processes such as root-cause analysis (RCA) and failover, which take further action based on the data in the enriched event. The enriched event is also passed back to the ObjectServer.
Configuring event enrichment
You can configure the way an event is processed as it passes through the Event Gateway.
Using the OQL service provider to log into the Event Gateway databases
You must log into the databases using the object query language (OQL) service provider and the EventGateway service name to query the gateway databases.
Applying configuration changes to the Event Gateway
Issue the SIGHUP command to the Event Gateway to change the configuration of the Event Gateway.
Configuring common Event Gateway properties
You can configure common Event Gateway properties by editing the NCP_G_EVENT.props file.
Network Manager event categories
The events that are raised by Network Manager fall into two categories: events about the network being monitored and events about Network Manager processes.
Configuring Event Gateway plug-ins
You can configure Event Gateway plug-ins. You can also view currently enabled plug-ins.
Configuring root-cause analysis
You can configure the RCA plug-in.
