Function documentationLegacy: Event-Driven Controls Locate this document in the navigation structure

 

Controls or monitoring rules that respond to messages that external systems send to Process Control are called event-driven controls. Such controls are scheduled and run in Process Control. They execute a query against a back end system to gather data. The external system decides when an event is significant enough to send to the application.

Example Example

The external system could be a network management tool that monitors network traffic, watching for intrusions, system failures, and so on. The process uses a Web service interface that you enable in SAP NetWeaver, to communicate from the external system to Process Control.

End of the example.

Integration

  1. You configure the schema for the event in the Customizing activities for Process Control.

  2. You define a rule to work with that event. These are event-driven rules. The name of the rule must be exactly the same as the name of the event.

  3. Based on the number of events, you specify the criteria that the rules use to create issues.

  4. Associate your event-driven rule with a control. This combination is an event listener. It is ready to receive and process events as defined.

  5. Decide if the event listener is active or inactive. You set this parameter on the Event Monitoring Activation screen.

When Process Control judges a received event to be significant, the system creates an issue, and a workflow message to notify the appropriate user that an issue has been created.

Note Note

  • The external system notifies Process Control when the defined event occurs. Job scheduler does not schedule event-driven controls.

  • Process Control uses the Event Monitor to track and monitor events. For more information, see Event-Based Control Monitoring
