Event catalog

The event catalog contains the specifications for all the events that can be monitored for each service component type, as well as the associated Common Base Event extended data elements produced by each event. You should use the information presented in this section as reference material that will enable you understand how individual events are structured. This knowledge will help you decipher the information contained in each event, so that you can quickly identify the pieces of information you need from the relatively large amount of data generated by each event. The information included in this section covers the structure and standard elements of the Common Base Event; the list of events for the Business Process Choreographer service components and WebSphere Process Server-specific service components; and, the extensions to the Common Base Event unique to each event type. There is also a discussion of how business objects that may be processed by a service component are captured by in Common Base Events.

When an event of a given type is fired across the Common Event Infrastructure (CEI) bus to the CEI server or to a logger, it takes the form of a Common Base Event — which is, essentially, an XML encapsulation of the event elements created according to the event catalog specification. The Common Base Event includes a set of standard elements, process server component identification elements, Event Correlation Sphere identifiers, and additional elements unique to each event type. All of these elements are passed to the CEI server or logger whenever an event is fired by a service component monitor, with one exception: if the event includes the business object code within the payload, you may specify the amount of business object data that you wish to include in event.
