The event catalog contains the specifications for all the events that can be monitored for each service component type, and the associated Common Base Event extended data elements produced by each event.
Use the information presented in this section as reference material that enables you to understand how individual events are structured. This knowledge helps 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.
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, 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 want to include in event.
