The common event infrastructure or CEI is one of the SOA core components that are a part of WPS.
CEI is available to all the supporting services and service components that are running in the process server environment.All of these supporting services and service components have the ability to generate events that can be handled by CEI and then handled by various clients such as those provided by Tivoli® and WebSphere Business Monitor.
The event definition is being standardized through the OASIS standards body so that other companies as well as customers can use the same infrastructure to monitor through-out their environments.
It provides facilities for the runtime environment to persistently store and retrieve events from different programming environments. This post briefly introduces the basic event-related concepts:

- Common Event Infrastructure (CEI)
- Common Base Events (CBE)
Common Event Infrastructure
In WESB, the CEI is used to provide basic event management services, such as event generation, transmission, persistence, and consumption. CEI was developed to address industry-wide problems in exchanging events between incompatible systems, many of which employed different event infrastructures, event formats, and data stores.
Common Base Event
Although CEI provides an infrastructure for event management, it does not define the format of events. This is defined by the Common Base Event specification, which provides a standard XML-based format for business events, system events, and performance information. Application developers and administrators can use the Common Base Event specification for structuring and developing event types.
