APPARATUS, METHODS AND COMPUTER PROGRAMS FOR MONITORING PROCESSING IN A DATA PROCESSING SYSTEM OR NETWORK

Event-generation metadata is used to control the run-time environment of a system implementing a component architecture. A service provider program (40,100) implementing a component architecture is provided with event-generation functions that are configurable by the metadata to generate and send events. The metadata can be implemented as properties of an EJB deployment descriptor associated with a program component (30) for configuring event generation functions of an EJB container (40), to generate and send events to an events service (110). The events can be used to monitor processing of an application.
