Certain example embodiments relate to techniques for investigating event streams in complex event processing (CEP) environments. Input events from one or more input event streams and query registration-related events from a registration event stream are received. Query registration-related events are associated with actions taken with respect to queries performed on the input event stream(s). Event-based profiles are developed by subjecting the received input events to a profiling CEP engine. Event-based profiles include data mining related and/or statistical characteristics for each input event stream. Query-based profiles are developed by subjecting the received query registration-related events to the CEP engine. Query-based profiles include data indicative of how relevant the queries performed on the input event stream(s) are and/or how those queries are relevant to the input event stream(s) on which they are performed. Query registration-related events are generated when a query on the input event stream(s) is registered, deregistered, etc.

Systems and/or methods for investigating event streams in complex event processing (CEP) applications

Certain example embodiments address issues associated with erroneous events produced in Complex Event Processing (CEP) applications. An error handler is controlled to at least: receive, via an event bus, events from external input event sources; receive, via the event bus, error events from an application configured to process events received from the event bus, and to provide to the event bus results obtained from processing received events, and error events corresponding to errors detected at its input and/or processing layer(s); generate, for a given error, an error analysis event and an error impact event by executing a CEP query on at least a corresponding received error event; and provide to the event bus generated error analysis events and generated error impact events. Error analysis events describe for administrators detailed information analyzing corresponding errors. Error impact events describe for business users impacts corresponding errors have for their business user applications.
