Abstract

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.
