Monitoring and Complex Event Processing
WSMX can be viewed as a vibrant events producer
events related to the broker services execution,
events related to the external Web Service invocations,
events related to the progress of processed execution semantics.
The events represent a rich source of knowledge which can facilitate profiling, optimization and reliability of the environment.
The monitoring and complex event processing subsystem exhibits following behavior
WSMX components have been instrumented to emit appropriate semantically-described events in regard to the computational process progress,
RDF-based CEP engine detects occurrences of specified event patterns and executes the appropriate actions de- fined for the detected event (e.g. update of the aggregated statistical measures, notification of the administrator about the successive operation failures)
