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)
