Abstract

Runtime monitoring is significantly essential for web service compositions. For a kind of composite services, nonfunctional properties, such as timed properties, are as important as functional properties and need to be monitored in runtime. In this paper, we extend Property Sequence Chart into timed Property Sequence Chart and propose a new approach to monitor two kinds of timed properties in web service compositions: the accomplished time of basic service operations and some additional timed assumptions of the composition process. Our approach is more intuitive than traditional monitoring approaches.
