A Pattern-Based Approach for Monitor Adaptation

Monitoring of service-based systems can be used to assist with the verification of the behaviour of the system, and the quality and contextual information of the services participating in a system. In this paper, we present a pattern-based approach to support monitor adaptation: adaptation of monitor rules used by a monitor tool. Our work focuses on monitor adaptation due to changes in the context characteristics of the user interacting with the system and the set of services used by the system. The monitor adaptation is based on the use of patterns represented in Event Calculus for different user context types such as role, skills, needs, preferences, and cognition, as well as location, time, and environment.
