A Framework for Generating and Deploying Dynamic Performance Monitors for Self-Adaptive Software Systems

Abstract

Software systems have become a fundamental support for everyday activities, in both personal and business contexts. On the one hand, individuals rely on software to accomplish duties and responsibilities across their lifestyle; multimedia applications have become part of their daily habits, including social networks, messaging, and online streaming of music, movies, and TV shows. On the other hand, companies are increasingly dependent on software technology to support their business objectives. Software is not only a base tool to cope with tedious administrative tasks, but also the personal and business infrastructure to deliver value-added services to customers. These two perspectives show the increasing dependence of users on their software applications and, as a result, their increasing quality expectations on the provided application services (e.g., users want to see video streaming in one smooth playback). Thus, in order to promote business strengthening, stakeholders are concerned with the fulfillment of certain quality attributes (QA), especially those sensibly impacting the system behavior as perceived by the client.
