ViVA: a visualization and analysis tool for distributed event-based systems
Youn Kyu Lee, Jae Young Bang, Joshua Garcia, Nenad Medvidović · 2014
Distributed event-based (DEB) systems are characterized by highly-decoupled components that communicate by exchanging messages. This form of communication enables flexible and scalable system composition but also reduces understandability and maintainability due to the indirect manner in which DEB components communicate. To tackle this problem, we present Visualizer for eVent-based Architectures, ViVA, a tool that effectively visualizes the large number of messages and dependencies that can be exchanged between components and the order in which the exchange of messages occur. In this paper, we describe the design, implementation, and key features of ViVA. (Demo video at http://youtu.be/jHVwuR5AYgA)
