RESMETRIC: Analyzing Resilience to Enable Research on Antifragility

Abstract: A key feature in self-adaptive systems is resilience, which is an ongoing research topic. Recently, the community started to explore antifragility, which describes the improvement of resilience over time. While there are model-agnostic resilience metrics, there is currently no out-of-the-box tool for researchers and practitioners to determine to which degree their system is resilient. To facilitate research on antifragility, we present ResMetric, a model-agnostic tool that calculates and visualizes various resilience metrics based on the quality of service over time. With ResMetric, researchers can evaluate their definition of resilience and antifragility. This paper highlights how ResMetric can be employed by demonstrating its use in a case study on gas detection.
