A taxonomy for classifying runtime verification tools

Over the last 20 years, runtime verification (RV) has grown into a diverse and active field, which has stimulated the development of numerous theoretical frameworks and practical tools. Many of the tools are at first sight very different and challenging to compare. Yet, there are similarities. In this work, we classify RV tools within a high-level taxonomy of concepts. We first present this taxonomy and discuss its different dimensions. Then, we survey the existing RV tools and, where possible with the support of tool authors, classify them according to the taxonomy. While the classification continually evolves, this article presents a snapshot with 60 state-of-the-art RV tools. We believe that this work is an important step in establishing a common terminology in RV and enabling a meaningful comparison of existing RV tools.
