Thanks to the huge amount of excellent work done by Duncan Paul Attard and Adrian Francalanza, we now have a tutorial on detectEr that some of you might want to check out. See this web page for all the material, tool download and links to the videos of the tutorial Duncan delivered at the DisCoTec 2021 Tutorial Day.
detectEr is a runtime verification tool for asynchronous component systems that run on the Erlang Virtual Machine. It also supports monitoring systems that can execute outside of the EVM, so long as these can produce traces that are formatted in a way that is parsable by detectEr. The tool itself is developed in Erlang, and is the product of five years of theoretical and practical development. (Erlang is a programming language used to build massively scalable soft real-time systems with requirements on high availability.)
