Elarva: A monitoring tool for Erlang

Abstract

The Larva monitoring tool has been successfully applied to a number of industrial Java systems, providing extra assurance of behaviour correctness. Given the increased interest in concurrent programming, we propose Elarva, an adaptation of Larva for monitoring programs written in Erlang, an established industry-strength concurrent language. Object-oriented Larva constructs have been translated to process-oriented setting, and the synchronous Larva monitoring semantics was altered to an asynchronous interpretation. We argue how this loosely-coupled runtime verification architecture still permits monitors to actuate recovery actions. © 2012 Springer-Verlag.
