Abstract

Erlang is a concurrent functional language, especially tailored for distributed and fault-tolerant software. Its strength has been demonstrated by several successful commercial applications. An important part of Erlang is its support for fault tolerance by implementing failure-recovery, through organising the processes of an Erlang system into trees of processes, in which parent nodes monitor the failure status of their children and are responsible for their restart. In this paper we present ongoing work on a tool that captures the static part of the global process structure of an application Erlang. The tool extracts the process structure from the applications source code, and presents it as a process creation graph. The extracted process structure provides a starting point for understanding and analysis of aspects such as fault handling in Erlang applications.
