Event Logging in an Industrial Development Process: Practices and Reengineering Challenges

This paper discusses our preliminary analysis of event logging practices adopted in a large-scale industrial development process at Selex ES, a top-leading Finmeccanica company in electronic and information technologies for defense systems, aerospace, and land security. The analysis aims to support log reengineering activities that are currently conducted at SELEX ES. At time being, some of the issues described in the paper have been fixed by system developers. Analysis encompasses total around 50+ millions lines of log produced by an Air Traffic Control (ATC) system. Analysis reveals that event logging is not strictly regulated by company-wide practices, which results into heterogeneous logs across different development teams. We introduce our ongoing effort at developing an automatic support to browse collected logs along with a uniform logging policy supplementing the reengineering process.
