A comprehensive approach to conceptual modelling and visual representation of log files

This paper proposes a comprehensive approach to conceptual log file modelling. It is based on the UML (Unified Modelling Language) class diagrams, which notation was extended to represent the main functionality of the nested structure of JSON (JavaScript Object Notation) log files. An implementation of the approach is illustrated in two domains: banking applications and networking. This study is a first step towards the sound development of a centralized log files management system. We use the ECS (Elastic Common Schema) initiative as a starting point. We also present the developed plugin to the StarUML software, which allows modelling logs in both UML and JSON formats.
