Conceptual modelling of log files: From a UML-based design to JSON files

In this paper, we describe an application of a recently proposed comprehensive UML-based (Unified Modeling Language) approach to the conceptual modelling of log files. On the real example, we built an ad hoc UML-based (class) diagram to represent the key features of the logs nested structure and generated an artifact (a template in JSON) based on ECS (Elastic Common Schema). We also describe plans for designing a specialized tool through a conjunction of the already developed artifacts. Presented work is a part of a broader study on the proposed initiative for the general concept of log files standardization. A clear structure of log data would allow more systematic development and more straightforward implementation and employment of the latest information systems, minimize anomalies, errors, and time delays.
