Kacper Kotowicz focused on enhancing observability and monitoring across the eclipse-tractusx/tractus-x-umbrella and tractusx-edc repositories, delivering features such as structured JSON logging, OpenTelemetry integration, and Log4j2-based event handling. He implemented distributed tracing, log aggregation, and metrics collection using Java, Helm, and Kubernetes, enabling end-to-end visibility and faster troubleshooting. His work included aligning deployments with TAP 7.2 observability requirements, updating Helm charts and Gradle dependencies, and introducing configuration fixes to ensure reliable metric scraping. By coordinating cross-repository updates and maintaining clear documentation, Kacper established a robust, unified observability baseline that improved system reliability and maintainability.
