Logging Architecture: Expanding InfoLogger into a Unified, Scalable Logging Platform

This report presents a scalable logging architecture for ALICE that unifies InfoLogger and DDS logs into a single platform. It introduces Fluent Bit for collection, OpenSearch for indexing, and Kafka for selective streaming, with Grafana dashboards and centralized alerting via Alertmanager. The design addresses current limitations such as the lack of DDS log integration and alerting, while enabling future extensions including anomaly detection, correlation graphs, and template mining.
