To further enrich log data for automated observability, it’s necessary to dynamically tie logs to distributed traces on the code level, user sessions in the app front-end, and the topology of your IT landscape. Collecting logs that aren’t relevant to their business case creates noise, overloads congested networks, and slows down teams.
