Fast identification of failure causes in logs using EventId in .NET Core, using acts for the unified register of internet advertising

▤ Summary

This article explains how to speed up root-cause analysis in .NET Core logs by using EventId and structured logging. It shows how EventId helps distinguish similar log lines and makes searching in tools like Kibana, ELK, grep, and Excel more efficient. It also covers how BeginScope works in ILogger, why scopes persist across async calls, and how to avoid losing context with Task.Run. The article closes with practical examples for naming EventIds and using them in Web API and MediatR-based applications.
