Quick Answer
Centralized logging: use ILogger everywhere. Configure Serilog: WriteTo.File(), WriteTo.Seq(), WriteTo.Elasticsearch(). Structure log entries with context (UserId, CorrelationId, RequestPath). Use Serilog.Enrichers.CorrelationId. Forward to centralized system (ELK, Datadog, Application Insights). Configure log levels per namespace in appsettings.json to control verbosity.
