summary
Shows how Rails default multiline logs become structured JSON using Lograge, how logs stream to Elasticsearch and are explored in Kibana, and how a consistent log schema with request_id user_id path duration and error fields lets you ask precise queries. Demonstrates concrete searches that pinpoint a slow endpoint, links traces across services, and reports a realistic case where troubleshooting time drops from hours to minutes (mean time to diagnose from hours to minutes).
