From Log Hell to Log Heaven 🚀 | Set Up Centralized Logging with Loki, Grafana & Node.js
🚨 Production crash? Logs scattered across containers?
Learn how to set up centralized logging with Loki and Grafana to make debugging effortless and efficient. This is the modern observability stack every developer and DevOps engineer needs.
In this step-by-step tutorial, you’ll learn:
✅ How to set up a complete observability pipeline with Loki for log aggregation and Grafana for visualization
✅ Configure Winston logger for structured JSON logging in a Node.js + NestJS application
✅ Send logs to Loki and store them in AWS S3
✅ Query logs by user ID, request ID, log level, and more — right inside Grafana
✅ Avoid the pain of grepping logs across containers or SSHing into multiple machines
This is how centralized logging should be done in modern cloud-native applications using Docker and microservices.
