You can't fix what you can't see. This unit covers the three pillars of observability: metrics (Prometheus), logging (ELK stack, Loki), and tracing (Jaeger). You will learn to instrument applications, set up dashboards (Grafana), and configure alerts to proactively detect issues.

Unit Learning Outcomes

• Understand the difference between monitoring, logging, and tracing.
• Instrument applications to expose metrics (Prometheus).
• Set up structured logging with correlation IDs.
• Create dashboards and alerts using Grafana.
• Implement distributed tracing for microservices.
