Implementation plan:

  1. What is observability — understanding system behavior from external outputs
  2. The three pillars: logs, metrics, traces
  3. Logs — what happened (events)
  4. Metrics — how the system is performing (counters, gauges, histograms)
  5. Traces — the path of a request through services
  6. Why all three are needed — each answers different questions
  7. Observability in microservices vs monoliths
