summary
Argues that true end-to-end observability is practical by combining APM with OpenTelemetry and shows a working demo: three Node.js services (books, orders, customers) instrumented with OpenTelemetry, traces exported to Jaeger, MongoDB calls captured, Docker containers used and requests sent via Postman to produce multi-service spans and a service-graph. Calls out costs of full tracing and recommends tail-based sampling, transactional E2E health checks and Apdex per critical route; demonstrates traces reveal which service and DB calls cause latency so problems are debuggable before users notice.
