Observability Developers Actually Use
OpenTelemetry, Prometheus, and distributed tracing get endorsements because they reveal correlations without ceremony. Instrumentation should fit into frameworks and libraries, not burden teams with bespoke plumbing. Good dashboards whisper insights rather than scream confusion. With exemplars, RED and USE methods, and trace-linked logs, engineers jump from symptom to cause quickly. When investigation is friendly, on-call becomes humane, and teams deploy fearlessly, knowing they can detect, diagnose, and fix within minutes.
