Observability Rules (OpenTelemetry)
Modern observability and monitoring patterns centered on OpenTelemetry (OTel). Covers the three pillars (traces, metrics, logs) with context propagation, OTel SDK architecture, OTLP protocol, distributed tracing with W3C Trace Context, metric instrument types (Counter, Histogram, Gauge, Timer, Exemplars), key metrics to monitor (application, business, infrastructure), metric naming conventions, log correlation, OTel Collector pipelines, Semantic Conventions, backend integration (Jaeger, Grafana Tempo, Loki, Prometheus), alerting rules, health check patterns (liveness, readiness, startup), SLO/SLI design, error budget management, and business metrics modeling. Use when implementing distributed tracing, setting up OTel instrumentation, configuring Collector pipelines, designing alerting strategies, implementing health checks, defining SLO/SLI targets, or integrating observability backends.
