Build production observability in 2026 with structured logging, Prometheus metrics, Grafana dashboards, distributed tracing via OpenTelemetry, and alerting rules that catch issues before users notice.
Implement OpenTelemetry for vendor-neutral distributed tracing, metrics, and logs: SDK setup for Node.js and Python, collector configuration, Jaeger integration, and context propagation across microservices.
Master end-to-end LLM observability with OpenTelemetry spans, trace correlation, adaptive sampling, and anomaly detection to catch production issues before users do.
Complete OpenTelemetry setup for Node.js, auto-instrumentation, custom spans, trace propagation, OTLP export to Tempo/Jaeger, sampling strategies, and production alerting.
