OpenTelemetry Has a Free Observability Framework — Traces, Metrics, and Logs Without Vendor Lock-in

OpenTelemetry (OTel) is the industry-standard observability framework — instrument once, export to any backend. What You Get for Free Traces — distributed tracing across services Metrics — counters, histograms, gauges Logs — structured logging with trace correlation Auto-instrumentation — zero-code instrumentation for popular frameworks SDKs — Java, Python, Go, JavaScript, .NET, Ruby, Rust, C++, PHP Collector — receive, process, export telemetry data Vendor-neutral — export to Jaeger, Prometheus, Grafana, Datadog, New Relic Context propagation — trace across HTTP, gRPC, messaging Quick Start (Node.js) npm install @opentelemetry/sdk-node @opentelemetry/auto-instrumentations-node import { NodeSDK } from ' @opentelemetry/sdk-node ' import { getNodeAutoInstrumentations } from ' @opentelemetry/auto-instrumentations-node ' const sdk = new NodeSDK ({ instrumentations : [ getNodeAutoInstrumentations ()] }) sdk . start () // That's it. HTTP, Express, pg, Redis — all auto-traced. Why Developers
