OpenTelemetry Has a Free API That Instruments Your Entire Stack in One Standard

OpenTelemetry is the vendor-neutral observability framework. Traces, metrics, and logs — one SDK, any backend (Grafana, Datadog, Jaeger, Honeycomb). What Is OpenTelemetry? OpenTelemetry (OTel) is the CNCF standard for collecting telemetry data. Instead of vendor-specific agents, use one SDK that works with every observability platform. Quick Start (Node.js) npm install @opentelemetry/sdk-node @opentelemetry/auto-instrumentations-node @opentelemetry/exporter-trace-otlp-http // tracing.ts — run before your app import { NodeSDK } from ' @opentelemetry/sdk-node ' import { getNodeAutoInstrumentations } from ' @opentelemetry/auto-instrumentations-node ' import { OTLPTraceExporter } from ' @opentelemetry/exporter-trace-otlp-http ' const sdk = new NodeSDK ({ traceExporter : new OTLPTraceExporter ({ url : ' http://localhost:4318/v1/traces ' }), instrumentations : [ getNodeAutoInstrumentations ()], serviceName : ' my-api ' , }) sdk . start () # Run with auto-instrumentation node -r ./tracing.ts
