OpenTelemetry Has a Free Observability Framework for Traces Metrics and Logs

OpenTelemetry is the CNCF standard for observability. It provides a single set of APIs, SDKs, and tools for traces, metrics, and logs — vendor-neutral. What You Get for Free Traces — distributed tracing across services Metrics — counters, histograms, gauges Logs — structured logging with context Auto-instrumentation — many frameworks instrumented automatically Collector — receive, process, export telemetry Vendor-neutral — export to Jaeger, Prometheus, Datadog, Grafana 11 languages — Java, Python, Go, Node.js, .NET, Rust... Auto-Instrument Node.js const { NodeSDK } = require ( ' @opentelemetry/sdk-node ' ); const { OTLPTraceExporter } = require ( ' @opentelemetry/exporter-trace-otlp-http ' ); const sdk = new NodeSDK ({ traceExporter : new OTLPTraceExporter ({ url : ' http://localhost:4318/v1/traces ' }), }); sdk . start (); All HTTP requests, database calls, and framework operations are traced automatically.
