How to use cloud-native observability with OpenTelemetry

· Category: Cloud Computing

Short answer

OpenTelemetry provides a unified standard for collecting telemetry data from cloud-native applications.

Steps

  1. Install the OpenTelemetry SDK for your language.
  2. Configure a tracer and meter provider.
  3. Instrument code with spans and metrics.
  4. Export data to backends like Jaeger, Prometheus, or cloud observability suites.

Tips

  • Auto-instrumentation reduces manual code changes.
  • Use semantic conventions for consistent attribute naming.
  • Sampling reduces overhead in high-throughput systems.

Common issues

  • Head-based sampling can miss rare errors; consider tail-based sampling.
  • Collector configuration complexity in large deployments.
