Learning Roadmap

  1. Install — pip install pico-otel[all] (Getting Started).
  2. See spans locally — default console exporter; hit an endpoint, read the span dump.
  3. Name your service — otel.service_name; find it in the span resource.
  4. Ship to a collector — set otel.endpoint; auto switches to OTLP.
  5. Metrics with actuator — install pico-actuator; curl /actuator/metrics (Architecture for the contract).
  6. Trim — drop extras you do not use; lower traces_sample_ratio under load.
