Overview

Package otel provides lightweight OpenTelemetry setup for pi-go, driven entirely by environment variables sourced from ~/.pi-go/.env so secrets never appear in the process environment.

The following env vars are consumed: 

EL_SERVICE_NAME        defaults to "pi-go"
OTEL_EXPORTER_OTLP_ENDPOINT  collector endpoint (e.g. https://collector:4317)
OTEL_EXPORTER_OTLP_PROTOCOL  "grpc" or "http" (default)
OTEL_TRACES_EXPORTER    "otlp" (default), "console", or "none"

If no exporter is configured, tracing is a no-op (tracer returns no-op spans).
