Why
The OTLP export feature lacked end-user documentation and runnable examples, making it hard to discover and configure. Additionally, a bug caused the exporter to crash when
OTEL_EXPORTER_OTLP_ENDPOINTwas set to a base URL without a path (http://host:4318), becauseopentelemetry-exporter-otlpexpects the path to be included.What
## OTLP Exportsection covering quick start, all supported environment variables, YAML configuration, config precedence, TLS/mTLS setup, and a troubleshooting guide.# Made with Bobcomment.resolve_otlp_endpoint— fixed to append/v1/tracesto user-supplied base URLs that have no path, matching the OTLP spec behaviour forOTEL_EXPORTER_OTLP_ENDPOINT.host_agent_reporting_observer_test.rb— two new tests: base URL gets path appended; fully-qualified URL is passed through unchanged.
