This is the module providing the OpenTelemetry protocol for exporting traces. It can be configured through its application environment, the OS environment or directly through a map of options passed when setting up the exporter in the batch processor.

opentelemetry_exporter application enevironment options are:

• otlp_endpoint: The URL to send traces and metrics to, for traces the path v1/traces is appended to the path in the URL.
• otlp_traces_endpoint: URL to send only traces to. This takes precedence for exporting traces and the path of the URL is kept as is, no suffix is appended.
• otlp_headers: Additional headers to add to export requests.
• otlp_traces_headers: Additional headers to add to only trace export %% requests.

There also corresponding OS environment variables can also set those configuration values:

• OTEL_EXPORTER_OTLP_ENDPOINT
• OTEL_EXPORTER_OTLP_TRACES_ENDPOINT
• OTEL_EXPORTER_OTLP_HEADERS
• OTEL_EXPORTER_OTLP_TRACES_HEADERS
