Module init 

OpenTelemetry tracing initialization utilities

This gear sets up OpenTelemetry tracing and exports spans via OTLP (gRPC or HTTP) to collectors such as Jaeger, Uptrace, or the OTel Collector.

Functions

init_metrics_provider

Build a [SdkMeterProvider] from the resolved metrics exporter settings and register it as the global meter provider.

init_tracing

Initialize OpenTelemetry tracing from configuration and return a layer to be attached to tracing_subscriber.

otel_connectivity_probe

Build a tiny, separate OTLP pipeline and export a single span to verify connectivity. This does not depend on tracing_subscriber; it uses SDK directly.

shutdown_metrics

Gracefully shut down OpenTelemetry metrics, exporting the final interval.

shutdown_tracing

Gracefully shut down OpenTelemetry tracing, flushing the batch processor.
