Module init 

OpenTelemetry tracing initialization utilities

This module 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

Initialize OpenTelemetry metrics by registering the given [SdkMeterProvider] 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. In opentelemetry 0.31 there is no global shutdown_meter_provider(). Keep a handle to SdkMeterProvider in your app state and call shutdown() during graceful shutdown. This function remains a no-op for compatibility.

shutdown_tracing

Gracefully shut down OpenTelemetry tracing. In opentelemetry 0.31 there is no global shutdown_tracer_provider(). Keep a handle to SdkTracerProvider in your app state and call shutdown() during graceful shutdown. This function remains a no-op for compatibility.
