Module otel 

OpenTelemetry OTLP tracer — init once at launch, read globally.

Call init_tracer from ArclyObservabilityPlugin::on_init. Call opentelemetry::global::shutdown_tracer_provider() in on_shutdown to flush any buffered spans before the process exits.

Structs

OtelConfig

Configuration for the OTLP span exporter.

Functions

init_tracer

Initialise the global OpenTelemetry tracer provider with a batch OTLP gRPC exporter. Safe to call once — subsequent calls on the same process are no-ops because set_tracer_provider is idempotent on the global.

parent_context_from

Build an OpenTelemetry Context that represents the parent of the span about to be created for this request.
