Axial.Telemetry.JavaScript Reference

Axial.Telemetry.JavaScript emits spans through a host-supplied @opentelemetry/api object. Use installNamed with an application instrumentation scope for user workflows; install uses the default Axial scope. The package does not import or configure the JavaScript SDK.

Surface	Purpose
OtelContext, Span, Tracer, TraceApi, ContextApi, OpenTelemetryApi	Structural bindings for the API object supplied by the host
Otel.installNamed, Otel.install, and Otel.installWith	Install the tracer used by subsequent Flow telemetry
Otel.uninstall	Remove the installed tracer
Otel.trace and Otel.traceWith	Wrap a workflow in an OpenTelemetry span
FiberTelemetry.observer and FiberTelemetry.observe	Report fiber defects through the installed tracer
FiberTelemetry.observerWithSpans and FiberTelemetry.observeWithSpans	Create one span for each forked fiber

Ambient attributes use Axial.Telemetry.Context from core on both platforms; OtelContext is only the opaque context object owned by @opentelemetry/api.

See JavaScript Telemetry for SDK setup, context propagation, and usage.
