Package io.opentelemetry.api.trace

API for distributed tracing.

Distributed tracing, also called distributed request tracing, is a technique that helps debugging distributed applications.

Trace represents a tree of spans. A trace has a root span that encapsulates all the spans from start to end, and the children spans being the distinct calls invoked in between.

Span represents a single operation within a trace.

Spans are propagated in-process in the Context and between process using one of the wire propagation formats supported in the opentelemetry.trace.propagation package.

Interface Summary

Interface	Description
Span	An interface that represents a span.
SpanBuilder	SpanBuilder is used to construct Span instances which define arbitrary scopes of code that are sampled for distributed tracing as a single atomic unit.
SpanContext	A class that represents a span context.
Tracer	Tracer is the interface for Span creation and interaction with the in-process context.
TracerProvider	A registry for creating named Tracers.
TraceState	Carries tracing-system specific context in a list of key-value pairs.
TraceStateBuilder	A builder of TraceState.

Class Summary

Class	Description
SpanId	Helper methods for dealing with a span identifier.
TraceFlags	Helper methods for dealing with trace flags options.
TraceId	Helper methods for dealing with a trace identifier.

Enum Summary

Enum	Description
Span.Kind	Type of span.
StatusCode	The set of canonical status codes.
