Module opentelemetry::sdk::trace

OpenTelemetry Trace SDK

The tracing SDK consist of a few main structs:

• The Tracer struct which performs all tracing operations.
• The Span struct with is a mutable object storing information about the current operation execution.
• The TracerProvider struct which configures and produces Tracers.

Structs

BatchConfig

Batch span processor configuration

BatchSpanProcessor

A SpanProcessor that asynchronously buffers finished spans and reports them at a preconfigured interval.

BatchSpanProcessorBuilder

A builder for creating BatchSpanProcessor instances.

Builder

Builder for provider attributes.

Config

Tracer configuration

EvictedHashMap

A hash map with a capped number of attributes that retains the most recently set entries.

EvictedQueue

This queue maintains an ordered list of elements, and a count of dropped elements. Elements are removed from the queue in a first in first out fashion.

IdGenerator

Default crate::trace::IdGenerator implementation. Generates Trace and Span ids using a random number generator.

SamplingResult

The result of sampling logic for a given Span.

SimpleSpanProcessor

A SpanProcessor that exports synchronously when spans are finished.

Span

Single operation within a trace.

SpanLimits

Span limit configuration to keep attributes, events and links to a span in a reasonable number.

Tracer

Tracer implementation to create and manage spans

TracerProvider

Creator and registry of named Tracer instances.

XrayIdGenerator

Generates AWS X-Ray compliant Trace and Span ids.

Enums

BatchMessage

Messages sent between application thread and batch span processor’s work thread.

Sampler

Sampling options

SamplingDecision

Decision about whether or not to sample

Traits

ShouldSample

The ShouldSample interface allows implementations to provide samplers which will return a sampling SamplingResult based on information that is typically available just before the Span was created.

SpanProcessor

SpanProcessor is an interface which allows hooks for span start and end method invocations. The span processors are invoked only when is_recording is true.

TraceRuntime

Trace runtime is an extension to Runtime. Currently it provides a channel that used by BatchSpanProcessor.

TrySend

TrySend is an abstraction of sender that is capable to send BatchMessage with reference.
