All Classes

Class	Description
B3Propagation<K>	Implements B3 Propagation
B3Propagation.FactoryBuilder	Defaults to B3Propagation.Format.MULTI for client/server spans and B3Propagation.Format.SINGLE_NO_PARENT for messaging.
B3Propagation.Format	Describes the formats used to inject headers.
B3SingleFormat	This format corresponds to the propagation key "b3" (or "B3"), which delimits fields in the following manner.
B3SinglePropagation	Deprecated. Since 5.9, use B3Propagation.newFactoryBuilder() to control inject formats.
BaggageField	Defines a trace context scoped field, usually but not always analogous to an HTTP header.
BaggageField.ValueUpdater	Used to decouple baggage value updates from TraceContext or TraceContextOrSamplingFlags storage.
BaggageFields	This contains pre-defined fields, such as BaggageFields.TRACE_ID and a way to create a constant field.
BaggagePropagation<K>	This implements in-process and remote baggage propagation.
BaggagePropagation.FactoryBuilder
BaggagePropagationConfig	Holds BaggagePropagation configuration.
BaggagePropagationConfig.SingleBaggageField	Holds BaggagePropagation configuration for a baggage field.
BaggagePropagationConfig.SingleBaggageField.Builder
BaggagePropagationCustomizer	This allows configuration plugins to collaborate on building an instance of BaggagePropagation.Factory.
BoundarySampler	This sampler is appropriate for high-traffic instrumentation (ex edge web servers that each receive >100K requests) who provision random trace ids, and make the sampling decision only once.
Clock	Epoch microseconds used for Span.start(long), Span.finish(long) and Span.annotate(long, String).
CorrelationScopeConfig	Holds CorrelationScopeDecorator configuration.
CorrelationScopeConfig.SingleCorrelationField	Holds CorrelationScopeDecorator configuration for a baggage field.
CorrelationScopeConfig.SingleCorrelationField.Builder
CorrelationScopeCustomizer	This allows configuration plugins to collaborate on building an instance of CorrelationScopeDecorator.
CorrelationScopeDecorator	Synchronizes fields such as BaggageFields.TRACE_ID with a correlation context, such as logging through decoration of a scope.
CorrelationScopeDecorator.Builder	Defaults to BaggageFields.TRACE_ID and BaggageFields.SPAN_ID.
CountingSampler	This sampler is appropriate for low-traffic instrumentation (ex servers that each receive <100K requests), or those who do not provision random trace ids.
CurrentSpanCustomizer	Provides a mechanism for end users to be able to customise the current span.
CurrentTraceContext	This makes a given span the current span by placing it in scope (usually but not always a thread local scope).
CurrentTraceContext.Builder	Implementations of this allow standardized configuration, for example scope decoration.
CurrentTraceContext.Default	Default implementation which is backed by a static thread local.
CurrentTraceContext.Scope	A span remains in the scope it was bound to until close is called.
CurrentTraceContext.ScopeDecorator	Use this to add features such as thread checks or log correlation when a scope is created or closed.
CurrentTraceContextCustomizer	This allows configuration plugins to collaborate on building an instance of CurrentTraceContext.
DeclarativeSampler<M>	This is an implementation of how to decide whether to trace a request using annotations on a java method.
DeclarativeSampler.ProbabilityOfMethod<M>
DeclarativeSampler.RateForMethod<M>	Deprecated. since 5.8, use DeclarativeSampler.ProbabilityOfMethod
DeclarativeSampler.RateOfMethod<M>
ErrorParser	Deprecated. Since 5.12 Use Tags#ERROR or defer to ZipkinSpanHandler
ExtraFieldCustomizer	Deprecated. Since 5.11 use BaggagePropagationCustomizer
ExtraFieldPropagation<K>	Deprecated. Since 5.11 use BaggagePropagation
ExtraFieldPropagation.Factory	Deprecated. Since 5.11 use Propagation.Factory
ExtraFieldPropagation.FactoryBuilder	Deprecated. Since 5.11 use BaggagePropagation.FactoryBuilder
FinishedSpanHandler	Deprecated. Since 5.12 use SpanHandler.end(TraceContext, MutableSpan, Cause) with SpanHandler.Cause.FINISHED
Matcher<P>	Returns true if this rule matches the input parameters
Matchers	Convenience functions to compose matchers for ParameterizedSampler.
MutableSpan	This represents a span except for its TraceContext.
MutableSpan.AnnotationConsumer<T>
MutableSpan.AnnotationUpdater
MutableSpan.TagConsumer<T>
MutableSpan.TagUpdater
MutableSpanBytesEncoder	Similar to zipkin2.MutableSpan.SpanBytesEncoder except no Zipkin dependency.
NoopSpanCustomizer	Performs no operations as the span represented by this is not sampled to report to the tracing system.
ParameterizedSampler<P>	This is an implementation of how to decide whether to trace a request using ordered rules.
ParameterizedSampler.Builder<P>
ParameterizedSampler.Rule<P>	Deprecated. Since 5.8, use ParameterizedSampler.Builder.putRule(Matcher, Sampler)
Propagation<K>	Injects and extracts trace identifiers as text into requests that travel in-band across process boundaries.
Propagation.Factory
Propagation.Getter<R,K>	Gets the first value of the given propagation key or returns null.
Propagation.KeyFactory<K>	Deprecated. since 5.12 non-string keys are no longer supported
Propagation.RemoteGetter<R>	Used as an input to Propagation.extractor(Getter) extract the trace context and any baggage from propagated fields.
Propagation.RemoteSetter<R>	Used as an input to Propagation.injector(Setter) inject the trace context and any baggage as propagated fields.
Propagation.Setter<R,K>	Replaces a propagated key with the given value.
RateLimitingSampler	The rate-limited sampler allows you to choose an amount of traces to accept on a per-second interval.
Request	Abstract request type used for parsing and sampling.
Response	Abstract response type used for parsing.
Sampler	Sampler is responsible for deciding if a particular trace should be "sampled", i.e.
SamplerFunction<T>	Decides whether to start a new trace based on request properties such as an HTTP path.
SamplerFunctions	Convenience sampling functions.
SamplingFlags
SamplingFlags.Builder	Deprecated. prefer using constants.
ScopedSpan	Used to model the latency of an operation within a method block.
Span	Subtype of SpanCustomizer which can capture latency and remote context of an operation.
Span.Kind
SpanCustomizer	Simple interface users can customize a span with.
SpanHandler	This tracks one recording of a TraceContext.
SpanHandler.Cause	What ended the data collection?
StrictCurrentTraceContext	Useful when developing instrumentation as state is enforced more strictly.
StrictCurrentTraceContext.Builder
StrictScopeDecorator	Useful when developing instrumentation as state is enforced more strictly.
Tag<I>	This is a centralized type to parse a tag into any variant of a span.
Tags	Standard tags used in parsers
ThreadLocalCurrentTraceContext	In-process trace context propagation backed by a static thread local.
ThreadLocalCurrentTraceContext.Builder
ThreadLocalSpan	This type allows you to place a span in scope in one method and access it in another without using an explicit request parameter.
TraceContext	Contains trace identifiers and sampling data propagated in and out-of-process.
TraceContext.Builder
TraceContext.Extractor<R>	Used to continue an incoming trace.
TraceContext.Injector<R>	Used to send the trace context downstream.
TraceContextOrSamplingFlags	Union type that contains only one of trace context, trace ID context or sampling flags.
TraceContextOrSamplingFlags.Builder
TraceIdContext	Contains inbound trace ID and sampling flags, used when users control the root trace ID, but not the span ID (ex Amazon X-Ray or other correlation).
TraceIdContext.Builder
Tracer	Using a tracer, you can create a root span capturing the critical path of a request.
Tracer.SpanInScope	A span remains in the scope it was bound to until close is called.
Tracing	This provides utilities needed for trace instrumentation.
Tracing.Builder
TracingCustomizer	This allows configuration plugins to collaborate on building an instance of Tracing.
