Functions

func InitGlobalTracerProvider

func InitGlobalTracerProvider(tp TracerProvider, propagator propagation.TextMapPropagator)

InitGlobalTracerProvider initializes the global trace provider and global text map propagator with the provided values. This function edits the global (process-wide) OTEL trace provider, use with care!

func InitializeForTests

func InitializeForTests() (trace.Tracer, error)

func InitializeForTestsWithPropagatorFormat

func InitializeForTestsWithPropagatorFormat(propagatorFormat string) (trace.Tracer, error)

func NewTextMapPropagator

func NewTextMapPropagator(pf string) (propagation.TextMapPropagator, error)

NewTextMapPropagator takes a string-like value and returns the corresponding propagation.TextMapPropagator.

Types

type PropagatorFormat

type PropagatorFormat string

PropagatorFormat is an enum-like type representing all the supported OTEL propagator formats.

const (
	PropagatorFormatJaeger PropagatorFormat = "jaeger"
	PropagatorFormatW3C    PropagatorFormat = "w3c"
)

type RemoteSamplerOptions

type RemoteSamplerOptions struct {
	URL         string
	ServiceName string
}

type SamplerOptions

type SamplerOptions struct {
	SamplerType SamplerType
	Param       float64
	Remote      RemoteSamplerOptions
}

type SamplerType

type SamplerType string

const (
	SamplerTypeNone          SamplerType = ""
	SamplerTypeConst         SamplerType = "const"
	SamplerTypeProbabilistic SamplerType = "probabilistic"
	SamplerTypeRateLimiting  SamplerType = "rateLimiting"
	SamplerTypeRemote        SamplerType = "remote"
)

type TracerProvider

type TracerProvider interface {
	trace.TracerProvider

	// Shutdown performs cleanup operations to ensure the trace provider is disposed correctly.
	Shutdown(ctx context.Context) error
}

TracerProvider provides a tracer that can be used to instrument a plugin with tracing.

func NewTracerProvider

func NewTracerProvider(address string, samplerOpts SamplerOptions, opts tracing.Opts) (TracerProvider, error)

NewTracerProvider returns a new TracerProvider depending on the specified address. It returns a noopTracerProvider if the address is empty, otherwise it returns a new OpenTelemetry TracerProvider.
