Functions

func AddConfigSchema

func AddConfigSchema(c interface {
	AddResource(url string, r io.Reader) error
}) error

AddConfigSchema adds the tracing schema to the compiler. The interface is specified instead of `jsonschema.Compiler` to allow the use of any jsonschema library fork or version.

func NewHandler

func NewHandler(handler http.Handler, operation string) http.Handler

func SetupJaeger

func SetupJaeger(t *Tracer, tracerName string) (trace.Tracer, error)

Optionally, Config.Providers.Jaeger.LocalAgentAddress can be set. NOTE: If Config.Providers.Jaeger.Sampling.ServerURL is not specfied, AlwaysSample is used.

func SetupOTLP

func SetupOTLP(t *Tracer, tracerName string) (trace.Tracer, error)

func SetupZipkin

func SetupZipkin(t *Tracer, tracerName string) (trace.Tracer, error)

func StringAttrs

func StringAttrs(attrs map[string]string) []attribute.KeyValue

func New

func New(name string, l *logrusx.Logger, c *Config) (*Tracer, error)

Creates a new tracer. If name is empty, a default tracer name is used instead. See: https://godocs.io/go.opentelemetry.io/otel/sdk/trace#TracerProvider.Tracer

func NewNoop

func NewNoop(l *logrusx.Logger, c *Config) *Tracer

Creates a new no-op tracer.

func (*Tracer) IsLoaded

func (t *Tracer) IsLoaded() bool

IsLoaded returns true if the tracer has been loaded.

func (*Tracer) Tracer

func (t *Tracer) Tracer() trace.Tracer

Returns the wrapped tracer.

type ZipkinConfig

type ZipkinConfig struct {
	ServerURL string         `json:"server_url"`
	Sampling  ZipkinSampling `json:"sampling"`
}

type ZipkinSampling

type ZipkinSampling struct {
	SamplingRatio float64 `json:"sampling_ratio"`
}
