Types

type JaegerConfig

type JaegerConfig struct {
	LocalAgentHostPort string
	SamplerType        string
	SamplerValue       float64
	SamplerServerURL   string
}

JaegerConfig encapsulates jaeger's configuration.

type Tracer

type Tracer struct {
	ServiceName  string
	Provider     string
	Logger       logrus.FieldLogger
	JaegerConfig *JaegerConfig
	// contains filtered or unexported fields
}

Tracer encapsulates tracing abilities.

func (*Tracer) Close

func (t *Tracer) Close()

Close closes the tracer.

func (*Tracer) IsLoaded

func (t *Tracer) IsLoaded() bool

IsLoaded returns true if the tracer has been loaded.

func (*Tracer) ServeHTTP

func (t *Tracer) ServeHTTP(rw http.ResponseWriter, r *http.Request, next http.HandlerFunc)

func (*Tracer) Setup

func (t *Tracer) Setup() error

Setup sets up the tracer. Currently supports jaeger.
