func (*Agent) HTTPAddr added in v1.1.0

func (a *Agent) HTTPAddr() string

HTTPAddr returns the address that HTTP server is listening on

func (*Agent) Run

func (a *Agent) Run() error

func (*Agent) Stop

func (a *Agent) Stop()

Stop forces all agent go routines to exit.

type Builder

type Builder struct {
	Processors []ProcessorConfiguration `yaml:"processors"`
	HTTPServer HTTPServerConfiguration  `yaml:"httpServer"`

	tchreporter.Builder `yaml:",inline"`
	// contains filtered or unexported fields
}

Builder Struct to hold configurations

func (*Builder) CreateAgent

func (b *Builder) CreateAgent(logger *zap.Logger) (*Agent, error)

type HTTPServerConfiguration

type HTTPServerConfiguration struct {
	HostPort string `yaml:"hostPort" validate:"nonzero"`
}

HTTPServerConfiguration holds config for a server providing sampling strategies and baggage restrictions to clients

func (HTTPServerConfiguration) GetHTTPServer

func (c HTTPServerConfiguration) GetHTTPServer(svc string, channel *tchannel.Channel, mFactory metrics.Factory) *http.Server
