Types

type Sender

type Sender struct {
	// contains filtered or unexported fields
}

Sender is responsible for submitting data to the collector endpoint.

func NewSender

func NewSender(ctx agent.AgentContext) *Sender

func (*Sender) RegisterSampler

func (s *Sender) RegisterSampler(sampler sampler.Sampler)

func (*Sender) Start

func (s *Sender) Start() (err error)

Start will register the sender with the collector, then start a couple of background routines to handle incoming data and post it to the server periodically.

func (*Sender) Stop

func (s *Sender) Stop() (err error)

Stop will gracefully shut down all sending processes and reset the state of the sender. After Stop() returns, it is safe to call Start() again on the same sender instance.
