Functions

func ForwarderDims

func ForwarderDims(name string, typ string) map[string]string

ForwarderDims are the common stat dimensions we expect on forwarder protocols

func ListenerDims

func ListenerDims(name string, typ string) map[string]string

ListenerDims are the common stat dimensions we expect on listener protocols

Types

type CloseableHealthCheck

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

CloseableHealthCheck is a helper class intended to be used as an anonymous field

func (*CloseableHealthCheck) CloseHealthCheck

func (c *CloseableHealthCheck) CloseHealthCheck()

CloseHealthCheck is called to change the status of the healthcheck from 200 to 404 and close the connection

func (*CloseableHealthCheck) HealthDatapoints

func (c *CloseableHealthCheck) HealthDatapoints() []*datapoint.Datapoint

HealthDatapoints returns the total health checks done

func (*CloseableHealthCheck) SetupHealthCheck

func (c *CloseableHealthCheck) SetupHealthCheck(healthCheck *string, r *mux.Router, logger log.Logger)

SetupHealthCheck sets up a closeable healthcheck, when open returns 200, when closed returns 404 and close the connection

type DatapointForwarder

type DatapointForwarder interface {
	sfxclient.Collector
	io.Closer
	dpsink.DSink
}

DatapointForwarder can send datapoints and not events

type Forwarder

type Forwarder interface {
	dpsink.Sink
	Pipeline
	sfxclient.Collector
	io.Closer
}

Forwarder is the basic interface endpoints must support for the proxy to forward to them

type HealthChecker

type HealthChecker interface {
	CloseHealthCheck()
}

HealthChecker interface is anything that exports a healthcheck that would need to be invalidated on graceful shutdown

type Listener

type Listener interface {
	sfxclient.Collector
	io.Closer
	HealthChecker
}

Listener is the basic interface anything that listens for new metrics must implement

type Pipeline

type Pipeline interface {
	Pipeline() int64
}

Pipeline returns the number of items still in flight that need to be drained

type UneventfulForwarder

type UneventfulForwarder struct {
	DatapointForwarder
}

UneventfulForwarder converts a datapoint only forwarder into a datapoint/event forwarder

func (*UneventfulForwarder) AddEvents

func (u *UneventfulForwarder) AddEvents(ctx context.Context, events []*event.Event) error

AddEvents does nothing and returns nil

func (*UneventfulForwarder) Pipeline

func (u *UneventfulForwarder) Pipeline() int64

Pipeline returns zero since UneventfulForwarder doesn't have it's own buffer
