func HandleBasic

func HandleBasic(lg *zap.Logger, mux *http.ServeMux, server etcdserver.ServerPeer)

HandleBasic adds handlers to a mux for serving JSON etcd client requests that do not access the v2 store.

func HandleMetricsHealth

func HandleMetricsHealth(lg *zap.Logger, mux *http.ServeMux, srv etcdserver.ServerV2)

HandleMetricsHealth registers metrics and health handlers.

func HandleMetricsHealthForV3

func HandleMetricsHealthForV3(lg *zap.Logger, mux *http.ServeMux, srv *etcdserver.EtcdServer)

HandleMetricsHealthForV3 registers metrics and health handlers. it checks health by using v3 range request and its corresponding timeout.

func HandlePrometheus

func HandlePrometheus(mux *http.ServeMux)

HandlePrometheus registers prometheus handler on '/metrics'.

func NewHealthHandler

func NewHealthHandler(lg *zap.Logger, hfunc func() Health) http.HandlerFunc

NewHealthHandler handles '/health' requests.

func NewPeerHandler
