Types

type Server

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

Server receives autoscaler statistics over WebSocket and sends them to a channel.

func New

func New(statsServerAddr string, statsCh chan<- *autoscaler.StatMessage, logger *zap.SugaredLogger) *Server

New creates a Server which will receive autoscaler statistics and forward them to statsCh until Shutdown is called.

func (*Server) Handler

func (s *Server) Handler(w http.ResponseWriter, r *http.Request)

Handler exposes a websocket handler for receiving stats from queue sidecar containers.

func (*Server) ListenAndServe

func (s *Server) ListenAndServe() error

ListenAndServe listens on the address s.addr and handles incoming connections. It blocks until the server fails or Shutdown is called. It returns an error or, if Shutdown was called, nil.

func (*Server) Shutdown

func (s *Server) Shutdown(timeout time.Duration)

Shutdown terminates the server gracefully for the given timeout period and then returns.
