Documentation

Overview

Package connstats counts the sockets and requests of the transports built by util.MakeTransport, so registry connection reuse is visible without a proxy in front of the registry. A proxy cannot see through TLS to a real registry.

Functions

func Trace 

func Trace(rt http.RoundTripper) http.RoundTripper

Trace records whether a request reused its connection, how long that connection sat idle first, and what the TLS handshake cost.

Types

type DialFunc 

type DialFunc func(ctx context.Context, network, addr string) (net.Conn, error)

DialFunc matches http.Transport.DialContext.

func WrapDial 

func WrapDial(dial DialFunc) DialFunc

WrapDial counts every socket the transport opens and closes. net/http reports neither to its caller, and httptrace has no close hook.

type Stats 

type Stats struct {
	SocketsOpened int64
	SocketsClosed int64
	SocketsOpen   int64
	PeakSockets   int64
	Requests      int64
	Reused        int64
	TLSHandshakes int64
	DialTime      time.Duration
	TLSTime       time.Duration
	IdleTime      time.Duration
}

Stats totals the registry traffic so far.

func Snapshot 

func Snapshot() Stats
