Overview ¶

Package echo is the calibrated target used by Stampede's accuracy benchmark. Each response is delayed by a value drawn from a known distribution, and the server records exactly how long it held every request, so a load generator's reported percentiles can be compared with ground truth.

Functions ¶

func ParseDist ¶

func ParseDist(s string) (dist, error)

ParseDist parses a delay distribution spec.

Types ¶

type Server ¶

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

Server is a calibrated echo handler.

func New ¶

func New(spec string, seed uint64) (*Server, error)

New builds a server for a distribution spec such as "lognormal:20ms:0.5".

func (*Server) Reset ¶

func (s *Server) Reset()

Reset clears recorded hold times.

func (*Server) ServeHTTP ¶

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

ServeHTTP implements http.Handler.

func (*Server) Stats ¶

func (s *Server) Stats() Stats

Stats returns exact percentiles of how long requests were held.

type Stats ¶

type Stats struct {
	Count int     `json:"count"`
	P50   float64 `json:"p50"`
	P90   float64 `json:"p90"`
	P95   float64 `json:"p95"`
	P99   float64 `json:"p99"`
	P999  float64 `json:"p999"`
	Max   float64 `json:"max"`
	Mean  float64 `json:"mean"`
}

Stats are exact percentiles of how long the server held requests.
