Types

type HTTPStat

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

HTTPStat is the statistics tool for HTTP traffic.

func New

func New() *HTTPStat

New creates an HTTPStat.

func (*HTTPStat) Stat

func (hs *HTTPStat) Stat(m *Metric)

Stat stats the ctx.

func (*HTTPStat) Status

func (hs *HTTPStat) Status() *Status

Status returns HTTPStat Status, It assumes it is called every five seconds. https://github.com/rcrowley/go-metrics/blob/3113b8401b8a98917cde58f8bbd42a1b1c03b1fd/ewma.go#L98-L99

type Item

type Item struct {
	Path string `json:"path"`
	*Status
}

Item is the item of status.

type Metric

type Metric struct {
	StatusCode int
	Duration   time.Duration
	ReqSize    uint64
	RespSize   uint64
}

Metric is the package of statistics at once.

type RequestMetric

type RequestMetric struct {
	Count uint64  `json:"count"`
	M1    float64 `json:"m1"`
	M5    float64 `json:"m5"`
	M15   float64 `json:"m15"`

	ErrCount uint64  `json:"errCount"`
	M1Err    float64 `json:"m1Err"`
	M5Err    float64 `json:"m5Err"`
	M15Err   float64 `json:"m15Err"`

	M1ErrPercent  float64 `json:"m1ErrPercent"`
	M5ErrPercent  float64 `json:"m5ErrPercent"`
	M15ErrPercent float64 `json:"m15ErrPercent"`

	Min  uint64 `json:"min"`
	Max  uint64 `json:"max"`
	Mean uint64 `json:"mean"`

	P25  float64 `json:"p25"`
	P50  float64 `json:"p50"`
	P75  float64 `json:"p75"`
	P95  float64 `json:"p95"`
	P98  float64 `json:"p98"`
	P99  float64 `json:"p99"`
	P999 float64 `json:"p999"`

	ReqSize  uint64 `json:"reqSize"`
	RespSize uint64 `json:"respSize"`
}

RequestMetric contains request metrics.

type Status

type Status struct {
	RequestMetric
	Codes map[int]uint64 `json:"codes"`
}

Status contains all status generated by HTTPStat.

func (*Status) ToMetrics

func (s *Status) ToMetrics(service string) []*easemonitor.Metrics

ToMetrics implements easemonitor.Metricer.

type StatusCodeMetric

type StatusCodeMetric struct {
	Code  int    `json:"code"`
	Count uint64 `json:"cnt"`
}

StatusCodeMetric is the metrics of http status code.

type TopN

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

TopN is the statistics tool for HTTP traffic.

func NewTopN

func NewTopN(n int) *TopN

NewTopN creates a TopN.

func (*TopN) Stat

func (t *TopN) Stat(path string) *HTTPStat

Stat stats the ctx.

func (*TopN) Status

func (t *TopN) Status() []*Item

Status returns TopN Status, and resets all metrics.
