Types ¶

type Measurement ¶

type Measurement struct {
	Host    string
	Port    int
	Timeout int
	Runs    int
	Wait    int
	// contains filtered or unexported fields
}

Measurements represents a new tcplatency measurement

func NewMeasurement ¶

func NewMeasurement(host string, port int, timeout int, runs int, wait int) *Measurement

func (*Measurement) AvgLatency ¶

func (m *Measurement) AvgLatency() float64

AvgLatency returns the average tcp latency

func (*Measurement) DialTCP ¶

func (m *Measurement) DialTCP() *TCPResponse

DialTCP calculates a latency point using sockets.

func (*Measurement) IsFinished ¶

func (m *Measurement) IsFinished() bool

IsFinished returns true when all tcp ping runs have been executed, false if not

func (*Measurement) MaxLatency ¶

func (m *Measurement) MaxLatency() float64

MaxLatency returns the max latency

func (*Measurement) MinLatency ¶

func (m *Measurement) MinLatency() float64

MinLatency returns the min latency

func (*Measurement) Result ¶

func (m *Measurement) Result() MeasurementResult

Result returns a new measurement result. Can be used to summarize results of multiple measurements

func (*Measurement) StdDevLatency ¶

func (m *Measurement) StdDevLatency() float64

StdDevLatency calculates an average of how far each latency is from the mean latency. The higher MedianDerivation is, the more variable the latency is over time.

type MeasurementResult ¶

type MeasurementResult struct {
	Successful int
	Failed     int
	Count      int
	Average    float64
	Max        float64
	Min        float64
	StdDev     float64
}

MeasurementResult represents a new measurement result

func Measure ¶

func Measure(host string, port int, timeout int, runs int, wait int) MeasurementResult

type TCPResponse ¶

type TCPResponse struct {
	Host     string
	Port     int
	Sequence int
	Timeout  int
	Latency  float64
	Failed   bool
}

func (*TCPResponse) String ¶

func (tcp *TCPResponse) String() string
