Types

type Collector

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

Collector manages the collection and storage of statistical data

func InitStatsCollector

func InitStatsCollector() *Collector

func (*Collector) Collect

func (sc *Collector) Collect(interval time.Duration)

Collect starts collecting statistical data

func (*Collector) GetStats

func (sc *Collector) GetStats() []Stats

GetStats returns all the collected statistical data

type NetStats

type NetStats struct {
	LastSent uint64
	LastRecv uint64
	LastTime time.Time
}
