package main

import "github.com/segmentio/go-stats"
import "time"

func main() {
  s := stats.New()

  go func() {
    for {
      s.IncrBy("messages", 5)
      s.Incr("errors")
      time.Sleep(50 * time.Millisecond)
    }
  }()

  s.TickEvery(5 * time.Second)
  defer s.Stop()

  time.Sleep(time.Minute)
}

Outputs the ops/s, since last tick, and since the beginning of time.
