import (

    "runtime"

    "time"

    "fmt"

)

go func() {

        for {

            var m runtime.MemStats

            tick := time.After( * time.Second)

            select {

            case <-tick:

                runtime.ReadMemStats(&m)

                gb :=  *  * 1024.0

                logstr := fmt.Sprintf("\nAlloc = %v\tTotalAlloc = %v\tSys = %v\t NumGC = %v\n\n", float64(m.Alloc)/gb, float64(m.TotalAlloc)/gb, float64(m.Sys)/gb, m.NumGC)

                logger.Runtime.Info(logstr)

            }

        }

    }()
