A general-purpose tool for debugging and analyzing programs, in development and production. Example:

package main

import (
    "os/syscall"
    "os"
    "time"

)

func main() {
    s := swat.Start(
        swat.DumpGoroutine().
            OnSignal(syscall.SIGUSR1).
            ToWriter(os.Stdout),
        swat.DumpHeap().
            After(5*time.Minute).
            Every(time.Second).
            For(60*time.Second).
            ToFile("record.csv"),
    )
    defer s.End()

    // do the necessary!
