当找到Hbase时间戳时，我们说处理了一个请求。（上面的输出中有5个）

（总开始时间/请求数量）将给出平均吞吐量但是我想写一个java代码，它会找出每分钟处理的请求数（每分钟点击数），因为我想创建一个吞吐量图。

即使我可以通过任何工具实现这一点，它也会很棒有人可以帮帮我吗？

正如其中一条评论中所提到的，最好找一个类似这样的工具，然而，制作一个非常简单的版本并不是那么复杂，但你需要考虑一些像漂移这样的问题，以便让它成为现实。

public static void main (String[] args) {
    ThroughputService t = new ThroughputService();

    CountDownLatch latch = new CountDownLatch(1);

    ScheduledExecutorService service = Executors.newSingleThreadScheduledExecutor();
    service.scheduleAtFixedRate(t, 0, 1, TimeUnit.MINUTES);

    try {
        latch.await();
    } catch (InterruptedException ex) {
        Logger.getLogger(NewClass.class.getName()).log(Level.SEVERE, null, ex);
    }

}

static class ThroughputService implements Runnable {

    @Override
    public void run() {
        //code for calculating your throughput
    }

}

java中每分钟的请求数
