使用metrics统计接口tps
metrics的简单介绍
metrics是一种性能指标工具，有很多开源工具使用之来来作为其性能监控，如Hadoop，Kafka，Spark，JStorm等。
metrics使用最主要有三个东西:
- Metric Registries
- Metrics 度量指标的类型
- Metrics Report 数据展示方案
metricsRegistry
MetricRegistry类是Metrics的核心，它是存放应用中所有metrics的容器。也是我们使用 Metrics 库的起点。
每一个 metric 都有它独一无二的名字，Metrics 中使用句点名字，如 com.example.Queue.size。当你在 com.example.Queue 下有两个 metric 实例，可以指定地更具体：com.example.Queue.requests.size 和 com.example.Queue.response.size 。使用MetricRegistry类，可以非常方便地生成名字。
五种Metrics类型
guages
最简单的度量指标，只有一个简单的返回值，或者叫瞬时状态，例如，我们想衡量一个待处理队列中任务的个数。
Counters
Counter 就是计数器，Counter 只是用 Gauge 封装了 AtomicLong 。
Meters
Meter度量一系列事件发生的速率(rate)，例如TPS。Meters会统计最近1分钟，5分钟，15分钟，还有全部时间的速率。
Histograms
Histogram统计数据的分布情况。比如最小值，最大值，中间值，还有中位数，75百分位, 90百分位, 95百分位, 98百分位, 99百分位, 和 99.9百分位的值(percentiles)。
Timers
Timer其实是 Histogram 和 Meter 的结合， histogram 某部分代码/调用的耗时， meter统计TPS。
怎么使用暂时不给出代码了，先来看看如何统计接口的tps
Metrics Report
metrics提供了丰富的Report，如JMX、Console、CSV、SLF4J以及图形、HTTP等等
统计接口tps
我采取的办法是使用spring的interceptor与Meters ，Report使用的是ConsoleReport，代码如下
package lew.bing.exp.spr;
import com.codahale.metrics.ConsoleReporter;
import com.codahale.metrics.Meter;
import com.codahale.metrics.Metric;
import com.codahale.metrics.MetricRegistry;
import org.springframework.web.servlet.HandlerInterceptor;
import org.springframework.web.servlet.ModelAndView;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.util.HashMap;
import java.util.Map;
import java.util.concurrent.TimeUnit;
/**

*/
public class MetricsInterceptor implements HandlerInterceptor {
private Map<String,Meter> metricMap = new HashMap<>();
private MetricRegistry metrics = new MetricRegistry();
public MetricsInterceptor() {
metricMap.put("/",metrics.meter("/"));
ConsoleReporter reporter = ConsoleReporter.forRegistry(metrics)
.convertRatesTo(TimeUnit.SECONDS)
.convertDurationsTo(TimeUnit.MILLISECONDS)
.build();
reporter.start(1, TimeUnit.SECONDS);// 1s报道一次
}
@Override
public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {
String servletPath = request.getServletPath();
if (metricMap.containsKey(servletPath)) {
metricMap.get(servletPath).mark();// 统计tps
}
return true;
}
@Override
public void postHandle(HttpServletRequest request, HttpServletResponse response, Object handler, ModelAndView modelAndView) throws Exception {
}
@Override
public void afterCompletion(HttpServletRequest request, HttpServletResponse response, Object handler, Exception ex) throws Exception {
// 可以统计失败以及成功次数
}
}

简单的使用metrics统计tps就介绍到这，metrics还有健康检查，可以用来检测连接数据库是否可用等，感兴趣的同学可以多了解了解。
