spring maven项目 实时接口请求次数及时间发送到grafana监控_亲测成功

说明: spring项目使用aop方式拿到请求接口uri,算出从请求到响应的耗时, 然后使用statsd包发送udp数据给grafana去展示.

完全不影响代码性能和稳定性,因为使用udp协议发送,就算grafana那边挂了,也不影响项目正常运行

UDP简单介绍

UDP提供不可靠服务

UDP是一个非连接的协议，传输数据之前源端和终端不建立连接， 当它想传送时就简单地去抓取来自应用程序的数据，并尽可能快地把它扔到网络上。 在发送端，UDP传送数据的速度仅仅是受应用程序生成数据的速度、 计算机的能力和传输带宽的限制； 在接收端，UDP把每个消息段放在队列中，应用程序每次从队列中读一个消息段。

maven项目pom.xml引入依赖包

		<dependency><groupId>com.timgroup</groupId><artifactId>java-statsd-client</artifactId><version>3.1.0</version></dependency>    

配置监控udp地址

statsd:prefix: devhost: 192.168.1.53port: 8125

初始化配置

package com.beyond.app.config;import com.timgroup.statsd.NonBlockingStatsDClient;
import com.timgroup.statsd.StatsDClient;
import org.apache.logging.log4j.LogManager;
import org.apache.logging.log4j.Logger;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;@Configuration
public class StatsdConfig {private static final Logger logger = LogManager.getLogger(StatsdConfig.class);@Value("${spring.statsd.prefix}")private String prefix;@Value("${spring.statsd.host}")private String host;@Value("${spring.statsd.port}")private int port;@Bean(name = "statsDClient")public StatsDClient statsDClient() {logger.info("StatsdConfig Configuring Statsd {}-{}:{}", prefix, host, port);return new NonBlockingStatsDClient(prefix, host, port);}}

定义service

package com.beyond.app.service;import com.timgroup.statsd.StatsDClient;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.scheduling.annotation.Async;
import org.springframework.stereotype.Service;/*** Created by liang.*/
@Service
public class StatsdService {@Autowiredprivate StatsDClient statsDClient;@Asyncpublic void statsd (String uri, long time) {statsDClient.time("manage." + uri, time);//dev.manage.uri:10|ms//dev开发环境, manage功能, uri接口, 10ms接口耗时}}
