SpringBoot+Prometheus+Grafana 监控面板
提示：本文使用SpringBoot 简单样例，介绍基础配置和使用方法
包含内容：Docker、SpringBoot、Maven、 Prometheus、Grafana等
提示：本文包含官网内容介绍，具体更项目的学习，请参照各官网文档，谢谢
前言
Prometheus
官网：https://prometheus.io/文档地址：https://prometheus.io/docs/introduction/overview/
使用领先的开源监控解决方案为您的指标和警报提供支持。
Prometheus是一个开源系统监控和警报工具包，最初是在 SoundCloud构建的。自2012年推出以来，许多公司和组织都采用了Prometheus，该项目拥有非常活跃的开发者和用户社区。它现在是一个独立的开源项目，独立于任何公司进行维护。为了强调这一点，并明确项目的治理结构，Prometheus 于 2016 年加入 云原生计算基金会，成为继Kubernetes之后的第二个托管项目。
Prometheus 将其指标收集并存储为时间序列数据，即指标信息与记录时的时间戳一起存储，以及称为标签的可选键值对。
grafana
官网地址：https://grafana.com/文档地址：https://grafana.com/docs/grafana/latest/
grafana是一个非常酷的数据可视化平台，常常应用于显示监控数据，底层数据源可以支持influxDb、graphite、elasticSeach
一、创建SpringBoot项目
创建普通SpringBoot项目

二、安装Docker（Centos）
1.引入库
代码如下（示例）：
import numpy as np
import pandas as pd
import matplotlib.pyplot as plt
import seaborn as sns
import warnings
warnings.filterwarnings('ignore')
import ssl
ssl._create_default_https_context = ssl._create_unverified_context
application.yml
server:
port: 8088
spring:
application:
name: demo
management:
endpoints:
web:
exposure:
include: '*'
# include: prometheus
# base-path: /
metrics:
tags:
application: ${spring.application.name}
AspectAop.java
package org.example.aop;
import io.micrometer.core.instrument.Counter;
import io.micrometer.core.instrument.MeterRegistry;
import org.aspectj.lang.JoinPoint;
import org.aspectj.lang.annotation.AfterReturning;
import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Before;
import org.aspectj.lang.annotation.Pointcut;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;
import javax.annotation.PostConstruct;
@Component
@Aspect
public class AspectAop {
@Autowired
MeterRegistry registry;
private Counter counter_total;
ThreadLocal<Long> startTime = new ThreadLocal<>();
@Pointcut("execution(public * controller.*.*(..))")
private void pointCut(){}
@PostConstruct
public void init(){
counter_total = registry.counter("app_requests_count", "v1", "core");
}
@Before("pointCut()")
public void doBefore(JoinPoint joinPoint)throws Throwable {
startTime.set(System.currentTimeMillis());
counter_total.increment();
}
@AfterReturning(returning = "returnVal", pointcut = "pointCut()")
public void doAftereReturning(Object returnVal){
System.out.println("请求执行时间：" + (System.currentTimeMillis() - startTime.get()));
}
}
接口控制器
GreetingController.java
package org.example.controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;
@RestController
public class GreetingController {
@RequestMapping("/greeting")
public String test(@RequestParam(value="name", defaultValue="test") String name) {
return name;
}
}
接口请求类
IndexController.java
package org.example.controller;
import io.micrometer.core.instrument.Counter;
import io.micrometer.core.instrument.MeterRegistry;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import javax.annotation.PostConstruct;
import java.util.Random;
import java.util.concurrent.atomic.AtomicInteger;
@RestController
@RequestMapping("/v1")
public class IndexController {
@Autowired
MeterRegistry registry;
private Counter counter_core;
private Counter counter_index;
private AtomicInteger app_online_count;
@PostConstruct
private void init(){
counter_core = registry.counter("app_requests_method_count", "method", "IndexController.core");
counter_index = registry.counter("app_requests_method_count", "method", "IndexController.index");
app_online_count = registry.gauge("app_online_count", new AtomicInteger(0));
}
@RequestMapping(value = "/index")
public Object index(){
try{
counter_index.increment();
} catch (Exception e) {
return e;
}
return counter_index.count() + " index of springboot2-prometheus.";
}
@RequestMapping(value = "/core")
public Object coreUrl(){
try{
counter_core.increment();
} catch (Exception e) {
return e;
}
return counter_core.count() + " coreUrl Monitor by Prometheus.";
}
@RequestMapping(value = "/online")
public Object onlineCount(){
int people = 0;
try {
people = new Random().nextInt(2000);
app_online_count.set(people);
} catch (Exception e){
return e;
}
return "current online people: " + people;
}
}
主方法
Main.java
package org.example;
import io.micrometer.core.instrument.MeterRegistry;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.actuate.autoconfigure.metrics.MeterRegistryCustomizer;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.Bean;
@SpringBootApplication
public class Main {
public static void main(String[] args) {
System.out.println("Hello world!");
SpringApplication.run(Main.class, args);
System.out.println("start successFully");
}
@Bean
MeterRegistryCustomizer<MeterRegistry> configurer(@Value("${spring.application.name}") String applicationName){
return registry -> registry.config().commonTags("application", applicationName);
}
}

验证成功后，将文件进行打包，并发布，如果在本地安装，则后续配置的项目地址为本地
三、安装Docker
Centos8.2
安装
yum install docker -y
启动
systemctl start docker
开机启动
systemctl enable docker
检查是否安装成功
docker --version
检查返回示例
Emulate Docker CLI using podman. Create /etc/containers/nodocker to quiet msg.
podman version 4.5.1
四、安装Prometheus(Docker)
编写配置文件
prometheus.yml
scrape_configs:
# 指定当前任务的名称
- job_name: 'spring'
# 采集数据间隔时间
scrape_interval: 15s
# 采集超时时间
scrape_timeout: 180s
# 采集接口路径
metrics_path: '/actuator/prometheus'
# 采集服务的地址，SpringBoot项目的地址
static_configs:
- targets: ['103.228.171.244:8088', '156.224.25.128:8088']
拉镜像，根据指定的外部配置文件，创建容器并启动
docker run -d -p 9090:9090 -v /buss/prometheus.yml:/etc/prometheus/prometheus.yml --name prometheus prom/prometheus:latest --log.level=debug --storage.tsdb.retention.time=3d --config.file=/etc/prometheus/prometheus.yml
这里拉取时，可能存在多个镜像源地址，当前博主选择的是官网的源地址
如果容器启动，则请求地址
http://103.228.171.244:9090/
请求返回页面示例
五、安装Grafana(Docker)
拉取Grafana镜像
docker pull grafana/grafana
创建容器并启动容器
docker run -d -p 3000:3000 grafana/grafana
如果启动成功，访问页面
http://103.228.171.244:3000/
默认用户名密码
admin
admin
页面示例
如果不成功，查看日志
tail logs -f 容器ID
如果存在问题，可以先删除容器，重新创建并启动
docker rm 容器ID
六、配置和运行测试
点击面板
使用模板引入
输入模板编号4701引入，然后保存模板地址：https://grafana.com/grafana/dashboards/
然后点击标签，回到面板出，点击对应保存的模板
查看效果示例
