Grafana和Prometheus监控SpringBoot项目

本文章记录Grafana和Prometheus搭建过程，以及如何监控SpringBoot项目指标。

1. Prometheus：一个开源系统监控和警报工具包。
2. Grafana：Go语言开发的开源数据可视化工具，可以做数据监控和数据统计，带有告警功能。
3. Micrometer：收集Java性能数据

SpringBoot集成Micrometer

首先，要想我们的SpringBoot可以被监控，首先要暴露监控指标接口。

Pom文件引入依赖

<!-- prometheus相关 -->
<!-- micrometer:收集Java性能数据 -->
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-actuator</artifactId>
</dependency>
<dependency>
    <groupId>io.micrometer</groupId>
    <artifactId>micrometer-registry-prometheus</artifactId>
</dependency>

yml配置文件暴露监控端点

server:
  port: 9000

spring:
  application:
    name: prometheus-monitor

management:
  endpoints:
    web:
      # 暴露监控端点
      # 指定所有的web接口都会上报
      exposure:
        include: '*'
  # 这个应用所有上报的 metrics 都会带上 application 这个标签
  metrics:
    tags:
      application: ${spring.application.name}
###################上面配置完毕之后，会提供一个 /actuator/prometheus 的端点，供prometheus来拉取Metrics信息###################

编写配置类，注册监控配置

package com.itjing.monitor.config;

import io.micrometer.core.instrument.MeterRegistry;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.boot.actuate.autoconfigure.metrics.MeterRegistryCustomizer;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

/**
 * @Description: Java性能数据收集配置类
 * @Author: 公众号：程序员阿晶
 * @CreateTime: 2023-02-23 09:39
 */
@Configuration
public class MicrometerConfig {

    @Bean
    public MeterRegistryCustomizer<MeterRegistry> meterRegistryCustomizer(
            @Value("${spring.application.name}") String applicationName) {
        // 注册监控配置
        // 这是比较核心的注册模块
        return (registry) -> registry.config().commonTags("application", applicationName);
    }
}

启动应用，访问

http://127.0.0.1:9000/actuator/prometheus

部署Grafana和Prometheus

本次部署使用docker-compose进行容器编排

编写docker-compose编排文件

docker-compose-prometheus.yml

下面的grafana中的mysql配置信息，在实际使用的时候，可能并不是在这里启动的，可能有一个公共的数据库，这时只需要将下面grafana中的mysql配置信息改为相应的即可，记得建对应的数据库

在编排文件中，由于需要挂载prometheus.yml文件，可以事先在宿主机上配置好，需要挂载的配置文件信息

# 定义清除过期日志的时间(这里设置为7天)

# TIMESTAMP如果没有显示声明NOT NULL，允许NULL值
explicit_defaults_for_timestamp = true

# 它控制着mysqld进程能使用的最大文件描述(FD)符数量。
# 需要注意的是这个变量的值并不一定是你设定的值，mysqld会在系统允许的情况下尽量获取更多的FD数量
