ubuntu20.04系统中springboot集成prometheus和grafana

pom.xml 注意依赖引入版本，避免冲突

<dependency>
	 <groupId>org.springframework.boot</groupId>
	 <artifactId>spring-boot-starter-web</artifactId>
</dependency>
<dependency>
		<groupId>org.springframework.boot</groupId>
		<artifactId>spring-boot-starter-actuator</artifactId>
</dependency>
<dependency>
		<groupId>io.micrometer</groupId>
		<artifactId>micrometer-registry-prometheus</artifactId>
</dependency>

application-dev.yml

spring:
  application:
    name: springboot  #项目名
management:
  endpoints:
    web:
      exposure:
        include: 'prometheus'
  metrics:
    tags:
      application: $spring.application.name

启动项目，访问 http://localhost:8080/actuator/prometheus
如果下载这样的文件，那就没问题了：

开始下载安装 prometheus
下载地址：https://prometheus.io/download/
sudo tar zxvf prometheus-2.31.1.linux-amd64.tar.gz
修改配置文件：sudo vim prometheus.yml

global:
  scrape_interval:     15s # By default, scrape targets every 15 seconds.
  # Attach these labels to any time series or alerts when communicating with
  # external systems (federation, remote storage, Alertmanager).
  external_labels:
    monitor: 'codelab-monitor'
# A scrape configuration containing exactly one endpoint to scrape:
# Here it's Prometheus itself.
scrape_configs:
  # The job name is added as a label `job=<job_name>` to any timeseries scraped from this config.
  - job_name: 'prometheus'
    # Override the global default and scrape targets from this job every 5 seconds.
    scrape_interval: 5s
    static_configs:
      - targets: ['localhost:9090']
  - job_name: 'springboot'
    scrape_interval: 5s
    metrics_path: '/actuator/prometheus'
    static_configs:
      - targets: ['127.0.0.1:8080']

启动 sudo ./prometheus --config.file=prometheus.yml

Prometheus———Linux系统安装，配置后台启动方式
https://blog.csdn.net/qq_32415063/article/details/105607008

启动类：

@Bean
MeterRegistryCustomizer<MeterRegistry> configurer(@Value("$spring.application.name") String applicationName) 
    return (registry) -> registry.config().commonTags("application", applicationName);

项目中写了两个测试方法
请求执行接口(多请求几次)
http://localhost:8080/test

package com.example.controller;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

/**
 * @ClassName PrometheusTestController
 * @Description springboot集成普罗米修斯(Prometheus)的方法
 * @Author 
 * @Date 2021/11/15 上午10:17
 */
@RestController
public class PrometheusTestController 

    Logger logger = LoggerFactory.getLogger(PrometheusTestController.class);

    @GetMapping("/test")
    public String test() 
        logger.info("test");
        return "ok";
    

    @GetMapping("")
    public String home() 
        logger.info("home");
        return "ok";
