搭建 prometheus + grafana + springboot3 监控

下载安装包

下载prometheus：https://github.com/prometheus/prometheus/releases/download/v2.42.0/prometheus-2.42.0.windows-amd64.zip

https://dl.grafana.com/enterprise/release/grafana-enterprise-9.4.1.windows-amd64.zip

SpringBoot配置

导入依赖

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

添加配置

# 暴露 actuator 端点
# 如果配置了拦截器，需要在拦截器中排除 /actuator/**
management:
  endpoints:
    web:
      exposure:
        include: health,info,prometheus,metrics,metrics-requiredMetricName
        exclude:
    # 自定义端点的启用和关闭
    enabled-by-default: true
  endpoint:
    health:
      show-details: ALWAYS
  # 对外暴露tag
  metrics:
    tags:
      application: 修改为你的服务名

添加配置类

@Configuration(proxyBeanMethods = false)
public class MicrometerConfig {

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

}

启动springboot服务，访问actuator接口，例如： http://localhost:8001/cloud-web-01/actuator ，接口返回值如下图所示

Prometheus配置

1、解压prometheus-2.42.0.windows-amd64.zip，修改prometheus.yml

添加如下配置，注意：除了scrape_interval可以不改之外，其他的配置项都要修改为你的微服务

  # 被监控的服务是cloud-web-01
  - job_name: 'cloud-web-01'
    scrape_interval: 15s
    # actuator/prometheus的URI
    metrics_path: '/cloud-web-01/actuator/prometheus'
    static_configs:
      # cloud-web-01的ip和端口
      - targets: ['127.0.0.1:8001']
