【Prometheus】集成spring boot项目

Spring Boot项目配置

• pom文件添加依赖

<dependency>
    <groupId>io.micrometer</groupId>
    <artifactId>micrometer-registry-prometheus</artifactId>
    <version>1.5.1</version>
</dependency>

• application.yml文件添加配置

management:
  endpoints:
    web:
      exposure:
        include: '*'
      base-path: /actuator
  endpoint:
    logfile:
      external-file: ./log/info.log
  metrics:
    export:
      prometheus:
        enabled: true
      jmx:
        enabled: true
    tags:
      application: ${spring.application.name}

• 添加如下配置类

package com.renjia.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;

/**
 * 监控指标配置
 *
 * @author daijiong
 * @version : MethricsConfig.java, v 0.1 2021/3/24 15:13 daijiong Exp $$
 */
@Configuration
public class MetricsConfig {

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

Prometheus配置

• prometheus.yml配置

# spring boot项目名称
- job_name: 'uker-psp-site'
	# 如果spring boot项目有context-path，要添加
    metrics_path: '/uker-psp-site/actuator/prometheus'
    static_configs:
    # spring boot项目访问地址
    - targets: ['172.16.30.180:60005']

• 重启prometheus

systemctl restart prometheus

• 查看prometheus运行状态

systemctl status prometheus

• 查看spring boot项目是否运行正常
