springboot2.X整合prometheus监控的实例讲解

springboot2.x暴露健康状况通过prometheus监控

加入依赖

 <!--prometheus监控 https://prometheus.io/docs/introduction/overview/-->
 <dependency>
 <groupId>org.springframework.boot</groupId>
 <artifactId>spring-boot-starter-actuator</artifactId>
 </dependency>
 <dependency>

 <!--prometheus监控 https://prometheus.io/docs/introduction/overview/-->

application.yml加入相关配置

 #prometheus+grafana+springboot2监控集成配置

主启动类加入配置

package com.drore.saas;
import com.drore.saas.services.service.StorageService;
import io.micrometer.core.instrument.MeterRegistry;
import org.springframework.boot.CommandLineRunner;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.actuate.autoconfigure.metrics.MeterRegistryCustomizer;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.web.servlet.ServletComponentScan;
import org.springframework.context.annotation.Bean;
@SpringBootApplication
@ServletComponentScan
public class TenantappApplication {
 public static void main(String[] args) {
 SpringApplication.run(TenantappApplication.class, args);
 }
 @Bean
 CommandLineRunner init(StorageService storageService) {
 return (args) -> {
 storageService.init();
 };
 }
#prometheus+grafana+springboot2监控集成配置
 @Bean
 MeterRegistryCustomizer meterRegistryCustomizer(MeterRegistry meterRegistry) {
 return meterRegistry1 -> {
 meterRegistry.config()
 .commonTags("application", "Tenantapp");
 };
 }
 #prometheus+grafana+springboot2监控集成配置
}

启动之后通过路径访问查看健康状况

http://xxxxxx/metrics/prometheus

查看到的数据如下：
