springBoot1.X或2.X整合prometheus配置

1、首先需要引入依赖：

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-actuator</artifactId>
    <version>1.5.4.RELEASE</version>
</dependency>
<dependency>
    <groupId>io.micrometer</groupId>
    <artifactId>micrometer-registry-prometheus</artifactId>
    <version>1.0.3</version>
</dependency>
<dependency>
    <groupId>io.micrometer</groupId>
    <artifactId>micrometer-spring-legacy</artifactId>
    <version>1.0.3</version>
</dependency>
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-security</artifactId>
</dependency>

spring-boot-starter-security依赖是为了开启对监控数据获取接口（我这里是/prometheus）进行用户名密码校验的，如果没有这个校验我们的监控接口相当于在裸奔。任何人都可以通过这个接口获取我们的监控数据

 

• 2、添加一个配置类，使prometheus知道我们当前项目的名称以及其他信息

  @Configuration
  public class MicrometerConfiguration {
      @Bean
      MeterRegistryCustomizer meterRegistryCustomizer(MeterRegistry meterRegistry) {
          return meterRegistry1 -> {
              meterRegistry.config()
                      .commonTags("application", "micrometer-gateway");
          };
      }
  }

  3、配置application.properties

  #开启安全验证
  management.security.enabled=true
  #监控地址接口，这里可以和项目端口区分开
  management.port=20028
  #监控地址前缀
  management.context-path=/monitor
  management.endpoints.web.exposure.include=*
  management.endpoints.jmx.exposure.include=*
  management.endpoints.shutdown.exposure.include=*
  management.metrics.distribution.percentiles-histogram[http.server.requests]=true
  
  #这是spring-boot-starter-security对应的basic_auth验证开启
  security.basic.enabled=true
  #对哪些地址开启校验
  security.basic.path=/monitor
  security.user.name=admin
  security.user.password=admin
