Prometheus接入（四、Spring Boot接入）

环境

CentOS 7.9 + Spring Boot 2.6.8

安装

1、依赖引入

        <!-- 预设监控 -->
        <dependency>
            <groupId>io.micrometer</groupId>
            <artifactId>micrometer-registry-prometheus</artifactId>
        </dependency>
        <!--健康监控-->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-actuator</artifactId>
        </dependency>

2、配置文件

management:
  endpoints:
    web:
      base-path: "/status"       ## 自定义暴露地址
      exposure:
        include: "*"
  server:
    port: 12012                  ## 自定义暴露端口
  metrics:
    tags:
      application: ${spring.application.name}
  security:
    enabled: false

4、在Application.java中添加

    /**
     * 应用名称
     */
    @Value("${spring.application.name}")
    private String application;

    @Bean
    MeterRegistryCustomizer<MeterRegistry> configurer() {
        return (registry -> registry.config().commonTags("MyApplication", application));
    }

5、启动查看指标
