搭建SpringBoot+Prometheus+Grafana自动监控平台

promitheus作用：

   它是一个开源的专门做系统监控和系统报警的软件，加入了CNCF基金会，而上一个加入基金会的是Kubernates，支持多种exporter采集指标数据，还支持PushGateway进行数据上报，Promethus性能足够支持上万台规模的集群。

Grafana是一个跨平台的开源的度量分析和可视化工具，可以通过将采集的指标数据查询然后可视化的展示。

指标监控（Monitoring）：Linux占用内存，CPU负载占用率，磁盘IO输入输出，线程数量

链路追踪（Tracing）：业务相关，多系统完成业务处理

日志收集（Logging）：集成ELK，方便查看日志信息

Springboot部分：

pom.xml

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

application.yml

spring:
  application:
    name: springboot-prometheus

management:
  endpoint:
    prometheus:
      enabled: true
    health:
      show-details: always
  metrics:
    export:
      prometheus:
        enabled: true
  endpoints:
    web:
      exposure:
        include: "*"

自动装载：

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

服务器部分
