本文详细介绍了如何在SpringBoot应用中配置Prometheus监控，并通过Grafana展示监控数据。首先，通过引入相关依赖并配置Actuator以启用监控接口。接着，配置Prometheus的`prometheus.yml`文件，添加新的监控目标。然后，启动Grafana并展示监控面板。此外，文章还深入解析了HikariCP数据库连接池的监控指标，包括连接数、活跃连接、空闲连接等，帮助理解数据库连接池的运行状态。

一、SpringBoot配置.

①、引入依赖

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

②、开启监控

management:
  endpoints:
    web:
      exposure:
        include: prometheus

③、启动服务,查看监控采集:

http://test.code.com/skywalk/actuator/prometheus

二、定义Prometheus监控任务.

①、prometheus.yml

scrape_configs:
  # The job name is added as a label `job=<job_name>` to any timeseries scraped from this config.
  - job_name: "prometheus"

    # metrics_path defaults to '/metrics'
    # scheme defaults to 'http'.

    static_configs:
      - targets: ["localhost:9090"]
  - job_name: 'Windows'
    static_configs:
    - targets: ['192.168.1.6:9182']
      labels:
        instance: Windows
  # 新添加的采集目标
  - job_name: "skywalk-boot"
    metrics_path: '/skywalk/actuator/prometheus'
    static_configs:
      - targets: ["192.168.1.6:80"]

②、启动prometheus
