前面两篇文章已经介绍如何搭建Prometheus和Grafana，本文介绍如何快速监控Spring Boot进程

快速接入

引入Jar包（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>
</dependency>

配置metrics（application.properties）

#Metrics related configurations
management.endpoint.metrics.enabled=true
management.endpoints.web.exposure.include=*
management.endpoint.prometheus.enabled=true
management.metrics.export.prometheus.enabled=true

查看指标 http://localhost:8080/actuator/prometheus

prometheus监控指标

修改Prometheus配置（prometheus.yml）

#Global configurations
global:
  scrape_interval:     5s # Set the scrape interval to every 5 seconds.
  evaluation_interval: 5s # Evaluate rules every 5 seconds.
scrape_configs:
  - job_name: 'spring-boot'
    metrics_path: '/actuator/prometheus'
    static_configs:
      - targets: ['localhost:8080']

重启Prometheus

./perometheus --config.file=prometheus.yml

配置Grafana

配置指标jvm_memory_committed_bytes

再配置更多指标
- jvm_threads_states_threads
- jvm_memory_used_bytes
- process_cpu_usage
- rate(http_server_requests_seconds_sum[5m])
- jvm_gc_pause_seconds_count
