本案例使用Prometheus去追踪SpringBoot的Metrics信息，通过Grafana将Prometheus收集到的信息进行可视化展示。
使用的软件版本：
OS：Win10 x64 专业版
JDK1.8_181
Prometheus-2.0
Grafana-6.3.0
1.Prometheus 配置文件 如下所示
# my global config global: scrape_interval: 15s # Set the scrape interval to every 15 seconds. Default is every 1 minute. # 抓取target的时间间隔 evaluation_interval: 15s # Evaluate rules every 15 seconds. The default is every 1 minute. # 计算rules 的时间间隔 # scrape_timeout is set to the global default (10s). # 抓取的超时时间 # Alertmanager configuration alerting: alertmanagers: - static_configs: - targets: # - alertmanager:9093 # Load rules once and periodically evaluate them according to the global 'evaluation_interval'. rule_files: # - "first_rules.yml" # - "second_rules.yml" # A scrape configuration containing exactly one endpoint to scrape: # Here it's Prometheus itself. scrape_configs: - job_name: 'jvm-web' scrape_interval: 5s scrape_timeout: 5s metrics_path: '/actuator/prometheus' scheme: http static_configs: - targets: - 127.0.0.1:8389 #此处填写 Spring Boot 应用的 IP + 端口号2.创建一个Spring Boot程序，这里只放pom.xml中主要配置
