实验六、Spring Boot Actuator监控实验

实验步骤

1. 运行Spring Boot + Actuator

将actuatordemo应用导入Eclipse IDE

Review actuatordemo代码

以Spring Boot方式运行actuatordemo

校验metrics端点

http://localhost:8080/prometheus

2. 配置和运行Promethus

在Prometheus安装目录下

在prometheus.yml 中添加针对wmi-exporter的监控job

  - job_name: 'actuator-demo'
    metrics_path: '/prometheus'
    static_configs:
      - targets: ['localhost:8080']

运行Prometheus

./prometheus.exe

访问Prometheus UI

http://localhost:9090

通过Prometheus->Status的configuration和targets校验配置正确

通过Prometheus->Graph查询actuator-demo在UP=1状态

up{job="actuatordemo"}

3. Grafana Dashboard for JVM (Micrometer)

在Grafana安装目录下启动Grafana服务器

./bin/grafana-server.exe

登录Grafana UI(admin/admin)

http://localhost:3000

通过Grafana的**+**图标导入(Import) JVM (Micrometer) dashboard：

• grafana id = 4701
• 注意选中prometheus数据源

查看JVM (Micormeter) dashboard。

4. 参考
