2. start

2.1 直接使用上面的工具（我修改好了的）

2.2 启动 jar

## 让 jmx_exporter 跟 jar 实例一起启动 注意端口（jmx_prometheus_javaagent-0.13.0.jar=30015）
## 多个jar都在用的情况要使用不同的端口
nohup java -javaagent:/doc/program/eco/jmx_prometheus_javaagent-0.13.0.jar=30015:/doc/program/eco/jar_config.yaml -Dfile.encoding=utf-8 -Dspring.profiles.active=prod -Xms256m -Xmx512m -jar  /doc/program/eco/eco.war > /dev/null 2>&1 &

3. 配置 prometheus.yaml 后重启prometheus

  - job_name: 'eco'
    scrape_interval: 10s
    static_configs:
    - targets: ['localhost:30015']
      labels:
        instance: eco

4. 配置图例（不要按照上面参考文件的修改图例配置）
