配置

这个是在 安装了 process-exporter的机器上
Process-Exporter的做法是配置需要监控的进程的名称，他会去搜索该进程从而得到其需要的监控信息， 其实也就是我们常做的“ps -efl | grep xxx”命令来查看对应的进程。配置文件一开始是不存在的，需要我们创建，名字可以自定义：


这个配置是在 prometheus机器上
现在，我们需要去配置Prometheus来采集这份数据了，和其他配置一样，就是给Prometheus添加一份数据源：
  - job_name: 'snsweb2-process'
    static_configs:
    - targets: ['12.41.11.20:9256']
