• 此plugin用于业务的存活检测，比如端口检测portCheck，业务接口检测httpCheck，进程pid重启报警pidCheck
• plugin可以复用，但配置需要按需修改其值
• port有多个端口的，可以用","逗号隔开
• 有多个业务的，配置文件中的section直接使用a ~ z即可，metric可以拿来区分业务
• httpCheck里面，无论是GET还是POST，data这个key对应的value是需要传递的数据，无数据的话，直接写"data="，也就是值为空即可
• uri需要写完整
• 下面的配置仅仅是示范
• 关于返回值：返回值value=1表示正常，value=0表示服务不正常，value=2表示进程重启过
• 按照此规范填写配置即可，保存到配置文件conf.ini
• 其实falcon自带的proc.num和net.port.listen
