ipvs模块中无任何配置，查看github文档写了一个有点问题，方便提供一个可用的demo吗？

[[inputs.ipvs]]
  [[inputs.ipvs.virtual_server]]
    address = "xxxxxx"
    port = 8448
    protocol = "tcp"
    sched = "dr"
    address_family = "inet"

    [[inputs.ipvs.real_server]]
      address = "xxxxxx"
      port = 8448

    [[inputs.ipvs.real_server]]
      address = "xxxxxx"
      port = 8448

    [[inputs.ipvs.real_server]]
      address = "xxxxxxx"
      port = 8448

这是我按照官网文档写的，但是有问题。希望大佬可以提供一个可用的，谢谢
