修改流利的json输出

Question

How can we easily transform with fluentd( and plugins ) something like this

{
    "remote": "87.85.14.126",
    "city": "saint-hubert"
}

To this:

{
   "geoip": {
       "remote": "87.85.14.126",
       "city": "saint-hubert"
   }
}

Thank you

Based on the answer by repeatedly( https://github.com/repeatedly ).

<filter test.**>
  @type record_transformer
  enable_ruby true
  auto_typecast true

  <record>
    geoip ${{"remote" => "${remote}", "city" => "${city}"}}
  </record>
</filter>
