Hi guys, i want to ask how to create new fields from metricbeat value like host.network.in.bytes for network monitoring.  
i want to create query PPL from metricbeat value but the value is null, i think because the value from host.network.in.bytes is not readable, so im trying to create new fields NetworkInbound for host.network.in.bytes but the value isn't appear.

```auto
input {
  beats {
    port => 5044
  }
}

filter {
      mutate {
        add_fields=> {"NetworkInbound" => "host.network.in.bytes"}
      }
    }

output {
  elasticsearch{
    hosts => ["100.100.100.100:9200"]
    index => "metricbeat"

```

after use this metricbeat.conf the value from NetworkInbound only "host.network.in.byes" string not the value like this

 ![createfields](https://us1.discourse-cdn.com/elastic/original/3X/b/6/b6576e443ce759b078dcb5d0d7862951b64d821e.png)

my question is : How to create new fields for host.network.in.bytes, host.network.out.bytes for monitoring network so the TOP 5 VALUES will be appear ?

should i use add\_fields at processor metricbeat like this ? or maybe you have an advice for me

```auto
processors:
  - add_fields:
      target: project
      fields:
        name: myproject
        id: '574734885120952459'

```
