Hi there,

you can either remove the unwanted fields, like:

```
filter {
  mutate {
    remove_field => ["[geoip][city_name]", "[geoip][continent_code]" ...]
  }
}

```

or saving the values you're interested in in another field, replace the geoip field with this new one, and then remove the new field like:

```
filter {
  mutate {
    copy => { "[geoip][city_name]" => "[new_geoip][city_name]" }
    copy => { "[geoip][code1]" => "[new_geoip][code1]" }
    copy => { "[new_geoip]" => "[geoip]" }
    remove_field => ["[new_geoip]" ]
  }
}

```

Guess it depends on how many fields you want to keep out of how many they are in total.
