Basically if the IP cannot be found in the database, I want to fill the `geoip.city_name`, `geoip.region_name`, and `geoip.country_name` with a custom value like "PRIVATE ADDRESS" or "IP NOT IN DATABASE" or something similar... is this possible?

You cannot do that using the geoip filter, but, if, after being processed by the geoip filter it has a \_geoip\_lookup\_failure tag then you could try

```
if "_geoip_lookup_failure" in [tags] {
    mutate {
        add_field => {
            "[geoip][city_name] => "Here?"
            "[geoip][region_name]" => "West side? East side?"
            "[geoip][country_name]" => "Whatever you want!"
        }
    }
}

```

I'm trying this but Logstash is giving a syntax error and then failing. Can you fix it?

```auto
            if [log][file][path]=="/opt/zimbra/log/audit.log"{
              grok {
                  break_on_match => false
                  match => {
                      "message" => [
                           "cmd=%{WORD:cmd}",
                           "account=(?<account>[^;]*);",
                           "DeviceType=%{WORD:deviceType}",
                           "\[ip=%{IPV4:src-ip}",
                           "oip=%{IPV4:src-ip}",
                           "protocol=%{WORD:protocol}"
                      ]
                  }
              }
              geoip {
                  source => "[src-ip]"
              }
              if "_geoip_lookup_failure" in [tags] {
                 mutate {
                    add_field => {
                        "[geoip][city_name] => "PRIVATE IP"
                        "[geoip][region_name]" => "PRIVATE IP"
                        "[geoip][country_name]" => "PRIVATE IP"
                    }
                 }
              }
           }

```

You are missing the closing quote on the field name.
