geoip vai depender de quais informações você utilizará para análise.

This is great but does anyone know how to remove the double quotes out of the output? I'm trying with grok's mutate options but not having much luck

Hi,

If you mean remove in ES, use this -

trim_value => """

For example -

            kv {
                    source => "kvmessage"
                    trim_value => "\""
                    remove_field => [ "kvmessage" ]
                    remove_field => [ "message" ]
            }
