HI all,

I've just started using the below codec

[https://www.elastic.co/guide/en/logstash/current/plugins-codecs-sflow.html](https://www.elastic.co/guide/en/logstash/current/plugins-codecs-sflow.html)

It works well, however doing a straight export into elasticsearch finds 95% of all the fields being of type text

```
root@elk-5:/var/log/logstash# dpkg-query -l | egrep -i "logstash|elastic|kibana" | awk '{ print $2,"\t",$3,"\t",$4}'
elasticsearch 5.1.1 all
kibana 5.1.1 amd64
logstash 1:5.1.1-1 all
root@elk-5:/var/log/logstash#

```

Current logstash config is super basic

```
input {
        udp {
                port => 6343
                codec => sflow {}
        }
}

output {
        elasticsearch {
                hosts => ["172.16.0.46:9200"]
        }
}

```

**I'm wanting to know if someone can give me some help on where to start with a template (json) override to be used on the logstash ES export**

Regards, Daniel
