How to add logstash gork filter and field

Hi @magnusbaeck

Thanks.

I have another problems with my filebeat.yml

when I start my "sudo ./filebeat -e -c filebeat-logstash.yml -d "publish", I always got the following error.

anb041:filebeat-1.3.1 mmlug$ sudo ./filebeat -e -c filebeat-logstash.yml -d "publish"
