Keep only certain line


(bus) #1

Hello,

I use filebeat to send files to logstash and then logstash parse them.

During the parse, is it possible to do :

if [number_line != "3" ]
{
  drop { }
}

To keep only the line 3 of the file ?

Thx you

No. Filebeat doesn't track the line number, only the file offset.
