I need to fetch file from ftp. Last time I checked, logstash didn't have an input plug-in for ftp. So I'll mount the ftp and logstash will read from file.
The real thing is, can I said to logstash "ok read this file, pass it to openssl with this options (decrypt it), then decode it as a json". Is it doable ?
My question is, I think, about chaining filter (but maybe I am wrong)
In advance thanks, Rémi
