I have an input file named test.csv and I use it as some kind of configuration. How do i force logstash to re read the file from beginning, everytime there is modification in the test.csv file

Maybe you could delete the old copy of the file and recreate the new?

Yeah, there's no way to do this unless you restart LS and then set sincedb to `/dev/null` or similar.

Thanks for the replies.  
Yes, there is no way. Even deleting file and recreating them didn't help, as the inode number doesnt get changed always and file input plugin keeps track of file size using inodes
