Very strange thing is happening.  
Logstash is being launched with the following command:

logstash -f /tmp/my\_config.yml  
sincedb\_path -\> set to /dev/null

Input file is being generated- nothing happens.  
Input file is being modified- nothing happens  
I manually modify file- nothing happens

BUT, when I press CTRL+C I get the following info:

observingtail - QUIT 0 closing all files and shutting down.  
[...]  
file - Opening file {:path =\> "/tmp/input.json.log"} . \<-- this is my log file defined in the YML..  
aaaand then the data is being read and saved to the ES node....

Any ideas?

Fixed. Resolved as a part of another issue: [The shutdown process appears to be stalled due to busy or blocked plugins](https://discuss.elastic.co/t/the-shutdown-process-appears-to-be-stalled-due-to-busy-or-blocked-plugins/154257)
