Try `sincedb_path => "NUL"`

If logstash successfully writes the contents of the file to elasticsearch then you should expect to see exactly what you get in the logstash log. It may be working.

You could try [setting](https://discuss.elastic.co/t/logstash-when-started-using-nohup-it-is-logging-too-much-resulting-in-huge-size/276560/2) TRACE level logging and see [what filewatch has to say](https://discuss.elastic.co/t/logstash-wildcards-regex-not-working/164204/2).
