I have tested your .conf, it looks OK.

Check the /var/log/logstash/logstash-plain.log file, there should be more info.

here is the info from logstash-plain.log file:

That is only -t, test/validation .conf file. Should be more. If there is no newer records, change ownership to "logstash" user for /var/log/logstash/ and files.
