Hi, moving from Logstash 6.3.0 to 6.4.0 with the exact same configuration and log files, I've noticed that the latter is not working. From Logstash logs I can see that the pipeline is starting, but no data is sent in output. Could you please help me understanding what to check? ---

I don't know your previous configuration information, but you can refer to these configurations to test your environment. I'm working properly.
