When set 'sincedb_path' to '/dev/null' and 'start_position' to 'beginning', logstash does not parse files as expected, it always start and hangs at output below:
Settings: Default pipeline workers: 4
Pipeline main started
in my case, I have a lot of existing logs, but I do not want logstash to monitoring the logs, I just want the logs to be parsed and sent to elastic search and be done with them. In addition, the logs are stored in a external hard drive formatted with NTFS filesystem mounted to Ubuntu.
