Hi
I've observed that logstash with input plugin doesn't proceed in the correct way gz files in sincedb. I saw that logstash doesn't put all logs info to sincedb but only the header without names. If I have restarted logstash, with start\_position as default "end", he has tried to load the same one files. This mechanize does not handle gz files properly.
