Hello, I have set up the Filebeat to send logs to Logstash. How can I make it send older logs that had not been parsed, to Logstash? Will the logs that have been parsed up to now be duplicated?  
Can I specify a period of time for old logs in order to avoid duplication of the existing logs?  
Can someone explain it to me? Thanks in advance!
