HI Folks,
What is exactly ignore_older. I have hourly log files on my server where filebeat is running and streaming logs to logstash.
I have ignore_older set to 30m. I stopped logstash process on destination at 12 10PM today adn started it back at 4 10 PM. In the mean time on the filebeat client, 12, 13 , 14, 15 , 16 Hr log files got created. However filebeats was running on the servers(sources).
After starting logstash at 4:10 I thought 12, 13,14,15 hr log files will be lost since it is older than ignore_older time which is set to 30m. But to my wonder, I see 12,13,14,15,16 log files getting streamed fully after starting the log stash back.
Can someone pls expalin me exactly abt ignore_older and also provide some good documentation.
Thanks,
karthik.
