Good morning

I would like to know how I can control the data that is sent by netflow to filebeat-kibana, since it generates many documents per minute, I want to know if I can configure the data sampling and only send me data every 5 minutes to not overpass the capacity of the virtual disk, thank you for your help please.

in less than 5 minutes there were such documents so I need you to stop sending me too much data.

on the other hand netflow generates a lot of unnecessary fields that are blank, so I need also how to delete them.

Thank you very much, I look forward to hearing from you soon.
