Hi,
I would like to send log files using filebeat directly to elasticsearch but lines in log file are in custom string format and I would like preprocess those lines using grok or something?
I cannot seem to find any example, how to configure filebeat.yml to use regex, grok to send log files directly to elasticsearch; is out there any example?
My log file lines look like:
[28-Apr-2020 14:01:58 +0000]: <nht5271m> Successful login for username1 (ID: 1) from 111.222.333.444 in session nht5271mokfeqd1i
Kind regards,
Rok
