Welcome @111387!

The Filebeat Suricata module parses Suricata logs, which are mapped to events modeled by the Elastic Common Schema (ECS). This blog post explains how ECS works, and why it exists.

It sounds like this might be the documentation you're looking for, if, to quote the linked documentation:

you want to use Logstash to perform additional processing on the data collected by Filebeat

Would you be willing to let us know if that helps?
