Windows server 2003 and Elastic agent


I know Windows server 2003 logs is not supported. But is it possible to solve?

I use a powershell script to collect Windows server 2003 logs to a Windows server 2022 then Im using Elastic Agent with a custom logs integrestion to collect logs from a path.

The problem is the filestructure. It's seperating the logs after " : "

Example below, instead of having 1 log file, i end up having 14 logfiles. Could it be a possible to use grok and send it to logstash, and if so.. how should i grok it?
