Auditbeat-oss - system module

Hello everyone,

I would like to use some features available in the system module of auditbeat:

Unfortunately this modules is not available in the auditbeat-oss but only in auditbeat

Also an other issue is the fact than the last usable version of auditbeat-oss with OpenSearch is the version 7.12.1, so all the new features and fix from this version to version 8.4.2 are not available.

Is anybody have a fix for that or a way to backport that feature or an others way to make it work with OpenSearch ?
And is any plan ongoing to add support of news version of Beats OSS ?

Thanks a lot and Cheers,
