Nextcloud Server logging / user audit and usage report

Hi, is there a way or the possibility to monitor the NC server in case of what are the users doing and what files are download from whom?
IĀ“d like to know, what files the users are uploading, what they are sharing via public links and what users / ip addresses are downloading this shared files.

I need something similar to the activity feed, the administrator can see after logging in.
Worst case would be to analyze the plain logfiles. For the download I would look after the apache2 logs. Does nextcloud have a log for the other wanted informations?

I already tryed the ā€œUser usage reportā€ app but the output of the app does not include the wanted informations and is way to complicated to work with.

Thx

Kind regards
