Log uploaded/downloaded files

is it possible logging every uploaded and downloaded file (name, type, size, who uploaded it and who downloaded it)

If it is directly via webdav (everything except through the web-interface), it shows the user name in the webserver-logfiles.
You can use the activity app to show certain events of your folders (only based on your own files). Not sure, if there are perhaps more apps ÔÇŽ

Wir nutzen ausschlie├člich das Webinterface und ich suche einen weg alle Daten zu loggen von jedem benutzer. Vor allem benutze ich die Gruppenordner

Please do not mix English and German. For German there is another category.

sry forgot it we only use the webinterface is there a way every traffic from and to the nextcloud to log?
