Logging access to SMB shared files (date, time, username, filename)

Hi

Is there any extension / settings to enable SMB log for just this short information: date, time, username, filename ?
I would like to know who and when accessing the files (for audit / development / security purposes).

I know there is an audit option and this is possible to play with extraoptions for SMB:

full_audit:prefix = %u|%I|%S
full_audit:success = open, opendir, read, write
full_audit:failure = none
full_audit:facility = local7
full_audit:priority = NOTICE

Then in the last line of file:

sudo nano /etc/rsyslog.conf

add

local7.*    /var/log/samba-audit.log

and then

sudo systemctl restart rsyslog

And so one, but then inside /var/log/samba-audit.log there is too much and too detailed informations, so it takes a lot of disk space and dhis is difficult to find exact inforrmation,.

I would like to have a simple where eah next line including only date, time, username, filename.

How to solve and introduce it in OMV environment ?

Thank you and best regards
