What about reading the man page?
<sigh>
My reply was what I have done, not what I'll now do since I was given some direction so will add the additional logging :).
Logging does not work per levels (256 is not more than 128, it's just something else. Moreover, since many years ago, user-friendly names have been introduced and documented. Use ""stats,acl"if you want both levels.
Took a while to find information on how to enter that into the conf file. Anyhow, I'll test again and see what I get.
