I can't tell where to find documentation for relayd's log. But - to be honest - I found it was not too hard to work with. For playing with relayd and httpd I suggest Michael W Lucas's book "Relayd and Httpd Mastery". Mr. Lucas, has a way of writing that is easy to read! https://mwl.io/nonfiction/tools#relayd ...and of course the excellent manpages relayd(8), relayd.conf(5)
