And, you still see the non-healthcheck, normal traffic logged using the X-Forwarded-For information?

Yes. Do exactly the same myself with a simple !aclname at the end of access_log directives. I can't figure out why neither that nor the longer log_access is working for you.

Nothing coming from the load balancers is being logged (even requests using X-Forwarded-For).
