Is there a way to log actual upstream server IP address ? There is a variable "$proxy_host", but it logs "upstream" section name instead of the actual IP address.

edit: I forgot to add. I know, there is "$upstream_addr" variable, but it contains ALL the upstream servers that were checked for the page. And I only need one that has actually returned the page. I do not need those with "HTTP404" response.
