This may help:

Any variable in the custom log format - ie. $server_name, $host, etc does not log the Host headers, but rather the server name string set with the server_name directive (if matched). This makes it impossible to have a combined log file for different sites set in a virtual hosting environment on the same IP address.

$http_host.
