Full record url in nginx log

We use following nginx site configure file in our production env.

log_format main '$http_x_forwarded_for - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" $request_time';






server {
root /srv/www/web;
server_name *.test.com;
access_log /var/log/nginx/xxx.test.com.access.log main;

Both "http://a.test.com/ping" and "http://b.test.com/ping" http request will be record in file xxx.test.com.access.log.

But there is a problem, nginx don't store "domain name" in xxx.test.com.access.log.

"http://a.test.com/ping" and "http://b.test.com/ping" share the same request "Get /ping".

How can I record "a.test.com" or "b.test.com" in nginx log?

最佳答案

Try adding the $host variable in log_format:

log_format main '$http_x_forwarded_for - $remote_user [$time_local] "$host" "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" $request_time';

http://wiki.nginx.org/HttpCoreModule#.24host:

$host

This variable is equal to line Host in the header of request or name of the server processing the request if the Host header is not available.

This variable may have a different value from $http_host in such cases: 1) when the Host input header is absent or has an empty value, $host equals to the value of server_name directive; 2) when the value of Host contains port number, $host doesn't include that port number. $host's value is always lowercase since 0.8.17.

log_format main '$http_x_forwarded_for - $remote_user [$time_local] ' '"$request_method $scheme://$host$request_uri $server_protocol" ' '$status $body_bytes_sent "$http_referer" ' '"$http_user_agent" $request_time';
