Nginx 记录请求分发日志

奥尔覅几22

　　在nginx接收到请求之后, 需把请求分发到后端WEB服务集群.
　　在这里需要记录分发日志, 来分析后端每台WEB服务器处理的请求数目.

http {
log_format  main  
' $remote_user [$time_local]  $http_x_Forwarded_for $remote_addr  $request '
'$http_x_forwarded_for '                     
'$upstream_addr '                     
'ups_resp_time: $upstream_response_time '                     
'request_time: $request_time';
access_log  logs/access.log  main;
server{}
...
}

　　在日志显示的信息为:

- [31/May/2013:00:01:03 -0700]  - xxx.ip.addr.xxx  GET /portal/index.html HTTP/1.1 - 192.168.100.15:8188 ups_resp_time: 0.010 request_time: 0.011
