This is my nginx LogFormat configuration:

   1  log_format main '$remote_addr - $remote_user [$time_local] $status '
   2                      '"$request" $body_bytes_sent "$http_referer" '
   3                      '"$http_user_agent" "http_x_forwarded_for"';

And this is my Awstats LogFormat configuration:

   1  LogFormat = "%host - %host_r %time1 %code %methodurl %bytesd %refererquot %uaquot %otherquot"
