2 or more Nginx machines
each machine has the same virtual hosts
traffic is load balanced via DNS to each machine

我需要弄清楚什么是最好的工具来获取一些流量统计数据,主要是对点击量和总流量(千兆字节)感兴趣.显然,日志信息将来自Nginx,格式如下：

log_format  main  '$remote_addr $host $remote_user [$time_local] "$request" '
                    '$status $body_bytes_sent "$http_referer" "$http_user_agent" "$gzip_ratio"';
