Nginx日志分析脚本 | Nginx Log Analyzer

Nginx日志分析脚本 | Nginx Log Analyzer

日志格式使用标准的即可
log_format main '$remote_addr - [$time_local] "$host" "$request" '
'$status ($bytes_sent) "$http_referer" '
'"$uri $args" [$request_time]';
access_log /var/log/nginx/access.log main;

使用方法
./nginx-log-analyzer /var/log/nginx/access.log 1000

脚本代码

PHP写的

#!/usr/bin/php5
