测试nginx状态信息的一个模块HttpLogRequestSpeed，找到网页瓶颈，官方提供了一个模块的源码和一个分析脚本，脚本是pl的。
、HttpLogRequestSpeed模块下载地址：
###HttpLogRequestSpeed Module###
http://wiki.nginx.org/File:Ngx_http_log_request_speed.tar.gz ###Log Analyzer.pl### http://wiki.nginx.org/File:Log_Analyzer.tar.gz
2、重新/全新编译
[root@ipython nginx]# ./sbin/nginx -V
nginx version: nginx/1.7.5 built by gcc 4.4.7 20120313 (Red Hat 4.4.7-4) (GCC) TLS SNI support enabled configure arguments: ...[省略] --add-module=../ngx_http_log_request_speed
3、Nginx配置：
###该过滤器支持使用在location, server, http####
http { ##enable / disable## log_request_speed_filter on; ##timeout## log_request_speed_filter_timeout 1; ##Log 级别需要注意一下，吐出来的log就在error里面## error_log /software/var_temp/log/nginx/nginx_error.log error; }
4、日志示例(输出域名做了修改)：
[root@ipython nginx]# tail -5 /software/var_temp/log/nginx/nginx_error.log
