nginx更多信息监控

    ngx_req_status用来展现nginx请求状态信息，相似于apache的status，nginx自带的模块只能显示链接数等等信息，咱们并不能知道到底有哪些请求、以及各url域名所消耗的带宽是多少。ngx_req_status提供了这些功能.

其功能特性：

（1）按域名、url、ip等等统计信息

（2）统计总流量

（3）统计当前带宽\峰值带宽

（4）统计总请求数量

安装：整个过程官网上也描述的比较清楚了。

wget "http://nginx.org/download/nginx-1.3.5.tar.gz"
tar -xzvf nginx-1.3.5.tar.gz
cd nginx-1.3.5/

patch -p1 < /path/to/ngx_req_status/write_filter-VERSION.patch

./configure --prefix=/usr/local/nginx \
            --add-module=/path/to/ngx_req_status

make -j2
make install

可是实际安装过程当中 始终没法编译经过，试了好几个版本，同时也在不一样机器环境上作了测试可是都报了相同的错误。

../ngx_req_status//ngx_http_req_status_module.c: In function ?.gx_http_req_status_handler?.

../ngx_req_status//ngx_http_req_status_module.c:306:41: error: variable ?.p?.set but not used [-Werror=unused-but-set-variable]

cc1: all warnings being treated as errors

make[1]: *** [objs/addon/ngx_req_status/ngx_http_req_status_module.o] Error 1

make[1]: Leaving directory `/usr/local/src/nginx-1.4.2'

make: *** [build] Error 2

最终经过万能百度的帮助解决了：

修改 objs/Makefile  去除文件中的 -Werror

从新编译 OK

配置nginx.conf

启用ngx_req_status

http {

 req_status_zone server_name $server_name 256k;

 req_status_zone server_addr $server_addr 256k;

 req_status_zone server_url  $server_name$uri 256k;

req_status server_name server_addr server_url;

server {

 server_name localhost;

 location /req-status {

 req_status_show on;

 }

 }

 }

测试：
