nginx监控指标
- ngx_http_stub_status_module:http://nginx.org/en/docs/http/ngx_http_stub_status_module.html
- 用nginx-rrd监控nginx访问数:http://laoxu.blog.51cto.com/4120547/1159491
ngx_http_stub_status_module模块能够获取Nginx自上次启动以来的工作状态。
此模块非核心模块，需要在编译的时候手动添加编译参数--with-http_stub_status_module。

"stub status" 模块返回的状态信息下：
Active connections: 291 server accepts handled requests 16630948 16630948 31070465 Reading: 6 Writing: 179 Waiting: 106
-
Active connections- 当前连接数(包括Waiting状态的连接)。
- The current number of active client connections including Waiting connections.
-
server accepts handled requests-
accepts:nginx 总共处理了 16630948 个连接(The total number of accepted client connections)。 -
handled:成功创建 16630948 次握手(证明中间没有失败的)。The total number of handled connections. Generally, the parameter value is the same as accepts unless some resource limits have been reached (for example, the worker_connections limit). -
requests:总共处理了 31070465 个请求 (平均每次握手处理了1.8个数据请求)。The total number of client requests.

reading-- The current number of connections where nginx is reading the request header. -
