Nginx 开启status用以监控状态信息

Nginx 可以通过with-http_stub_status_module模块来监控nginx的一些状态信息。

通过nginx -V来查看是否有with-http_stub_status_module该模块。

# nginx -V

修改nginx.conf

# 加入如下代码

  location =/nginx_status/ {
        # Turn on nginx stats
        stub_status on;
        # I do not need logs for stats
        access_log   off;
        # Security: Only allow access from IP #
        allow zabbix_server;
        # Send rest of the world to /dev/null #
        deny all;
    }

# end 
  ....
  
  location / {
    ....
  }

重新启动nginx，并访问http://localhost/ngx_status。

Active connections: 1 
server accepts handled requests
 3 3 57 
Reading: 0 Writing: 1 Waiting: 0

Active connections: 表示Nginx正在处理的活动连接数。

server: 表示Nginx启动到现在共处理了多少个连接

accepts: 表示Nginx启动到现在共成功创建几次握手

handled requests: 表示总共处理请求数

Reading: Nginx 读取到客户端的 Header 信息数

Writing: Nginx 返回给客户端 Header 信息数

Waiting: Nginx 已经处理完正在等候下一次请求指令的驻留链接（开启keep-alive的情况下，这个值等于Active-(Reading+Writing)
