打开 Nginx 的 status 页面，并重启
[root@zabbix vhosts]# cat nginx_status.conf
server {
listen 90;
server_name _;
location /ngx_status {
stub_status on;
access_log off;
allow 127.0.0.1;
deny all;
}
}
[root@zabbix vhosts]# nginx -s reload
本地访问测试
[root@zabbix vhosts]# curl http://127.0.0.1:90/ngx_status
Active connections: 2 # 活跃的连接数量
server accepts handled requests
12178 12178 18413 # 总共处理了12178个连接 , 成功创建12178次握手, 总共处理了18413个请求
Reading: 0 Writing: 1 Waiting: 1 # 读取客户端的连接数: 0 响应数据到客户端的数量: 1 Nginx 已经处理完正在等候下一次请求指令的驻留连接(开启 keep-alive 的情况下,这个值等于 active – (reading+writing))
