新增nginx配置文件nginx.status.conf
[root@vrgv /]# vim /etc/nginx/conf.d/nginx.status.conf
server {
    listen 81;
    access_log off;
    server_name localhost;
    root /var/www/html;
    location /nginx_status {     #转发关键字
       stub_status on;             #打开status状态服务
       access_log off;             #关闭log功能
       allow 127.0.0.1;            #只允许本地访问
       deny all;                       #拒绝除了上面127.0.0.1独立设置的ip以外，所有的ip
    }
}
重新启动nginx
[root@vrgv bin]# systemctl restart nginx
访问测试两次
[root@vrgv bin]# curl http://127.0.0.1:81/nginx_status
Active connections: 1
server accepts handled requests
 1 1 1
Reading: 0 Writing: 1 Waiting: 0
[root@vrgv bin]# curl http://127.0.0.1:81/nginx_status
Active connections: 1
server accepts handled requests
 2 2 2
Reading: 0 Writing: 1 Waiting: 0
以上信息中：
#active   当前活动的客户端连接数，包括waiting连接数
#accepts  已接受的客户端连接数
#handled  已处理的连接总数
#requests 客户端请求的总数
#reading  正在读取请求头的当前连接数
#writing  将响应写回客户端的当前连接数
#waiting  等待请求空闲客户端的当前连接数

根据自己实际情况，找到zabbix-agent安装目录下，创建一个脚本目录和脚本文件
[root@vrgv /]# cd /etc/zabbix/
[root@vrgv zabbix]# ls
zabbix_agentd.conf  zabbix_agentd.d  zabbix_java_gateway.conf.rpmsave
[root@vrgv zabbix]# mkdir scripts
[root@vrgv zabbix]# cd scripts/
[root@vrgv scripts]# vim nginx-status.sh
#!/bin/bash
result="/usr/bin/curl -s http://127.0.0.1:81/nginx_status"
case $1 in
    active)
        $result |awk '/Active/ {print $NF}'
    ;;
    accepts)
        $result |awk 'NR==3 {print $1}'
    ;;
    handled)
        $result |awk 'NR==3 {print $2}'
    ;;
    requests)
        $result |awk 'NR==3 {print $3}'
    ;;
    reading)
        $result |awk '/Reading/ {print $2}'
    ;;
    writing)
        $result |awk '/Writing/ {print $4}'
    ;;
    waiting)
         $result |awk '/Waiting/ {print $6}'
    ;;
          *)
    echo "USAGE:$0 {active|reading|writing|waiting|accepts|handled|requests}"
esac

[root@vrgv scripts]# cd ../
[root@vrgv zabbix]# ls
scripts  zabbix_agentd.conf  zabbix_agentd.d  zabbix_java_gateway.conf.rpmsave
[root@vrgv zabbix]# vim zabbix_agentd.conf
全局搜索UserParameter参数
修改成:
UserParameter=nginx.status[*],/etc/zabbix/scripts/nginx-status.sh $1  #nginx.status是参数，需要与后面的zabbix-web模板中对应的对应，后面是脚本路径，需要注意权限问题。
重新启动zabbix-agent服务
[root@vrgv zabbix]# systemctl restart zabbix-agent

[root@zabbix ~]# zabbix_get -s 192.168.1.228 -p 10050 -k 'nginx.status[active]'
