实验环境

服务端	客户端
主机名	C1	C2

#启动nginx
[root@C2 ~]# nginx
[root@C2 ~]# ss -antl

[root@C2 ~]# systemctl restart firewalld.service 
[root@C2 ~]# setenforce 0
#配置nginx
[root@C2 ~]# vim /usr/local/nginx/conf/nginx.conf
        location /nginx_status {
            stub_status on;
            allow 127.0.0.1;
            allow 192.168.96.133;
            deny all;
        }
[root@C2 ~]# nginx -s reload

编写脚本

[root@C2 ~]# mkdir /scripts
[root@C2 ~]# vim /scripts/check_nginx.sh
#!/bin/bash
#Script to fetch nginx statuses for monitoring systems
 
HOST="127.0.0.1"
PORT="80"
function active {
    /usr/bin/curl "http://$HOST:$PORT/nginx_status/" 2>/dev/null| grep 'Active' | awk '{print $NF}'
}
function reading {
    /usr/bin/curl "http://$HOST:$PORT/nginx_status/" 2>/dev/null| grep 'Reading' | awk '{print $2}'
}
function writing {
    /usr/bin/curl "http://$HOST:$PORT/nginx_status/" 2>/dev/null| grep 'Writing' | awk '{print $4}'
}
function waiting {
    /usr/bin/curl "http://$HOST:$PORT/nginx_status/" 2>/dev/null| grep 'Waiting' | awk '{print $6}'
}
function accepts {
    /usr/bin/curl "http://$HOST:$PORT/nginx_status/" 2>/dev/null| awk NR==3 | awk '{print $1}'
}
function handled {
    /usr/bin/curl "http://$HOST:$PORT/nginx_status/" 2>/dev/null| awk NR==3 | awk '{print $2}'
}
function requests {
    /usr/bin/curl "http://$HOST:$PORT/nginx_status/" 2>/dev/null| awk NR==3 | awk '{print $3}'
}
$1
[root@C2 ~]# chmod +x /scripts/check_nginx.sh

zabbix-agent配置文件开启自定义功能

[root@C2 ~]# vim /usr/local/etc/zabbix_agentd.conf
UnsafeUserParameters=1   #取消注释并改为1
在最后的空白处添加
UserParameter=check_nginx[*],/bin/bash /scripts/check_nginx.sh $1
[root@C2 ~]# zabbix_agentd 

测试server端是否可以收到数据

[root@c1 ~]# zabbix_get -s 192.168.96.133 -p 10050 -k check_nginx[accepts]

[root@c1 ~]# zabbix_get -s 192.168.96.133 -k check_nginx[active]
