• 给脚本赋予执行权限

[root@localhost scripts]# chmod +x nginx_status.sh

• 在/etc/zabbix/zabbix.agent.d/目录下创建一个配置文件

[root@localhost scripts]# vim /etc/zabbix/zabbix_agentd.d/nginx_status.conf
UserParameter=nginx_status[*],/bin/bash /scripts/nginx_status.sh "$1"

• 重启agent端zabbix-agent服务

[root@localhost scripts]# systemctl restart zabbix-agent

• 在server端进行测试

[root@localhost init.d]# zabbix_get -s 192.168.91.134 -k "nginx_status[server]"
