Web页面提示拒绝连接：Get value from agent failed: cannot connect to [xx.xx.xx.xx]: [113] No route to host，可用性和ZBX小字显示红色
1.首先查看防火墙有没有放行10050端口，注意像阿里云腾讯云有另外的物理防火墙，一并开
2.被监控端agentd服务没有运行，输入命令查看服务有没有运行:
ps -ef | grep zabbix-agent没有即开启，若有报错再对症下药
3.检查selinux状态是否为disable
cat /etc/selinux/config SELINUX=disabled没有就设置为disable
