1、服务端安装zabbix-get安装
Zabbix-Get 是Zabbix 中的一个程序，用于Zabbix-Server 到Zabbix-Agent 的数据获取，通常可以用来检测验证Agent 的配置是否正确。

2、验证Agent端CPU信息（120.55.*.*改成你要监控的主机IP）
root@zabbix-server:~# zabbix_get -s 120.55.*.* -k system.cpu.util[,user]
22.025549
root@zabbix-server:~# zabbix_get -s 120.55.*.* -k system.cpu.util[,system]
0.642738
root@zabbix-server:~# zabbix_get -s 120.55.*.* -k system.cpu.util[,idle]
77.281456
root@zabbix-server:~# zabbix_get -s 120.55.*.* -k system.cpu.util[,iowait]
3、创建对应的监控项
（1）一次点击ConfigurationèHostsèGroup(选择监控主机所在的组)èItems
（2）创建Create Item
（3）配置监控项，监控CPU空闲率
（4）点击Add保存添加
（5）完成自定义监控项目
（6）查看最新数据
（7）同样的方式添加你需要监控的项，你可以根据自己实际需求监控CPU信息
