使用現有模板和監控項監控主機流程

在被監控的主機上安裝Zabbix Agent ,建議和 Zabbix Server 同一個版本配置 Zabbix agent的配置文件關鍵兩項,并重啟服務生效 --> Server =  --> Hostname=<本機IP>在Zabbix Server 上使用 zabbix_get 工具測試是否正常連接被監控主機在Zabbix Server 添加被監控主機在Zabbix WEB 添加已有的模板至被監控的主機在Zabbix WEB 觀察是否有新數據生成下面是具體案例

Zabbix Agent 需要安裝到被監控的主機上，它負責定期收集各項數據，并發送到zabbix server端，zabbix server將數據存儲到數據庫中，zabbix web 訪問數據庫在前端進行展現和繪圖。
