Zabbix介紹
爲什麼要監控
我們的職責
1. 保障企業數據的安全可靠。
2. 爲客戶提供7*24小時服務
3. 不斷提升用戶體驗
在關鍵時刻，提前提醒我們服務器要出問題了
當出問題之後，可以便於找到問題的根源
怎麼來監控
遠程管理服務器有遠程管理卡，比如Dell idRAC，HP ILO，IBM IMM
查看硬件的溫度/風扇轉速，電腦有魯大師，服務器就有opmitool。使用ipmitool實現對服務器的命令行遠程管理
ü yum -y install OpenIPMI ipmitool àIPMI在物理機可以成功，虛擬機不行
CPU性能好不好、忙不忙可以用lscpu、uptime、top、htop。
內存夠不夠可以用free
磁盤剩多少寫的快不快可以用df、dd、iotop
網絡太卡找iftop，nethogs
