使用snmp+mrtg監(jiān)控CPU、流量、磁盤空間、內(nèi)存

1、使用 snmp+mrtg監(jiān)控 cpu 、流量、磁盤空間、內(nèi)存1、 安裝 snmpyum install net-snmp* -y2、 修改/etc/snmpd.conf(可直接清空內(nèi)容 ) 增加 rocommunity public 找到 disk 修改(df k 查看) 可以有多個(gè) , 看情況disk / $size disk /boot $size1disk /home $size23、 啟動(dòng)/etc/init.d/snmpd restart4、 安裝 mrtgyum install mrtg* -y5 將以下內(nèi)容寫到 /etc/mrtg/mrtg.cfg,直接覆蓋 ( 黃色背景需更改 )
