MRTG 安裝與應用

rpm -q mrtg

[docsrv@ed ~]$ rpm -q mrtg
mrtg-2.10.15-1

• 如果沒有安裝, 就執行 yum -y install mrtg 來安裝

rpm -q net-snmp

[root@pd920 ~]# rpm -q net-snmp
net-snmp-5.1.2-11.EL4.7

• 如果沒有安裝, 就執行 yum -y install net-snmp 來安裝

vi /etc/snmp/snmpd.conf

com2sec notConfigUser  default       public

service snmpd restart
chkconfig snmpd on 
chkconfig --list | grep snmpd

• 假設已經安裝 trysrvtool 在 /opt/trysrvtool/, 就可以在 /opt/trysrvtool/mrtg/ 底下看到相關的 scripts

• 先使用 runcfgmaker.sh 獲取目前網卡資訊

cd /etc/mrtg
/opt/trysrvtool/mrtg/runcfgmaker.sh
cat localhost.cfg >> mrtg.cfg
vi /etc/mrtg/mrtg.cfg
