mrtgのインストール・設定

mrtgを入れました。
まずはyumでインストール。

# yum install net-snmp
# yum install net-snmp-utils
# yum install mrtg

/etc/snmp/snmpd.confを編集。

# sec.name source community
#com2sec notConfigUser default public
com2sec local localhost private
# groupName securityModel securityName
#group notConfigGroup v1 notConfigUser
#group notConfigGroup v2c notConfigUser
group MYROGroup v1 local
group MYROGroup v2c local
group MYROGroup usm local
# Make at least snmpwalk -v 1 localhost -c public system fast again.
# name incl/excl subtree mask(optional)
#view systemview included .1.3.6.1.2.1.1
#view systemview included .1.3.6.1.2.1.25.1.1
view all included .1 80
# group context sec.model sec.level prefix read write notif
#access notConfigGroup "" any noauth exact systemview none none
access MYROGroup "" any noauth exact all all none
#disk / 10000
disk / 10000

そしてsnmpdを起動。

# /etc/rc.d/init.d/snmpd start
# chkconfig snmpd on

/etc/mrtg.mrtg.cfgの編集。

mrtgを実行。

# mrtg /etc/mrtg/mrtg.cfg
# mrtg /etc/mrtg/mrtg.cfg
# mrtg /etc/mrtg/mrtg.cfg

インデックス作成。

indexmaker /etc/mrtg/mrtg.cfg > /var/www/mrtg/index.html

以上ですべて完了。
今のところはうまく動いているようです。
