[How-to] MRTG設定安裝
[free][color=red][size=5]I.安裝 snmp&snmpd&mrtg&mrtg-contrib[/size][/color]
[b]root [/usr/ports] # portupgrade -NfCcpy snmp snmpd mrtg mrtg-contrib[/b]

---> Installing 'mrtg-2.15.2,1' from a port (net-mgmt/mrtg)
[color=red][size=5]II.建立/usr/local/share/snmp/snmpd.conf[/size][/color]
[b]root [/usr/ports] #ee /usr/local/share/snmp/snmpd.conf[/b]
---------------------------------------------
裡面加入
rocommunity public

[color=red][size=5]III.測試 snmp[/size][/color]
[b]root [/usr/ports] # snmpwalk -c public -v 1 localhost[/b]
會有如這樣的訊息出現

表示正常。
[color=red][size=5]IV.使用cfgmaker來產生我們所要監控的設備組態檔[/size][/color]
[b]root [/usr/ports] # cfgmaker --global 'WorkDir: /www/mrtg' \
--global 'Options[_]: bits,growright' \
--global 'Language: big5' \
--output /etc/mrtg.cfg \
[color=red]public@domain.name[/color][/b]
*1. /www/mrtg 是將來看統計輸出的地方, 要檢查目錄是否存在, apache 是否可以知道這地方.
*2. [email=public@domain.name]public@domain.name[/email] 這裡要特別注意唷!
必須把 domain.name 換成您主機的 domain.name。
[color=yellow]
若是想要了解你的主機User CPU Load % CPU (user and system) Load % Active CPU Load %這一些資訊的話，可以自己編輯 mrtg.cfg 檔案在最後面加上這些設定
