为了让系统在启动的时候自动启动snmpd监听服务，我们要对/etc/rc.conf进行配置，在该文档种添加下面内容：
snmpd_enable=”YES”
snmpd_flags=”-a -p /var/run/snmpd.pid”
snmptrapd_enable=”YES”
snmptrapd_flags=”-a -p /var/run/snmptrapd.pid”
下面参数可选
NET_SNMP_SYS_CONTACT=”Michael@toplee.com”
NET_SNMP_SYS_LOCATION=”Beijing,China”
DEFAULT_SNMP_VERSION=3
NET_SNMP_MIB_MODULES=”host smux mibII/mta_sendmail ucd-snmp/diskio”
NET_SNMP_LOGFILE=/var/log/snmpd.log
NET_SNMP_PERSISTENTDIR=/var/net-snmp
3、安装mrtg-2.13.2
在完成了上面的snmp安装配置之后，开始进行mrtg的安装配置，也使用很方便的ports进行安装
#cd /usr/ports/net-mgmt/mrtg/
#make install clean
4、配置mrtg
#vim /usr/local/etc/mrtg/mrtg.cfg
下面是我的配置文档
