mrtg 在红旗 4。0上无法显示流量的问题，请各位网友支持

Question

我参考了很多朋友的帖子，预先安装了APACHE（但我不知道MRTG对APACHE有什么特殊要求，按标准安装的，没有改任何地方）。
  METG是安装的2.10.13，安装都正常。默认安装的是NET.SNMP
  SNMPD.CONF和MRTG.CFG都参考别人的帖子改了，配置中没发现有不对的错误提示，但在HTTP浏览器里却只能显示MRTG的界面，但没有绿色的流量显示。不知道为什么不能看流量。
配置文件如下：
First, map the community name "public" into a "security name"

#       sec.name  source          community
com2sec notConfigUser  default       public

####
# Second, map the security name into a group name:

#       groupName      securityModel securityName
group   notConfigGroup v1           notConfigUser
group   notConfigGroup v2c          notConfigUser

####
# Third, create a view for us to let the group have rights to:

#       name           incl/excl     subtree         mask(optional)
view    mib2    included .iso.org.dod.internet.mgmt.mib-2 fc       
# Finally, grant the group read-only access to the systemview view.

#       group          context sec.model sec.level prefix read   write  notif
access  notConfigGroup   ""    any     noauth  exact  mib2    none       none在SYSLOCATION 前又加了一句rocommunity public

下面是MRTG.CFG配置文件,基本全是自动生成的,只改了

# Created by
# /usr/local/mrtg/bin/cfgmaker --output=/etc/mrtg.cfg public@10.8.145.34
