mrtg监控squid状态不成功

lymrg

(1)我们需要修改squid
vi /etc/squid/squid.conf
acl snmppublic snmp_community public (设置snmp监控的共同体为public)
snmp_port 3401(设置snmp监控端口)
snmp_access allow snmppublic all(允许所有的计算机访问snmppublic)
然后从新启动squid /etc/rc.d/init.d/squid restart
(2)把/etc/squid/mib.txt 复制到/etc/mrtg/squid.mib
cp /etc/squid/mib.txt /etc/mrtg/squid.mib
(3)然后修改/etc/mrtg/mrtg.cfg
加入LoadMIBs: /etc/mrtg/squid.mib
(4)在/etc/mrtg/mrtg.cfg加入如下

保存文件,并运行mrtg mrtg.cfg
然后出现了下面的报错信息

请大虾帮忙解决一下
