mrtg中CPU的oids怎么写啊

cuiy

我是单cpu的机器，.1.3.6.1.4.1.2021.10.1.5.1&.1.3.6.1.4.1.2021.10.1.5.2是一台双cpu的机器上的值。
这种值跟什么参数有关系，都是固定的吗？

  </TABLE>;

我把oids替换为.1.3.6.1.4.1.2021.10.1.5.1
用mrtg执行cfg文件时，总是提示：
$target->;[0]{$mode} ' evaluated to '撺
49489' instead of a number

把1.3.6.1.4.1.2021.10.1.5.2去掉后

重头又作了多遍
感觉cpu的oids的值写得没有错。好像snmp之间的协议有些问题。
两台机器，相互的网络流量都没有问题。但是监测cpu 都报相同的错误

那位对snmp比较了解一些，还往能够指导一下：）

cisco的我做通了可以检测CPU如果通过MEMORY的OID也一样可以，你可能是OID搞错了，或者是格式写的不对，
好象要写成x.x.x.x.x.x.x.x.x.x&x.x.x.x.x.x.x.x.x.x:public@Ipaddress
你可以用软件DOWN   MIB在生成HTML文件查查OID对不对。
