I am trying to use IOG into my network which consists of 5 subnets & totally 32 computers . However i am confused what index of ifInOctets to give as for routers atleast 33 entries each for ifInOctets(like ifInOctets.1 , ifInOctets .2.....) and similarly for ifOutOctets. If I try to give one entry which has non-zero value then its giving my results like 3-9GB/sec

In dire of solution ...... Please help me
