How does Intermapper find the Byte/second and bits/second that it

I assume it's polling a MIB variable... maybe octets per second? and
then polling a second time and doing a calcualtion?  What MIB
variable???

I'm asking because I want to do some manual polling (for a project I'm
working on) and get the same data.

In general, InterMapper uses ifInOctets and ifOutOctets from MIB-II for SNMPv1, and the high capacity variants (ifHCInOctets and ifHCOutOctets, when available) for SNMPv2c/v3.
