The MIB defines these counters as totals but the NV data collector
calculates delta rates i.e it takes differences between successive poll
samples and divides by the polling interval. So you get bytes/sec values,
which can be (usually are) in decimals.

Raw ifInOctets and ifOutOctets are totals - try an snmpget on each one. But
the data collector stores rates of change. (This makes plotting easier.)

To do that, you build an expression from MIB variables.
