The short answer is, likely, that you will need to make changes
to the source-code for check_local_mrtgtraf and that's beyond the
remit of the Icinga folks.
The long answer is even worse. Measuring bits per second is
a different animal than measuring bytes (or, more properly in
comms terms, "octets") per second -- and it depends on what values
your piece of comms gear is reporting in. Line speeds are commonly
reported by humans as bit-rates; however, most of the comms gear
I've seen reports in octets when being queried by SNMP (the most
common mechanism, and one that MRTG uses extensively). Fortunately
the difference is a matter of simple multiplication, but at that
point you're into making changes to the source-code either on the
data-gathering end of things or on the reporting side of things
(do *not* do both).
Cheers!
