You say that you can come up with the numbers. Okay,
 then it's simple:

Either:
-a- The numbers are continuesly incrementing --> counter
-b- The numbers are reset when read --> absolute
-c- The numbers represent an average number of bytes per second --> gauge

Start with "N".  Then for each number, append ":" and the number to the
string.  Append the string you got to "rrdtool update some.rrd" and you're
done.

Read the tutorial for basic information on how to use counters, gauges,
absolutes etcetera.  Database creation is also covered in there, as is
graphing.
