Okay, at this point I'm just working on the math. :) Can someone let me
know if I'm going in the wrong direction.
I read in the MRTG log file.
Split it up into the 5 pieces. time, in, out, maxin, & maxout.
Run though and break up the information into the 4 curves.
Search for missing intervals.
Take missing intervals and look for data in that interval and
create a value. (Currently from more recent data, I should
probably also look at the history for current interval.)
I will also take the largest value found and stick it in as the
max for the interval.
That's it for now. Comments are very welcome.
