[mrtg] Chart never moves.

[Gary W. Smith]

Jan, 

That does makes sense.  I know I encountered this problem long ago but I
just couldn't remember how to fix it.  In this case, where the interface
will only go up (soon to be TB range), what should I use for Maxbytes?
Is there a way to say nomaxbytes?  

The current workaround (since the IF is limited to 10mb for this set),
is to just subtract 7fff ffff from the value in a loop until it drops to
a sane number and it seems to work.  I had to take absolute out of the
options and the subtraction method works (thought this is a very bad
kludge workaround).

I will spin up a second copy of this and try it with an arbitrarily
large Maxvalue and run them side by side for a while to compare.

Gary,

Nothing wrong with long longs.
The Maxbytes value in your config file is too low.

Everything above the maxbyts value is dropped by MRTG.

HTH,

Jan.

Yes, I have it cron'd for every 5 minutes.  The problem seems to be
dealing with long long's.  I worked up in the perl script to subtract
4294967296 until it's lower than 4294967296.  That kind of works but I
had odd results.  I tried the same with 2147483647 (I case it was dying
on signed longs) and it also gave me some odd data).

This is with mrtg-2.15.0.  Should this be able to handle long longs?

Gary
