Problem with Sum - CDEF function

[SergioAbe]

Good morning!

I made the follwing CDEF funcion:

Traffic_Out : b,d,f,h,+,+,+,8,*
Traffic In : a,c,e,g,+,+,+,8,*

And see the picture in annex to clarify.

In the MAX item I have b=935.83 M
d=10.60 K
f=210.86 M
h=10.73K

The total should be = 1.15 G, but the Cacti shows 983.96 M.

What is wrong in this case?

The Last (Atual) and Average (Media) the value is correct!!!

Thanks in advance.

Traffic_Out : b,d,+,f,+,h,+,8,*
Traffic In : a,c,+,e,+,g,+,8,*

I have the same results with initial formula.

[BenGonGon]

how have you construct your graph and addition ?

[camerabob]

Why the *8 at the end?

[SergioAbe]

BenGonGon

Yes. I construct de graphics. The result of sum is the same value.

*8 to convert bytes in bits.

Yes, I separate the lines of In and Out.

[SergioAbe]

The sum of Average and Last are correct value.

The problem is only in MAX!.
