[rrd-users] overhead of value

[Mauricio Doria de Camargo]

I have a problema to display date over 120Mb on Gigaethernet ports.

Attached follow the graphic to ilustrate my problem.

When the traffic get over about 120Mbists the points are plotted bellow on
the graphic.


The values stored are octects (bytes), so I multiply (x8) it to get bits per
second:

        RRDs::graph "-",
                "-w $px", "-h $py", "-i",
                "-s -$periodo",
                "-e $hora",
                "-v Bits per Second",
                "DEF:mii=$HPDIR/dados/$switch.rrd:i$porta:MAX",
                "DEF:moo=$HPDIR/dados/$switch.rrd:o$porta:MAX",
                "CDEF:mi=mii,8,*",
                "CDEF:mo=moo,8,*",
                "AREA:mi$cores[0]",
                "LINE1:mi$cores[1]",
                "LINE2:mo$cores[2]"

Is there any limitation for values to plot?
What can I do to solve that?
