Re: Graphing Arista Switch Ports

Hi Paul,

I did mean too low on the ds[traffic_in/out].max values. I found in the
Data Template "Interface - Traffic" the Maximum Value is set to 100000000.
Since I'm trying to graph 1, 10, and 20 gigabit/sec interfaces that would
make sense why the data wasn't showing up.

Being completely new to Cacti, I think the appropriate area to modify this
value would be in the Data Template "Interface - Traffic" and I would bump
this up to 10000000000.

I realize
rrdtool tune fs1a_traffic_in_94.rrd --maximum
traffic_out.max:1000000000<callto:1000000000>
is the same as 1.0000000000e+09, however when I applied the above line the
graphs started to work. I'm not quite clear why this was the result.

Thanks for your input,
-Reza
