Ernie:
Trying to make sense of this output below. Would I have to do the math to
get my number. i.e. subtract Octets and devide by seconds, or is there a
way to just see the average per interval from the CLI? I see % utilization
which could be helpful but it is 0 for both your example and mine. Perhaps
that doesn't show anything unless we get to a certain level of throughput.
I see how to do it now in NS and OneView. It would be nice to be able to
do it from the CLI too but if I have to do the math I'll stick to NS.
Thanks
