Hello Luca, > How did you configure sflow in your foundry? I've configured the rate to 1 on all ports. After doing this, I can see that captured informations are better accurate but not 100%. For example, if I transfers 100 MB now, I will see around 90 MB. I think I cannot do better than that because it use sampling as you said.
