I'm trying to figure out what exactly this metric is. I have PRTG monitor net traffic from our company's router. I understand speed seems to be overall bandwidth, seeing as how this metric matches up to a bandwidth monitoring our ISP uses. As far as volume, I'm more in the dark. For example, my speed(bandwidth?) might be at 264,000kbits/s while my volume is just shy of 900,000kbits/s.
I figure this is something very simplistic, that I just can't seem to find any information on. Thanks!
