Matt -
The interfaces I monitor are all half-duplex. I am now charting the
inbound and outbound separately, and will soon (Pending the script
working), have a tally underneath which calculates in+out / max available.
I'm not sure I understand your calculations for full-duplex though. By
"max of the in and out" , do you mean that you take the HIGHER of the in
or out, whichever it may be, and base the percentage on that? Okay. That
makes sence (Had to write it out before it looked right....)

HI,
Hw do you handle whether the interface is Full Duplex or Half? In my
non-graph data, I do it this way:
Half-Duplex => Add the in+out for my total bits
Full-Duplex => Take the max of the in and out
Do you guys do it the same way ? Or do you differentiate?
Cheers
Matt
