[Apan-users] bandwidth utilization

[none n. <sfi...@gm...>]

Hi all ,

Regarding the bandwidth utilization plugin in the howto page , from what I
understand it's supposed to show the number of bytes
per-sec , but what it seems to be doing is building a set of the last values
of received/sent packets on a specified interface and then averging the
numbers in that set instead of calculating the difference between the
current and last received/sent packets value on the given interface and then
averaging the set of the differences , which is what it supposed to do to
give an accurate bandwidth utilization .
for instance if the last 5 values of received packets were
100,200,300,400,500 in that order ( which is normal because the value will
never decrease unless it wraps around) , the average of those would be
((100+200+300+400+500)/5) when it's supposed to be
(((200-100)+(300-200)-(400-300)+(500-400))/4) , this later caculation is
necessary because these OIDs do not return the  "Bandwidth utilization" but
the number of packets received/sent on a given interface until the current
point in time .


Please correct me if I'm wrong .

Thank you
