[mrtg] Definition of peak inbound & outbound traffic?

[Scott Neader]

Spent considerable time searching, but came up empty. What is the
definition of "Peak inbound traffic" and "Peak outbound traffic" on my
weekly, monthly and yearly graphs? (and how does this differ from the
regular "Inbound traffic" and "Outbound traffic" graphs?

TIA,

I'm assuming you have the default 5-min sample interval.

The daily graph is a 5-min granularity, the weekly is a 30-min
granularity, the monthly is a 2-h granularity, and the yearly is a 1-day
granularity.

The daily graph will show you a line corresponding to the 5-min average
(because you are polling every 5 minutes).

The 'Peak' line on the Weekly graph will show the highest 5-min average
for the 30-min period. The normal line will show the Mean Average over
the 30-min period (IE, the average of the six 5-min averages)

The 'Peak' line on the Monthly graph will show the highest 5-min average
for the 2-h period. The normal line will show the Mean Average over the
2-h period.

And so on.

Not certain these two parts are correct, my examples will explain why

My weekly PEAK (Or MaxIn/MaxOut) hasn't changed from 7.82Mb/s (total) in 5
days. I can only assume that because the day those peaks occurred is still
within the 7 day range being graphed. If it happened on Sunday, then those
peaks would be there until either A) new peaks occur within 7 days or B) the
stat falls off on the next Sunday (as 7 days have now passed) and the new
Peak will be the next highest MaxIn/MaxOut totals. Which could be anything
that happened on the previous Monday to the current (next) Sunday.

Or am I referring to something different than was asked? Heh, or am I just
flat out wrong? :-)
