Then it strikes me as odd too that you want to graph it instead of
gprinting it.
If however you just want a line representing total traffic, you can do
it like this:

- calculate the total traffic by doing avg bps * timespan
- call rrdtool graph with a print statement to print the average value
of that total traffic
- catch the output and use it to call rrdtool again. This time let it
draw a line or hrule with the value.

Lo all,

First, I spend numerous hours browsing the archives, and on google -
with no
luck.  Frankly, I don't think google returns a hit that I have not
visited
related to this...

I want to *graph* the *total* MB/GB used on a Interface over a certain
period of time (not fixed)...

Now, the whole kb/sec * times = Value thing is all nice and fine...
HOWEVER,
when *graphing* that, it doesn't exactly make allot of sense when your
TOTAL
traffic goes up and down and up and down, does it?  I mean, traffic used
is
traffic used and it cannot go down (except if the counters are reset)...
And
let's face it.. A interface runs at 500kb/sec for 1 hour, and then goes
into
a idle state for 4 hours... Graphing that with kb/sec * time, the graph
will
go high, and then go down to zero (just about)...

I want a way to graph the traffic used per time period, that should look
very similar to the old mrtg "uptime" graphs for example - similar type
of
graph. Myself, just as allot of others (from what I saw in the archives)
are
unable to do it, and are unable to get a answer from this mailing list
on
how to do it... I know it is possible however, seeing that I saw allot
of
other people *graphing* the totals... So, just how is this done???

If this has been answered before, please just point me to the post in
the
archives... After spending numerous hours searching and browsing, I'm
rather
sure that I could not have missed it.
