You could try running a fetch for the week and add up all the bytes that are
>1Mbps. If you're using Perl it would be something like this:
Assuming: You have the RRD shared module loaded in Perl
Your file is called 'bandwidth.rrd' for example purposes
---Start Code---
# Fetch a week's worth (604800 seconds) of data from bandwidth.rrd
my
($start,$step,$names,$data)=RRDs::fetch("bandwidth.rrd","AVERAGE","--start=-
604800");
# Reset the over limit count to zero
$totalover1Mbps=0;
# Examine each line returned from the fetch
foreach my $line (@$data) {
# Examine each value on each line returned by the fetch
foreach my $val (@$line) {
if($val > 1000000) { # The value is greater that 1Mbps
# Add the amount over 1Mbps to a total over counter
$totalover1Mbps=$totalover1Mbps+($val-1000000);
}
}
}
---End Code---
Then you should have a scalar called $totalover1Mpbs that you should be able
to include in a comment on the graph somewhere. I have to warn you, I'm
pretty new at Perl so this might not be the most efficient way of doing
things
Just a thought.

Subject: [rrd-users] Calculate area from graph?
Hello,
Im having some trouble with the graph...
I've attached a graph that shows all peaks over 1mbps with a gray area, is
it possible to calculate this area? The result should be total bytes
transferred during these peaks.
