Hi All,
I have about a thousand RRD files, one for each IP addresss inside our
network. I'd like to be able to sort these IPs by "total" traffic over
a period of time (to see which IPs are using the most traffic).
Currently I have a cgi script that calls RRDs::fetch and sums all the
data points by hand, but with 1000 RRD files, this is way too slow. How
can I do it faster? I tried playing with the --resolution switch, but I
could not ever get it to return data in anything but the finest
resolution.
Here is roughly what I do, for each RRD file, to find the totals:
my ($start,$step,$names,$data) =
RRDs::fetch("$rrdfile",
"AVERAGE",
"-s $start",
"-e $end");
foreach my $line (@$data) {
$in += (@$line)[0] || 0;
$out += (@$line)[1] || 0;
$junk += (@$line)[2] || 0;
}
I imagine this is a common thing that people do: compute totals over a
range for an RRD file. Anyone have some tips on how I can speed things
up?
Thanks!
-Aaron
