So do I ;)
Calling RRDs::xport returns with an array containing:
my ($start,$end,$step,$columcnt,$legend,$data)=RRDs::xport(@cmd);
With this information you can loop over the the data like this:
foreach my $row (@$data)
{
(undef,my $min,my $hour,my $mday,my $mon,my
$year,undef,undef,undef)=localtime($start);
$line.=sprintf("%u\t%02u-%s-%04u
%02u:%02u",$start,$mday,$Months[$mon],$year+1900,$hour,$min);
$start+=$step;
foreach my $val (@$row)
{
if ($val ne '')
{
$line.=sprintf("\t%.2f",$val);
} else
{
$line.=sprintf("\tNaN\n",$val);
}
}
}
See ... No need to call a XML parser ;)
You can take a look in the file shared-demo.pl bundled with rrdtool in the
examples
directory.
HTH,
Andreas.
