Hello,
Yesterday a did this to try to get this working:
bla:/data/nfsen/libexec# vi NfSenRRD.pm
# my $sampling_rate = exists
NfConf::sources{$channel}{'sampling_rate'} ?
NfConf::sources{$channel}{'sampling_rate'} : 1;
$profileinfo{'channel'}{$channel}{'scale'} =
$profileinfo{'channel'}{$channel}{'sign'} eq "-" ? -1 : 1;
push @DEFS,
"DEF:data${channel}=$NfConf::PROFILESTATDIR/$profiledir/${channel}.rrd:${what}:AVERAGE";
# my $sampling_rate = exists
NfConf::sources{$def}{'sampling_rate'} ?
NfConf::sources{$def}{'sampling_rate'} : 1;
$$profileinfo{'channel'}{$def}{'scale'} =
$$profileinfo{'channel'}{$def}{'sign'} eq "-" ? -1 : 1;
#-----------------------------------------------------------#
I changed -1 : 1 to -1000 : 1000 this is the sample rate i am using.
It seems to work but it would be much nicer not to hack the code and to
configure it with every channel... This doesn't change the "raw" data
output when you want to process something. It only changes the graphs.
Thanks,
Koen
