Post subject:  Nvidia gpu RRD temperature graph in R6

Have been fiddling around attempting to add my nVidia gpu temperature to the RRD charts provided in R6, and against all odds......it seems to work :D

Image

If anyone else is interested, I made a few little mods to rrd_hdtemp.pl and just saved it as rrd_gputemp.pl

I imagine it should work with any nvidia gpu that displays a temperature in nvidia-settings??

Code:
#!/usr/bin/perl

#
# rrd_hddtemp.pl

use RRDs;

# define location of rrdtool databases

my $rrd = '/var/lib/rrd';
# define location of images
my $img = '/data/srv/httpd/htdocs/rrd';

# process data for each specified HDD (add/delete as required)
&ProcessHDD("gpu", "nVidia 8300 IGP");
#&ProcessHDD("sdb", "slave");
#&ProcessHDD("hdc", "40GB Seagate");
#&ProcessHDD("hdd", "secondary slave");

{
# process HDD

        # get hdd temp for master drive on secondary IDE channel
        my $temp=`nvidia-settings -c :0 -q gpucoretemp -t`;
        # remove eol chars and white space
        $temp =~ s/[\n ]//g;

        print "$_[1] ($_[0]) temp: $temp degrees C\n";

        # if rrdtool database doesn't exist, create it
        if (! -e "$rrd/$_[0].rrd")

If you follow rsay's instructions (mostly 6. and 7.) here: http://mysettopbox.tv/phpBB2/viewtopic.php?t=20619&sid=beb5802af56fc3713a51f90eb57d6961, it isn't too hard to add.

HTD.
