Hi,
I recommend taking a look at the data/trends message.
In short, you make a message with 1 rrd per GPU: [GPU-<number>.rrd] DS:counter1:GAUGE:600:0:U $value1 DS:counter2:GAUGE:600:0:U $value2
You send this is a data message: xymon $XYMSRV "data hostname.trends\n<message>"
This will create the .rrd dilws.
And then define a graph like:
[counter] FNPATTERN ^GPU-(.*).rrd
DEF:counter1@RRDIDX@=@RRDFN@:counter1:AVERAGE
TITLE Counter 1
YAXIS Counter
LINE1:counter1@RRDIDX@#@COLOR@:@RRDPARAM@:
GPRINT:counter1@RRDIDX@:LAST: cur\:%8.4lf
GPRINT:counter1@RRDIDX@:MAX: max\:%8.4lf
GPRINT:counter1@RRDIDX@:MIN: min\:%8.4lf
GPRINT:counter1@RRDIDX@:AVERAGE: avg\:%8.4lf \nStef

Hi,
I've stumbled upon a problem I cannot seem to solve myself and hope someone here can help me out...
A custom check I wrote is collecting data from Nvidia GPUs via the nvidia-smi command, the check works great and displays all the relevant data in its message, but I want to create graphs from certain data points too.
Here's my problem: in a server with 8 GPUs, I am collecting 5 different things from each GPU (like Power Draw, Utilisation and so on), these values get saved in a RRD file as well, but only the values from the first GPU.
I want to save a RRD file for each GPU and its values, so multiple data points in a RRD, but 8 different files (one per GPU) and I do not get how I can do this in a xymon check (bash script).
Can someone point me in the right direction here? What am I missing?
Thanks in advance!
Best regards Christoph
