parse xml for conky

graysky · 2010-12-06 22:51:32

I'd like to capture two key outputs and have them displayed in conky. On my system, GPU load and GPU memory usage are available from the nvidia-smi program. I can output in xml format which I'd like to parse and harvest to display in conky. I can brute-force myself through it via grep and sed statements, but I'm looking for some suggestions from more knowledgeable people to do this in a minimal way. For example, only run the program once, and harvest all data. My current solution runs twice.

Example output:

$ nvidia-smi -a -x
<?xml version="1.0" ?>
<!DOCTYPE nvsmi_log SYSTEM "./nvsmi.dtd">
<nvsmi_log>
    <timestamp>Mon Dec  6 17:48:50 2010</timestamp>
    <driver_version>260.19.21</driver_version>
    <gpu id="0">
        <prod_name>GeForce 8400 GS</prod_name>
        <pci_device_id>6e410de</pci_device_id>
        <pci_location_id>0:1:0</pci_location_id>
        <serial>2648101198649</serial>
        <display>Connected</display>
        <temp>43 C</temp>
        <utilization>
            <gpu_util>0%</gpu_util>
            <memory_util>8%</memory_util>
        </utilization>
    </gpu>
</nvsmi_log>
[facade@simplicity ~]$ nvidia-smi -a -x
<?xml version="1.0" ?>
<!DOCTYPE nvsmi_log SYSTEM "./nvsmi.dtd">
<nvsmi_log>
    <timestamp>Mon Dec  6 17:49:30 2010</timestamp>
    <driver_version>260.19.21</driver_version>
    <gpu id="0">
        <prod_name>GeForce 8400 GS</prod_name>
        <pci_device_id>6e410de</pci_device_id>
        <pci_location_id>0:1:0</pci_location_id>
        <serial>2648101198649</serial>
        <display>Connected</display>
        <temp>43 C</temp>
        <utilization>
            <gpu_util>5%</gpu_util>
            <memory_util>10%</memory_util>
        </utilization>
    </gpu>
</nvsmi_log>

Or it might be better not to go to xml which I can do by omitting the -x switch:

$ nvidia-smi -a

Proper XML processing is not streamed and would use more resources than grep | sed. But judging by the above, it doesn't look to be much.

nvidia-smi -a | awk -F '\t+: ' -v 'ORS= ' '$1 ~ /GPU$|Memory/ { print $2; }'

Deja vu all over again

Damn, my memory is truly shit. Thanks, ST. The awk syntax is still foreign to me. How would I segregate the RAM usage from the GPU usage? I think conky needs the output to be unique for each one in their own script.

EDIT: Got it.
