add power_limit to nvidia_smi

[jpvlerbe]

Use Case

To get the usage of the gpu I would like to use the percentage of power used. So from the output of nvidia-smi power_draw/power_limit

This seems to be a better metric to show usage than either the ram usage or gpu usage.

Expected behavior

next to power_draw include power_limit field

Actual behavior

only power_draw is included

Additional info

Or can somehow add this to the configuration?

Hi,

Please provide the output of /usr/bin/nvidia-smi -q -x so we can see an example.

In v12 I see numerous power limit fields.

Thanks

I am referring to this metric

which I am assuming corresponds to current_power_limit

I tried with fieldinclude=["current_power_limit"] but I am guessing that does not work as it is not in the list from the README or in parser.go (probably adding a line after line 80?)

@jpvlerbe I need you to run the nvidia-smi command above and get the output. Telegraf does not parse that table output, but instead the output from that command. I need to see what is available from the data that telegraf can see.

FWIW that 350W is the total cap value. Not something I would expect to see change.

I guess this is the v11 scheme, and the limit I am after is "power_limit"

I have 2 gpu's btw

You are making this harder than it needs to be with all these edits ;) just copy and paste without grep would have answered everything I need.

In ~30mins from this post, there will be artifacts in #15144 attached as a comment. Please download one of them and ensure the new power_limit field shows up.
