nvidia-smi Input Plugin

This plugin uses a query on the nvidia-smi binary to pull GPU stats including memory and GPU usage, temp and other.

Configuration
# Pulls statistics from nvidia GPUs attached to the host
[[inputs.nvidia_smi]]
  ## Optional: path to nvidia-smi binary, defaults to $PATH via exec.LookPath
  # bin_path = "/usr/bin/nvidia-smi"

  ## Optional: timeout for GPU polling
  # timeout = "5s"
Windows

On Windows, nvidia-smi is generally located at C:\Program Files\NVIDIA Corporation\NVSMI\nvidia-smi.exe On Windows 10, you may also find this located here C:\Windows\System32\nvidia-smi.exe

You'll need to escape the \ within the telegraf.conf like this: C:\\Program Files\\NVIDIA Corporation\\NVSMI\\nvidia-smi.exe

Metrics

Sample Query

The below query could be used to alert on the average temperature of the your GPUs over the last minute

SELECT mean("temperature_gpu") FROM "nvidia_smi" WHERE time > now() - 5m GROUP BY time(1m), "index", "name", "host"
Troubleshooting

Check the full output by running nvidia-smi binary manually.

Linux:

sudo -u telegraf -- /usr/bin/nvidia-smi -q -x

Windows:

"C:\Program Files\NVIDIA Corporation\NVSMI\nvidia-smi.exe" -q -x

Please include the output of this command if opening an GitHub issue.

Limitations

Note that there seems to be an issue with getting current memory clock values when the memory is overclocked. This may or may not apply to everyone but it's confirmed to be an issue on an EVGA 2080 Ti.
