Nvidia System Management Interface (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.

Global configuration options

In addition to the plugin-specific configuration settings, plugins support additional global and plugin configuration settings. These settings are used to modify metrics, tags, and field or create aliases and configure ordering, etc. See the CONFIGURATION.md for more details.

Startup error behavior options

In addition to the plugin-specific and global configuration settings the plugin supports options for specifying the behavior when experiencing startup errors using the startup_error_behavior setting. Available values are:

  • error: Telegraf with stop and exit in case of startup errors. This is the default behavior.
  • ignore: Telegraf will ignore startup errors for this plugin and disables it but continues processing for all other plugins.
  • retry: NOT AVAILABLE

Configuration

# Pulls statistics from nvidia GPUs attached to the host
[[inputs.nvidia_smi]]
  ## Optional: path to nvidia-smi binary, defaults "/usr/bin/nvidia-smi"
  ## We will first try to locate the nvidia-smi binary with the explicitly specified value (or default value),
  ## if it is not found, we will try to locate it on PATH(exec.LookPath), if it is still not found, an error will be returned
  # bin_path = "/usr/bin/nvidia-smi"

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

Linux

On Linux, nvidia-smi is generally located at /usr/bin/nvidia-smi

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

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.

NOTE: For use with docker either generate your own custom docker image based on nvidia/cuda which also installs a telegraf package or use volume mount binding to inject the required binary into the docker container. In particular you will need to pass through the /dev/nvidia* devices, the nvidia-smi binary and the nvidia libraries. An minimal docker-compose example of how to do this is:

  telegraf:
    image: telegraf
    runtime: nvidia
    devices:
      - /dev/nvidiactl:/dev/nvidiactl
      - /dev/nvidia0:/dev/nvidia0
    volumes:
      - ./telegraf/etc/telegraf.conf:/etc/telegraf/telegraf.conf:ro
      - /usr/bin/nvidia-smi:/usr/bin/nvidia-smi:ro
      - /usr/lib/x86_64-linux-gnu/nvidia:/usr/lib/x86_64-linux-gnu/nvidia:ro
    environment:
      - LD_PRELOAD=/usr/lib/x86_64-linux-gnu/nvidia/current/libnvidia-ml.so
