# `nvidia-smi` Input Plugin
|
||
|
|
|
||
|
|
This plugin uses a query on the [`nvidia-smi`](https://developer.nvidia.com/nvidia-system-management-interface) binary to pull GPU stats including memory and GPU usage, temp and other.
|
||
|
|
|
||
|
|
### Configuration
|
||
|
|
|
||
|
|
```toml
|
||
|
|
# 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
|
||
|
|
```
|
||
|
|
|
||
|
|
### Metrics
|
||
|
|
- measurement: `nvidia_smi`
|
||
|
|
- tags
|
||
|
|
- `name` (type of GPU e.g. `GeForce GTX 170 Ti`)
|
||
|
|
- `compute_mode` (The compute mode of the GPU e.g. `Default`)
|
||
|
|
- `index` (The port index where the GPU is connected to the motherboard e.g. `1`)
|
||
|
|
- `pstate` (Overclocking state for the GPU e.g. `P0`)
|
||
|
|
- `uuid` (A unique identifier for the GPU e.g. `GPU-f9ba66fc-a7f5-94c5-da19-019ef2f9c665`)
|
||
|
|
- fields
|
||
|
|
- `fan_speed` (integer, percentage)
|
||
|
|
- `memory_free` (integer, KB)
|
||
|
|
- `memory_used` (integer, KB)
|
||
|
|
- `memory_total` (integer, KB)
|
||
|
|
- `temperature_gpu` (integer, degrees C)
|
||
|
|
- `utilization_gpu` (integer, percentage)
|
||
|
|
- `utilization_memory` (integer, percentage)
|
||
|
|
|
||
|
|
### 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"
|
||
|
|
```
|
||
|
|
|
||
|
|
