# nvidia_smi
This module monitors the `nvidia-smi` cli tool.
**Requirements and Notes:**
- You must have the `nvidia-smi` tool installed and your NVIDIA GPU(s) must support the tool. Mostly the newer high end models used for AI / ML and Crypto or Pro range, read more about [nvidia_smi](https://developer.nvidia.com/nvidia-system-management-interface).
- You must enable this plugin as its disabled by default due to minor performance issues.
- On some systems when the GPU is idle the `nvidia-smi` tool unloads and there is added latency again when it is next queried. If you are running GPUs under constant workload this isn't likely to be an issue.
- Currently the `nvidia-smi` tool is being queried via cli. Updating the plugin to use the nvidia c/c++ API directly should resolve this issue. See discussion here: <https://github.com/netdata/netdata/pull/4357>
- Contributions are welcome.
- Make sure `netdata` user can execute `/usr/bin/nvidia-smi` or wherever your binary is.
- `poll_seconds` is how often in seconds the tool is polled for as an integer.
It produces:
1. Per GPU
- GPU utilization
- memory allocation
- memory utilization
- fan speed
- power usage
- temperature
- clock speed
- PCI bandwidth
## configuration
Sample:
```yaml
poll_seconds: 1
```
