# 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
```
