# 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
```
