# Nvidia GPU monitoring with Netdata
Monitors performance metrics (memory usage, fan speed, pcie bandwidth utilization, temperature, etc.) using `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.
- If `nvidia-smi` process [is not killed after netdata restart](https://github.com/netdata/netdata/issues/7143) you need to off `loop_mode`.
- `poll_seconds` is how often in seconds the tool is polled for as an integer.
## Charts
It produces the following charts:
- PCI Express Bandwidth Utilization in `KiB/s`
- Fan Speed in `percentage`
- GPU Utilization in `percentage`
- Memory Bandwidth Utilization in `percentage`
- Encoder/Decoder Utilization in `percentage`
- Memory Usage in `MiB`
- Temperature in `celsius`
- Clock Frequencies in `MHz`
- Power Utilization in `Watts`
- Memory Used by Each Process in `MiB`
- Memory Used by Each User in `MiB`
- Number of User on GPU in `num`
## Configuration
Edit the `python.d/nvidia_smi.conf` configuration file using `edit-config` from the Netdata [config
directory](/docs/configure/nodes.md), which is typically at `/etc/netdata`.
```bash
cd /etc/netdata # Replace this path with your Netdata config directory, if different
sudo ./edit-config python.d/nvidia_smi.conf
```
Sample:
```yaml
loop_mode : yes
poll_seconds : 1
exclude_zero_memory_users : yes
```
