Required prerequisites

I have searched the Issue Tracker that this hasn't already been reported. (comment there if it has.)
I have tried the latest version of nvitop in a new isolated virtual environment.

Motivation

Can nvitop show pcie versions and Tx/Rx speed like nvtop, which is quite necessary for memory monitoring?

Solution

No response

Alternatives

No response

Additional context

No response

Hi @OutisLi, you can try nvitop-exporter with:

cd nvitop-exporter/grafana
docker compose up --build --detach

It provides TX/RX throughput for PCIe and NVLink.

@XuehaiPan commented on GitHub (Jul 30, 2025): Hi @OutisLi, you can try [`nvitop-exporter`](https://github.com/XuehaiPan/nvitop/tree/main/nvitop-exporter) with: ```bash cd nvitop-exporter/grafana docker compose up --build --detach ``` It provides TX/RX throughput for PCIe and NVLink.

You can set up your Grafana and Prometheus services manually without docker.

For example:

brew install grafana prometheus
vim "$(brew --prefix)/etc/prometheus.yml"
brew services start grafana
brew services start prometheus
uvx nvitop-exporter --bind-address 0.0.0.0 --port 5050

thanks, I'll look into this, since I just installed via pixi global install nvitop

BTW, you can monitor the per-process memory bandwidth utilization via %GMBW.

So I need to install grafana and prometheus to use this function? I cannot just install nvitop through pixi to use?

Then I installed nvitop-exporter, and run it using nvitop-exporter --bind-address 0.0.0.0 --port 5050. I configured a port redirecting to my laptop. There is just some texts on http://localhost:5050/metrics.

Can the Tx/Rx be shown in nvitop by just calling nvitop?

Thanks, but this is too complicated than just running nvitop or nvtop in ssh terminal considering that I need to configure port redirecting for the server (some may even need VPN). I'll probably turn to nvtop instead.
