Rust tools to monitor GPU stats on Linux

Tools

This repository has the 2 main tools below that share the internal qmlib library.

qmassa! - TUI tool to display GPU usage stats qmassa

qmassa

qmmd! - Prometheus HTTP endpoint to export GPU usage metrics qmmd

Below is an example of the metrics exported by qmmd.
