A process and system monitoring library for Rust, heavily inspired by the psutil module for Python.

Add this to your Cargo.toml:

[dependencies]
psutil = "4.0.0"

Or to only use certain submodules:

[dependencies]
psutil = { version = "4.0.0", default-features = false, features = ["cpu", "process"] }

This project is not well maintained, and there are a host of other projects that may meet your needs better. rust-psutil started as a university student's project before the Rust 1.0 release (all the way back in January 2015!), and has had irregular maintenance by a small group of developers since then.

There's no intent to archive it any time soon, as there are still projects using rust-psutil and we get the occasional pull request to implement a new feature. Open a discussion if you'd be interested in helping maintain it, ideally after you've made one or two contributions.

See "Related Projects" below for a list of projects that overlap with rust-psutil's functionality. Hiem has a comparison between Rust libraries with similar functionality: https://github.com/heim-rs/heim/blob/master/COMPARISON.md.

The API is relatively unstable. The version number attempts to follow semantic versioning, and you should major version bumps to include multiple breaking changes—most significant new features added to rust-psutil required adjusting existing APIs.

Currently, only Linux and macOS are supported at all.
