rbspy\n\n[![crates.io](https://badgen.net/crates/v/rbspy)](https://crates.io/crates/rbspy)\n[![ci](https://github.com/rbspy/rbspy/actions/workflows/ci.yml/badge.svg)](https://github.com/rbspy/rbspy/actions/workflows/ci.yml)\n\n\u003cimg src=\"https://rbspy.github.io/static/images/rbspy.jpg\" width=\"128px\"\u003e\n\nHave a running Ruby program that you want to profile without restarting it? Want to profile a Ruby\ncommand line program really easily? You want `rbspy`! rbspy can profile any Ruby program just by\nrunning 1 simple command.\n\n`rbspy` lets you profile Ruby processes that are already running. You give it a PID, and it starts\nprofiling. It's a sampling profiler, which means it's **low overhead** and **safe to run in\nproduction**.\n\n`rbspy` lets you record profiling data, save the raw profiling data to disk, and then analyze it in\na variety of different ways later on.\n\n## Documentation\n\n=\u003e https://rbspy.github.io\n\n## Requirements\n\nrbspy supports Linux\\*, Mac, Windows, and FreeBSD.\n\n\u003csmall\u003e\n* kernel version 3.2+ required. For Ubuntu, this means Ubuntu 12.04 or newer.\n\u003c/small\u003e\n\n## Add a testimonial\n\nDid rbspy help you make your program faster? An awesome way to thank the project is to add a [success story to this GitHub issue](https://github.com/rbspy/rbspy/issues/62)\nwhere people talk about ways rbspy has helped them! Hearing that rbspy is working for people is good\nmotivation :)\n\n## Installing\n\n### Standalone binary\n\nOn Mac, you can install with Homebrew: `brew install rbspy`.\n\nOn Linux:\n\n1. Download recent release of `rbspy` from [the GitHub releases page](https://github.com/rbspy/rbspy/releases).\n    * The binaries tagged with `musl` are statically linked against musl libc and can be used on most systems. The ones tagged with `gnu` are dynamically linked against GNU libc, so you will need it to be installed.\n2. Unpack it\n3. Move the `rbspy` binary to `/usr/local/bin`\n\nOr have a look at [Installing rbspy](https://rbspy.github.io/installing.html) on our documentation.\n\n### As a Rust library\n\nTo use rbspy in your Rust project, add the following to your Cargo.toml:\n\n```toml\n[dependencies]\nrbspy = \"0.8\"\n```\n\n**WARNING**: The rbspy crate's API is not stable yet. We will follow [semantic versioning](https://semver.org/) after rbspy reaches version 1.0.\n\n## Contributing\n\nPull requests that improve usability, fix bugs, or help rbspy support more operating systems are\nvery welcome. If you have a question, the best way to ask is to [create a GitHub issue](https://github.com/rbspy/rbspy/issues/new)!\n\nIf you're not a very experienced Rust programmer, you're very welcome to contribute. A major reason\nrbspy is written in Rust is that Rust is more approachable for beginners than C/C++.\nhttps://www.rust-lang.org/ has great resources for learning Rust.\n\n## Building rbspy\n\n1. Install cargo from [crates.io](https://crates.io/)\n1. `cargo build` to build\n1. `cargo test` to test\n\nThe built binary will end up at `target/debug/rbspy`\n","funding_links":[],"categories":["Rust","Profiler and Optimization","Performance tools","Uncategorized","Awesome Ruby CLIs","Ruby specific"],"sub_categories":["Uncategorized","Profiling"],"project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Frbspy%2Frbspy","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Frbspy%2Frbspy","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Frbspy%2Frbspy/lists"}
