ProfServe - HTTP-Enabled Profiling for Rust

ProfServe is a Rust crate that provides HTTP endpoints for performance profiling, built on top of pprof-rs. It enables remote profiling capabilities for your Rust applications with flamegraph generation and pprof data export.

Features

• 🚀 HTTP API for remote profiling
• 🔥 Flamegraph generation in SVG format
• 🔒 Async-ready for modern Rust applications

Quick Start

Installation

Add to your Cargo.toml:

[dependencies]
profserve = "0.1"

Basic Usage

fn main() {
    std::thread::spawn(|| profserve::http::serve(8080).expect("Failed to start profserve"));
    // your code goes here
}

Making Requests

Get a 10-second profile as flamegraph:

curl -s "http://localhost:8080/prof/cpu?seconds=10&frequency=100&output=flamegraph" > profile.svg

Get raw text pprof data:

curl -s "http://localhost:8080/prof/cpu?seconds=10&output=text" > profile.txt
