How a 2GB Flash Drive Led Me to Rust, Linux Internals and eBPF

说明与用途

Pulse 是一个基于 Rust 的终端监控工具，读取 /proc 和 eBPF 数据，能够在仅使用 2 GB USB 驱动器的最小 Arch Linux 系统上深入分析系统运行情况。

问题

Need an operating system small enough to fit on a 2 GB flash drive and a tool to monitor system health on a minimal Linux installation.

结果

Pulse provides a lightweight, terminal‑based observability dashboard that reads raw kernel data via /proc and eBPF, enabling deep insight into system performance and events on a minimal Arch Linux setup.

工作流

• 1. Factory‑reset laptop and remove Windows.
• 2. Install Arch Linux from ISO, partition disk, configure minimal system.
• 3. Use top/htop to view basic metrics.
• 4. Identify need for custom monitoring tool.
• 5. Design Pulse to read /proc for metrics.
• 6. Implement Rust TUI to display metrics.
• 7. Extend Pulse to use eBPF for kernel‑level events.
• 8. Iterate on Pulse features and learning objectives.

证据

Pulse is a Linux observability TUI written in Rust.

来源

Pulse reads information from /proc and turns raw data into metrics.

来源

eBPF lets you run small programs in the Linux kernel to observe and respond to events.
