Svasthya — System Health Monitor

Svasthya shows you what your machine is doing — CPU load, memory use, system uptime — in a live dashboard inside VS Code. It is handy when a build is crawling or the editor feels sluggish and you want to know whether it's your code, your machine, or something else eating the resources.

What it shows

All figures are read live from the operating system:

• CPU usage — overall load, sampled continuously
• Memory — used vs total, as a percentage and in absolute terms
• Load average — the system's 1 / 5 / 15-minute load
• Uptime — how long the machine has been running
• This process — VS Code's own memory footprint

Values are colour-coded (healthy / busy / stressed) so problems stand out at a glance.

Usage

The dashboard updates on its own while it's open, so you can watch usage climb during a heavy compile or test run.

How it works

Svasthya uses Node's built-in os module — totalmem, freemem, cpus, loadavg, uptime — plus process.memoryUsage() for VS Code's own footprint. CPU usage is computed by sampling the CPUs' idle-vs-busy time across an interval, the same way system monitors do. Nothing is estimated or faked.

Why it exists

Students on modest laptops often can't tell whether a slow build is normal or a sign their machine is overloaded. Svasthya makes the machine's state visible, so "why is this so slow?" has an answer you can see.
