dsh-vitals

A DeepSeek Harness (dsh) Web-GUI plugin that shows live hardware load right in the web GUI — a self-contained, dependency-free companion to btop. Opens as a full tab next to Chat/Trajectory, or docked beside a session in the right sidebar.

What it shows

• CPU — overall utilisation, a live 60s sparkline, highest temperature reading, and per-core load (every physical core, any count) — with per-thermal-zone detail when there's more than one sensor
• Memory — used / available / total with utilisation %
• GPUs — one card each: name, temperature, utilisation, power draw, and VRAM (used / total)

Data is sampled host-side on every poll (~0.5 s) and rendered live.

How it works

• Host — a GET-only route registered on the dsh web server (/plugins/dsh-vitals/data) that reads the OS's own sources with no privileged access and returns JSON.
• Client — a single self-contained bundle that polls the route and draws the panels with inline styles (no CSS pipeline, no assets).

Where it shows up

Two access points, both live the moment the plugin is bundled — no setup:

• A full Hardware tab next to Chat / Trajectory at the top of the conversation view. The dedicated way to watch the box while you're not actively chatting.
• Docked in the right sidebar, alongside a session: open the right sidebar, click + (add tab), pick Hardware from the Guide list. Lets you chat and watch load at the same time. (Every dsh "page type" plugin opens this way — nothing dsh-vitals-specific about the click path.)

Platform support

Signal	Primary source	Fallback
CPU load	/proc/stat (Linux)	os.cpus() deltas (macOS / other)
Memory	/proc/meminfo (Linux)	os.totalmem() / os.freemem()
CPU temp	/sys/class/thermal	hidden when absent
GPUs	nvidia-smi (any count)	hidden when absent

Everything degrades gracefully: a missing source simply hides that panel or shows a placeholder rather than breaking the tab. Any number of GPUs is supported; any CPU (core count and vendor) is handled.

Install

From your dsh web profile (web below is the profile name; use whichever profile backs your web GUI):

dsh plugin --profile web add dsh-vitals

This installs the package into the profile and adds it to dsh.profile.bundles for you — no manual package.json editing. (No local dsh binary? Run the equivalent by hand from the profile directory, e.g. ~/.dsh/profiles/web/: pnpm add dsh-vitals, then add "dsh-vitals" to that package.json's dsh.profile.bundles array yourself.)

The published package ships its built lib/ output, so no build step runs on install — nothing else to do before restarting.

Restart your dsh web service and open the web GUI — see Where it shows up above for how to find it.

New bundles are registered from the profile's bundles array, so a one-time service restart is required the first time you add it.

Building from source

Requires Node 20+. Dependencies are dev-only (esbuild); the published package has zero runtime npm dependencies.

git clone https://github.com/JoblessJoe/dsh-vitals.git
cd dsh-vitals
pnpm install
node scripts/build.mjs     # emits lib/index.js + lib/client.js

package.json declares a build script, so pnpm build works too.

Configuration

None. The plugin reads whatever the host exposes; there is no config surface.

Security

The data route sits outside the dsh web server's /api trust fence, so it enforces that fence itself: Sec-Fetch-Site: cross-site requests are rejected (403) and only GET/HEAD are served (405 otherwise). All sources are read-only.
