What it does

DSH Web system status overlay: real-time CPU/memory/disk usage

✅
Our take
Works — verified, early-stage project

DSH Web system status overlay: real-time CPU/memory/disk usage It installs cleanly and boots without issues in our testing. It's early-stage but functional.

“Verified” means our automated CI actually ran dsh plugin add in a clean profile and it booted — nothing more. Feature descriptions and version compatibility are the author’s claims. This is not a security audit and not an endorsement of third-party code.

README

dsh-sysmon

DSH Web 的系统状态悬浮窗:固定在页面右下角,每 1 秒刷新显示 CPU、内存、磁盘占用率。

CPU 39%/16    MEM 46%    DISK 22%

显示规格

  • 位置:右下角固定悬浮,pointer-events: none,不遮挡界面操作。
  • 配色:默认浅灰色小字(等宽字体、11px)。
  • 刷新:1 秒一次。

阈值规则

指标 默认(浅灰) 橙色 红色
CPU(x%/y) < 90%×核心数 x ≥ 90%×核心数 x ≥ 98%×核心数
内存 ≤ 80% > 80% > 90%
磁盘 ≤ 80% > 80% > 90%
  • CPU:x% 为所有核心使用率之和(可超过 100%),y 为总核心数;阈值按总容量比例计算。
  • 内存 / 磁盘:超过 80% 橙色、超过 90% 红色。

安装

从 GitHub 仓库安装:

dsh plugin --profile web add github:AKS1st/dsh-sysmon
dsh web

或 clone 到本地后从本地目录安装:

git clone https://github.com/AKS1st/dsh-sysmon.git
cd dsh-sysmon
npm install
npm run build
dsh plugin --profile web add .
dsh web

工作方式

  • Host(src/index.ts):ctx.effect 挂一个每秒运行的后台采样器,经 ctx.shell 采样(/proc/stat、nproc、/proc/meminfo、df -P /),把最新快照写入内存缓存。路由 GET /dsh-sysmon/api 只返回缓存(亚毫秒、零子进程开销),并拒绝非 GET 方法与跨源浏览器请求。CPU 使用率为相邻两次采样之间的增量(窗口约 1 秒),首次采样显示 0。
  • Client(src/client/index.ts):创建 #dsh-sysmon 固定定位元素,每 1 秒 fetch 一次路由,带 in-flight 守卫避免请求重叠;重绘只更新三个数值节点(diff 式)。纯 DOM 实现、零运行时依赖。

已知限制

  • 仅 Linux——宿主采集器读取 /proc/stat、/proc/meminfo 与 df;其他平台需要不同的采集器。
  • 仅根文件系统——磁盘占用只报告 /,按挂载点选择暂缓。
  • 采样窗口近似——CPU 百分比是相邻两次采样(约 1 秒)间隔内忙时占比,窗口内瞬时突发被平均。

Install

🧩 Let your agent install it (recommended)

Install the catalog once, then DeepSeek Harness can find and install any plugin from this site automatically:

dsh plugin add dshbase-catalog

Then say "install dsh-sysmon for me" — your agent finds it in the directory and installs it. Docs: dshbase-catalog · verified packs.

This plugin is GitHub source (not published to npm) — install it straight from the repo:

Web profile:

dsh plugin --profile web add github:AKS1st/dsh-sysmon

Headless (CLI) profile:

dsh plugin --profile headless add github:AKS1st/dsh-sysmon

Test report

Verified: L1 install + L2 load + L3 runtime from GitHub source on dsh 0.1.0-rc.6.

When to use it

Give the agent a memory, a knowledge base, or a retrieval layer so it stops forgetting context between sessions.

Who it's for

Users running long projects who want the agent to remember decisions, docs, and preferences without re-explaining.

For developers — extending it

The memory/retrieval backend is the seam — plug a new store, tune what gets distilled, or add citation and audit trails.

Security: not yet scanned — our daily static scan will cover it shortly.
