How to watch every saved server's health on one page with Hatoba

See online status, CPU, memory, disks, and load for all saved hosts without installing anything on them.

Authorization notice. Hatoba is dual-use. Only use it on software, sites and systems you own or have explicit permission to test.

Who it is forA sysadmin or solo operator with several Linux servers who wants a quick health view before starting work.

The problemChecking each server one by one over SSH takes time, and installing monitoring agents on every machine is not always allowed.

The outcomeA dashboard of cards or a table showing the status of each saved host, read over SSH.

What you need first

  • A computer running Windows, Linux, or macOS (Windows is the maintainer's main platform)
  • Rust stable, Node.js 22 or later, and pnpm for building from source
  • WebView2 on Windows, Xcode Command Line Tools on macOS, or the Tauri system dependencies such as libwebkit2gtk-4.1-dev on Linux
  • SSH access to at least one host, with a password or key
  • A Cloudflare account for optional sync (the free plan usually covers personal use)
  • An API key from an OpenAI-compatible or Anthropic provider for the AI assistant

Steps

  1. Import your existing hosts from ~/.ssh/config, or add them in the Hosts view with groups and tags.
  2. Confirm each host's authentication method, such as a key in the Key vault or ssh-agent.
  3. Open the Dashboard and switch between the card and table views.
  4. Click a host to open a terminal session if a metric looks wrong.

Prompt for your agent

In the scarletkc/Hatoba app, open the Dashboard after importing hosts from ~/.ssh/config, then list each saved host with its online status and CPU and memory readings. Verify that every saved host appears once and that no software was installed on the servers.

Caveat. The README says the terminal status bar shows CPU, memory, and network for Linux servers, so the dashboard's full detail is most reliable on Linux hosts.
