=============================================================================== LinuxDoors System Status — for the LinuxDoors AppImage Store =============================================================================== Name: LinuxDoors System Status Price: $0.00 Maker: LinuxDoors.com Created: September 12, 2026 Kind: A LinuxDoors AppImage Software Product File: LinuxDoorsSystemStatus.AppImage Size: 417M (single file, download and run) SHA256: b2877dfc06a02e7f0b529cde0932d1c3cbf7ae8fe4067c21b5605335a05c1f56 CARD DESCRIPTION (the one line the store shows under the name) A professional, WCAG-checked system monitor — CPU, memory, disks, live network connections, and process control in one window. ------------------------------------------------------------------------------- DESCRIPTION ------------------------------------------------------------------------------- A system monitor built to look and feel like part of LinuxDoors itself, rather than a utility borrowed from somewhere else. It watches the machine the way the built-in tools of a well-finished desktop do: per-core CPU load, memory and swap, how full each mounted disk is, what the network is actually doing right now, and which processes are running — with the ability to act on any of that, not just look at it. A Summary tab shows every area at once, each with its own fold toggle so a section can be tucked away without losing it — folded sections keep updating underneath, so opening one again never shows a stale reading. Prefer more room for one thing at a time? Dedicated CPU, Memory, File Systems, Network, and Processes tabs each get the whole window, reading the same live data as the Summary view. Written for LinuxDoors, though nothing in it is specific to LinuxDoors — it runs on Debian and Ubuntu type systems, and on any other Linux distribution that can run an AppImage. ------------------------------------------------------------------------------- What is in the program ------------------------------------------------------------------------------- CPU Every core shown as its own live bar, sized to however many cores the machine actually has, plus an overall-usage line chart scrolling in real time. Numbers come straight from /proc/stat — the same source top itself reads — not a guess or an average smoothed past recognition. MEMORY RAM and swap, each as a bar with the real figures beside it (used and total), and a scrolling chart of RAM usage over time. Read from /proc/meminfo directly. FILE SYSTEMS A table of every real mounted filesystem — device, mount point, size, used, free, and percentage — read from /proc/mounts and statvfs(), with no guessing at what "real" means: pseudo-filesystems are left out. NETWORK A scrolling chart of upload and download throughput sits above a live connections table: protocol, local and remote address, state, and the process that owns each connection. The table comes from ss, the process list from ps — both well-tested tools already on any real Linux system, rather than a hand-rolled reimplementation of a kernel interface. PROCESSES A full, sortable process table — PID, user, CPU, memory, priority, command. Select a process to end it or change its scheduling priority; if the action needs a password, the program asks for one rather than failing silently. LIGHT AND DARK, MEASURED NOT GUESSED Opens in light mode by default, with a one-click switch to dark. Both themes are checked against the real WCAG 2.1 contrast-ratio formula before shipping — every text and background pairing in the interface, including chart labels and grid lines — rather than judged by eye. A self-test (--check-contrast) reports any failing pair; there are none. ZOOM A single +/- control scales the whole interface's base font size, so the window stays legible and proportional at a larger size rather than one panel growing while the rest stays put. ------------------------------------------------------------------------------- Verified across every LinuxDoors desktop ------------------------------------------------------------------------------- LinuxDoors offers a choice of desktop environments, each with its own window manager, and this program was checked under all seven rather than assumed to work everywhere because it worked somewhere: XFCE, MATE, GNOME, Cinnamon, KDE Plasma, LXQt, and Enlightenment. It launches cleanly and renders correctly under each. ------------------------------------------------------------------------------- Why 417M for a program this small ------------------------------------------------------------------------------- The program itself is one Python file of about 45 kilobytes. Everything else in the download is the machinery carried alongside it so the file runs on its own, on a machine that may have none of the following already installed, or a different version of any of them: - Its own copy of Python 3, complete with the standard library, since the AppImage cannot assume the host has Python installed at all. - Its own copy of the Qt 6 toolkit (the parts this program actually uses: the core, the windowing and widget libraries, and the charting library for the live graphs) plus PySide6, the layer that lets the Python code drive Qt. Qt's own graphics, font and text libraries come with it, since they are not optional parts of Qt — they are how it draws anything at all. - Its own copy of glibc, the C library and dynamic loader every one of the above is built on. This is what lets the same file run correctly whether the host is running an older or a newer C library than the one it was built against — the file does not have to match the host's version, because it never uses the host's copy. None of this is unused padding: it is the complete, working set of libraries the interface is drawn with, compressed as tightly as the format allows (zstd at its highest setting). A distribution's own package manager would install most of this once and share it between many programs; a single portable file cannot do that, so it brings its own copy of everything it needs instead. This is the same reason every other self-contained Qt-based AppImage in the LinuxDoors Store — GIMP, OpenShot, LinuxUltraOffice — lands in a broadly similar size range: the floor is set by the toolkit each one carries, not by how much of that program's own code there is. ------------------------------------------------------------------------------- What it does not do, plainly ------------------------------------------------------------------------------- It is better to know the edges of a program before downloading it. - No historical logging. Charts scroll a recent live window; nothing is written to disk for later review. - No remote monitoring. It watches the machine it runs on, not another one over the network. - No alerting or thresholds. It shows what is happening; deciding whether a number is a problem is left to you. ------------------------------------------------------------------------------- LinuxDoors original ------------------------------------------------------------------------------- Built by LinuxDoors.com — this is our own application, not a mirror and not a repackaging of somebody else's build. The SHA-256 above is authoritative. It carries its own Python 3, its own Qt 6, and its own glibc, so it does not depend on the host's Python or Qt version, or its C library. Nothing is installed on the machine and nothing on the machine is disturbed. ------------------------------------------------------------------------------- Running it — nothing to install ------------------------------------------------------------------------------- chmod +x LinuxDoorsSystemStatus.AppImage ./LinuxDoorsSystemStatus.AppImage On LinuxDoors, which has no FUSE, run it the way LinuxDoors runs any AppImage: ./LinuxDoorsSystemStatus.AppImage --appimage-extract-and-run or through linuxdoors-run-appimage, which does that for you and unpacks it once rather than on every launch. The first launch is slower while it extracts; later launches from the same extracted copy are fast.
