DarkMatter Software / Linux System Intelligence
Total visibility. Total control.
The original DarkMatter system monitor has evolved into a full native PySide6 command center. Watch the machine breathe in real time, inspect its processes, map its storage, profile its hardware, archive its state, and export the evidence.
Two Proven Editions
SysMon 3.0 is the major visual and functional upgrade. SysMon 1.0 remains available as the compact, dependable Go/Fyne original for users who prefer the earlier native build.
A full-scale Python and PySide6 system intelligence environment with animated telemetry, richer analytics, process and storage workspaces, profile collection, automation, alerts, multiple visual themes, system tray support, and an expanded export pipeline.
The original Go/Fyne release remains a fast, stable, and compact system monitor. It preserves the proven earlier interface and monitoring engine without the expanded workspaces introduced in version 3.0.
A Living View of Linux
SysMon 3.0 organizes live metrics, deep inspection, historical activity, and system state into a single native desktop interface built to remain useful while it looks alive.
Rolling CPU and memory graphs, per-core activity, load averages, swap pressure, threads, and throughput.
Search, sort, inspect, and manage active processes without abandoning the main monitoring environment.
Filesystem capacity, mounted devices, usage pressure, disk operations, and live read/write activity.
Interface inventory, traffic rates, connection visibility, and rolling upload and download history.
Collect Linux, kernel, CPU, memory, storage, service, network, hardware, and optional security intelligence.
Capture system states, attach profile data, preserve notes, and export records for later comparison.
Automate snapshot intervals and define warning thresholds for CPU, memory, and disk pressure.
Move telemetry and collected intelligence into JSON, CSV, HTML, or text reports.
Interface Architecture
Every workspace has a defined job. Overview summarizes the host, Performance exposes pressure, Storage and Network reveal movement, and System Profile drills below the surface.
Major Version Upgrade
Version 3.0 does not erase the original. It takes the same system-awareness mission and expands it into a broader, more visual, more configurable desktop environment.
Go + Fyne / Classic
Python + PySide6 / Current
Source Edition
SysMon 3.0 uses a local Python virtual environment so its PySide6 and psutil dependencies stay contained beside the application.
Linux desktop, Python 3.10 or newer, and pip. Elevated permissions are optional and are only relevant to profile probes that Linux restricts for ordinary users.
# Enter the extracted SysMon directory
$ cd SysMon_PySide6_3.0
# Create and activate an isolated environment
$ python3 -m venv .venv
$ source .venv/bin/activate
# Install the native GUI and telemetry dependencies
$ pip install -r requirements.txt
# Launch the control center
$ python sysmon.pyDarkMatter Software Release 3.0
Keep the lean Go/Fyne original or step into the full PySide6 command center. Both editions remain available from the official SysMon release archive.
