klv-system-monitor 0.1.1

Cross-platform-ish system monitor (tested on Linux & Windows). Clean PyQt UI for CPU, memory, network and filesystems.

KLV-System-Monitor

KLV System Monitor is a lightweight, cross-platform system monitoring tool written in Python with PyQt5 and psutil. It provides a modern, customizable interface inspired by the Ubuntu system monitor, while adding advanced features for efficiency, flexibility, and user control.

CPU usage can be visualized in three modes—Multi thread, General view, and Multi window—selectable from the Preferences dialog.

Plots adapt to the selected theme. "Multi window" graphs show axes without tick labels and overlay each core's usage, number, and optional frequency atop its panel. The Preferences dialog exposes controls for mini-plot size, column count, a single-color option for all cores, and separate EMA alphas for CPU, memory, and network graphs. CPU plots can optionally be filled with translucent color, and network smoothing can be toggled independently.

Recent updates further reduce the monitor's own CPU usage by batching per-process information retrieval, decoupling plot and text refresh rates, and refreshing the file system view only on demand. Graph antialiasing is enabled again for crisp rendering and can now be toggled in Preferences. The Processes tab now updates only when visible, and its refresh interval is configurable via the Preferences dialog.

The Processes tab also includes buttons to clear the current selection so the view stops following a particular process and to kill selected processes.
