Features:

• Detailed system performance and usage usage monitoring/managing features:
  • Monitoring CPU, RAM, Disk, Network, GPU hardware/usage information
  • Monitoring and managing processes and services (systemd)
  • Monitoring users, sensors and general system information
• Supports PolicyKit. No need to run the application with "sudo"
• Hardware selection options (selecting CPU cores, disks, network cards, GPUs)
• Plotting performance data of multiple devices at the same time
• Interactive charts for querying performance data on any point
• Option for showing processes as tree or list
• Optimized for low CPU usage
• Customization menus for almost all tabs
• Supports ARM architecture
• Hardware accelerated GUI
• Free and open source

Installation:

• There are several options for using System Monitoring Center:
  • Installing from Flatpak (Details)
  • Installing from application stores (Pardus Application Center, Pi-Apps Store)
  • Installing from repositories of distributions
  • Installing from PyPI as a Python package. There will be no new packages on PyPI (Details)
  • Running from source code:
    • For SMC v2: in src/ folder, run: python3 ./run_from_source.py
    • For SMC v1: in src/ folder, run: python3 ./Main.py

Dependencies

There is no need to install these dependencies for installing the application from Flatpak. For other installation types:

• For System Monitoring Center v2.x.x:

  • dmidecode, gir1.2-adw-1, gir1.2-glib-2.0, gir1.2-gtk-4.0, gir1.2-pango-1.0, hwdata, iproute2, python3 (>=3.6), python3-cairo, python3-gi, python3-gi-cairo, util-linux (>=2.31)

• For System Monitoring Center v1.x.x:

  • dmidecode, hwdata, iproute2, procps (>=3.3), python3 (>=3.6), python3-cairo, python3-gi, python3-gi-cairo, util-linux (>=2.31)

• Following dependencies may be required on some systems:

  • libcairo2-dev (for systems with .deb packages)
  • polkit (for Arch Linux)

• Optional dependencies:

  • vcgencmd (for physical RAM size, GPU frequency and video memory information on Raspberry Pi devices)
  • x11-xserver-utils or xorg-xrandr (for more accurate screen resolution and refresh rate detection of System Monitoring Center v1.x.x)

Limitations and Known Issues:

Show

Limitations

• GPU usage information availability depends on vendor/driver.
• GPU load is not tracked if GPU tab is switched off (for lower CPU usage).
• Virtual machines may not provide CPU min-max frequencies, sensors and RAM hardware information.
• Non-Flatpak versions of the application has higher performance (start speed, CPU, RAM usage).
• GTK4 (used for SMC v2) consumes about 2x RAM when compared to GTK3 (used for SMC v1).
• Running SMC v1 after SMC v2 resets application settings

Known Issues

• Expander/Collapser arrows do not work sometimes if processes are listes as tree (Processes tab). Issue

• Tab customization menus are not closed when clicked outside of the popover menu after using a dropdown menu on the popover menu.

  • This is a GTK4 bug. These menus can be closed by using Esc key.
