Multi-featured system monitor

Translations: Chinese (Simplified) | Chinese (Traditional) | Czech | German | English | French | Hungarian | Persian | Polish | Portuguese (Brazilian) | Portuguese (Portugal) | Russian | Spanish | Turkish | Notes for translators

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)
  • Install from Ubuntu Private Archive: Add the Launchpad PPA

    sudo add-apt-repository ppa:mamolinux/gui-apps
    sudo apt update
    sudo apt install leaptime-manager

  • Running from source code:
    • Use the test script at the root of the repository.

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.

For Developers

I am managing these apps all by myself during my free time. There are times when I can't contribute for months. So a little help is always welcome. If you want to test System Monitoring Center,

1. Get the source package and unzip it using:

   wget https://github.com/mamolinux/system-monitoring-center/archive/refs/heads/master.zip
   unzip master.zip
   cd system-monitoring-center-master

2. Make desired modifications.
3. Manually install using meson:

   rm -rf builddir
   meson setup -Dprefix=$HOME/.local builddir
   meson compile -C builddir --verbose
   meson install -C builddir

   It will install all files under /home/<yourusername>/.local. To remove the locally (/home/<yourusername>/.local) installed files, run:

   ninja uninstall -C builddir

4. Test it by running in debug mode from terminal:

   /home/<yourusername>/.local/bin/system-monitoring-center
