Multi-featured system monitor

*** Announcement (31.10.2023): End of support for System Monitoring Center ***

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

Notes for 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).

Notes for Flatpak Support:

• Flatpak version of the application uses some permissions (like not sandboxed) to access performance/system information of the host OS.
• Flatpak package of the application may be installed for system-wide instead of user-specific for avoiding source code modifications.
