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
• 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

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).

Known Issues

• Not detected so far.
