Looking for a system monitor, task manager, and service manager app for your Linux Desktop? Try Mission Center!

It’s a free open-source application written in Rust programming language, and uses GTK4 + LibAdwaita for its modern user interface that’s well integrated into Ubuntu, Fedora Workstation, and other Linux with GNOME Desktop.

With it, you have a Windows Task Manager look like interface that can monitor your CPU, Memory, Disk, Network and GPU usage with graphs.

Mission Center

As you can see in the screenshot above, the app has a left side-bar that displays the basic system resource usage with small graphs with brief description texts.

In right, the Performance tab shows more detailed information about system resource usage, including:

• • CPU utilization (overall & per-core), real-time speed, processes, threads, handles, and basic CPU info, such as its name, base speed, L1/L2/L3 cache size, and driver.
  • Memory usage – how much in use, cached, swap in use, and basic memory info, such as speed, type (e.g., DDR4, DDR5), and how many slots in use.
  • GPU (experimental) with video encoder / decoder usage, memory usage and power consumption, with the power of NVTOP.
  • Disk utilization, real-time read, write speed, capacity, and type (NVMe or HHD).
  • Network utilization, upload/download speed, ip4/ip6, and Mac address.

The Apps tab lists all the running apps and background processes, with their PID, and how much CPU, RAM, Disk, GPU each process consume.

By right-clicking on an app or process in the list, it shows the options to stop (send close signal) or force stop (kill) the app or process.

The Services tab, shows all the process in your system, either in active running or not. Each has Start, Stop, Restart buttons, as well as Details with few more information.

The feature is available since version 0.5.0, however not complete. So far, it does not support sorting by clicking on column header.

The app also has limitations, including no per-process network usage, lack VRAM, power, or temperature monitoring for Intel GPU monitoring. Though, it’s still in active development to overcome them and add new features.
