How to install and get the most out of Mission Center on Linux

Today, Linux users have a wide variety of system monitoring applications at their disposal, but not all of them offer a modern visual experience, integration with the latest desktop environments, or advanced features tailored to today's needs. Among the most notable alternatives in recent years are Mission Center, a tool that has been gaining popularity for its visual approach, active development, and for providing a comprehensive view of all system resources, from the CPU to the GPU, and even service management, in a simple and efficient manner.

Mission Center It represents a breath of fresh air for those looking for a complete and modern system monitor in GNU/Linux environments, especially for users of GNOME and distributions based on Ubuntu, Fedora, Debian and others. In addition, its ease of installation through Flatpak or AppImage, together with the continuous arrival of new features thanks to its active community of developers, make it an increasingly recommendable option for both advanced users and those coming from Windows and want a powerful alternative to the classic Task Manager.

What is Mission Center and why does it stand out?

Mission Center is a open source desktop application developed mainly in Peace and based on the graphic library GTK4/libadwaita. Its objective is to offer detailed and real-time monitoring of the main components of hardware and system processes, with an intuitive and aesthetically pleasing interface. It has earned a prominent place among Linux users thanks to its unifies in a single window information that would normally be scattered across different areas apps or would only be accessible from the console.

The main features that have driven its popularity include the ability to view the usage of CPU, RAM and swap memory, disks, network, GPU and, since its latest versions, also the monitoring of Fans and the management of system services compatible (Systemd and OpenRC). It also allows you to drill down into each resource, view statistics broken down by process or application, and perform quick actions such as stopping processes that are consuming too many resources, all from a user-friendly, visual interface.

Key Features and Functionalities

• CPU Monitoring: Allows you to view global or detailed usage by thread, with information about the model, current and base speed, caches, number of active processes, and usage time.
• RAM and Swap memory: Provides a clear view of how system memory is allocated and used. Includes real-time graphs and a breakdown by usage type.
• Discs and storage: Reports disk usage, read/write rates, connected devices (SATA, NVMe, USB, optical discs), and even displays SMART data to detect potential problems with hard drives and SSDs.
• Network monitoring: Details both overall network usage and transfer speeds on each interface (e.g., Wi-Fi or Ethernet), showing names, connection type, address MAC, IP, and advanced statistics. It's possible to view network usage by process, thanks to integration with solutions like Nethogs.
• GPU: While it's often difficult to find clear information about graphics card usage on Linux, Mission Center solves this problem by integrating the NVTOP library to monitor overall usage, video encoding/decoding, memory consumption, and GPU power. It supports a wide range of GPUs, including Intel Broadwell and later, some AMD cards, NVIDIA and even Raspberry Pi.
• Fans and sensors: In recent versions (since 0.6.0) there is support for monitoring fan speeds, PWM (pulse width modulation) and temperatures, helping to keep hardware health under control.
• Service Management: If your system uses Systemd or OpenRC, Mission Center allows you to view the status of services, start, stop, or restart, as well as query logs and individual details, offering simple management without depending on the terminal.
• Lists of processes and actions: Displays all active processes, with their PID, CPU, memory and disk usage, allowing you to select and stop any process from the graphical interface.
• Customizable charts and visual summary: Charts can be configured to display data in greater or lesser detail, adjust the refresh rate, summarize information in compact modes, and display statistics in full screen.
• usability and design: It has buttons and keyboard shortcuts, consistent sidebar across devices, support for customizing units of measurement, and a highly polished visual experience fully adapted to modern GNOME standards.
• Translations and communityMission Center has translations into Spanish, Catalan, French, Italian, Japanese, Galician, German, and many other languages, with ongoing updates contributed by the community.

Recent improvements and evolution of Mission Center

Over the past few months, Mission Center has received a large number of improvements in performance, stability and functionalityAmong the most important changes are:

• Monitoring backend renewal (Magpie: formerly Gatherer), now even available as a standalone library for other tools.
• Interface improvements: New app page design, memory view optimization, much smoother graphics, and improved sidebar.
• Handling removable devices: It is now possible to eject discs and USB devices directly from the application.
• Reduced memory and CPU usage: Insecure code fragments have been removed, update cycles have been optimized, and overall interface responsiveness has been improved to avoid penalizing system performance.
• Troubleshooting common bugs: Fixed memory leaks, crashes in some service managers, errors when copying large files, and other hardware- or distribution-specific issues.
• Extending GPU and Sensor Support: Supported GPU models and fan monitoring have been expanded to more platforms.
• AppImage SupportIn addition to Flatpak, Mission Center is now distributed in a portable AppImage format, making it easy to port and use on any distribution without additional dependencies.

Known limitations and aspects to take into account

While Mission Center is close to perfect for many users, it still has some acknowledged limitations, such as the partial support for some Intel GPUs (Broadwell only or later, no VRAM, power, or temperature monitoring), or the Limited integration with Linux Mint Cinnamon (some released applications do not appear correctly in the list), issues that are already on the project roadmap to be resolved in future versions.

Likewise, some features may not be enabled if compatibility with specific hardware is not detected, but the community is quite active in reporting suggestions and fixes.

Installing Mission Center on Linux

One of the strengths of Mission Center is its simplicity of installation, thanks to the preference for Flatpak and the availability of AppImage. This means it can be installed not only on Ubuntu, Fedora, Debian, or Arch Linux, but on virtually any modern distribution.

Installation using Flatpak

To install Mission Center via Flatpak, simply make sure you have Flatpak and the Flathub repository enabled. On most distributions, simply run the following commands: commands In the terminal:

sudo apt install flatpak flatpak remote-add --if-not-exists flathub https://flathub.org/repo/flathub.flatpakrepo flatpak install flathub io.missioncenter.MissionCenter

Once installed, the application will appear in the usual applications menu. If you prefer to run it from the terminal, you can launch it with:

flatpak run io.missioncenter.MissionCenter

Installation with AppImage

If you prefer not to rely on Flatpak, you can download the latest version in AppImage format from the GitLab releases page. Once you have downloaded the file (e.g. MissionCenter-x86_64.AppImage), you just need to give it execution permissions:

chmod +x MissionCenter-x86_64.AppImage ./MissionCenter-x86_64.AppImage

This allows you to run Mission Center on any Linux machine without installing anything and without taking up extra space with dependencies. Ideal if you're looking for portability or using Live environments.
