Switching from Microsoft Windows? You’ll be familiar with this new system monitor application for Linux!
It’s Mission Center, a free and open-source tool written in Rust programming language. And, it uses GTK4 plus LibAdwaita for its user interface that automatically changes UI color depends on system color scheme.
As you can see in the screenshot, it has a ‘Performance‘ tab that looks quite similar to the one in Microsoft Windows 10’s task manager.
Which, has a brief system load info in the left pane, that displays CPU usage and speed, Memory size and how much in use, disk usage, network speed, GPU usage and temperature.
And, it shows you real-time charts, along with system process, thread, and handle count, uptime, cache sizes, OpenGL/Vulkan versions, etc info in the right. At the moment of writing, the GPU monitoring supports only AMD and NVIDIA graphics card.
The real-time charts can be displayed in summary mode. Rather than double-clicking on it, user can right-click on any area in the right, and choose “Graph Summary View”.
Mission Center as well has a ‘Apps‘ tab that monitors user opened applications as well as background running services. Though, it so far lacks ability to kill processes and monitor network usage in per-process.
In Windows 10, I prefer to double click in left pane. So, it will display a summary view of all resources like the screenshot below shows. Sadly, the app does not support this function at the moment of writing.
