About Mission Center

Monitor your CPU, Memory, Disk, Network and GPU usage, accompanied by a per app and process breakdown of these statistics

Features:

• Monitor overall or per-thread CPU usage

• See system process, thread, and handle count, uptime, clock speed (base and current), cache sizes

• Monitor RAM and Swap usage

• See a breakdown how the memory is being used by the system

• Monitor Disk utilization and transfer rates

• Monitor network utilization and transfer speeds

• See network interface information such as network card name, connection type (Wi-Fi or Ethernet),
wireless speeds and frequency, hardware address, IP address

• Monitor overall GPU usage, video encoder and decoder usage, memory usage and power consumption, powered
by the popular NVTOP project

• Monitor system fans

• See a breakdown of resource usage by app and process

• Supports a minified summary view for simple monitoring

• Use hardware accelerated rendering for all the graphs in an effort to reduce CPU and overall resource
usage

• Uses GTK4 and Libadwaita

• Written in Rust

Limitations (there is ongoing work to overcome all of these):

• Intel GPU monitoring is only supported for Broadwell and later GPUs; and does not support VRAM, power,
or temperature monitoring

• When using Linux Mint/Cinnamon, launched applications may not show up in the "Applications" section
(Upstream issue: [link removed])

Release info New Release on Jul 23, 2026
Release notes Noteworthy changes:

• Add a new Battery page to the Performance tab, with charge graphs and detailed battery information (@jlo62)

• Show per-partition usage details on the disk page, including used and free space (@jojo2357)

• Overhaul the graphing backend: smoother animations and rendering, a new loading shimmer while data loads, and less stuttering on application startup (@jojo2357, @kicsyromy)

• Improve application detection, fixing wrong names and icons, phantom entries for PWAs, and constantly cycling processes (@kicsyromy)

• Improvements to the Snap package, which was upgraded to the core24 snap (@kicsyromy)

• Improvements to the AppImage package which now uses quick-sharun, is smaller and no longer depends on FUSE (@kicsyromy)

Minor features:

• Add a second CPU graph that can show temperature, power draw or CPU frequency (@jlo62)

• Add memory compression (zRAM/zswap) statistics to the Memory page (@timatgca)

• Refactor and redesign the Preferences dialog (@kicsyromy)

• Allow disabling entire device categories and individual network types (@kicsyromy)

• Update to GNOME 50 Platform (@kicsyromy)

• Pause UI refreshes by holding the CTRL key, just like the Windows Task Manager (@jlo62)

• More accurate per-process memory usage using a hybrid PSS approximation (@kicsyromy)

• Show per-process swap usage instead of shared memory in the Apps page (@jlo62)

• Allow sending process signals that require elevation via `pkexec` (@jojo2357)

• Add an option to select what the middle GPU graph displays (@jlo62)

• Add a first run dialog and setup script for advanced features (@jlo62)

• Add `--app-id`/`-a` command-line flag for setting custom application IDs (@kicsyromy)

• Collapse and expand rows using double-click or the left and right arrow keys (@jojo2357)

• Display the network connection state in the network details sidebar (@jojo2357)

• Show total GPU memory on the graph when GTT is not available (@jlo62)

• Add an option to gray out zero values in…
