GNOME System Monitor review
A focused Linux desktop monitor for processes, resource usage, and routine troubleshooting.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
GNOME System Monitor is an open-source Linux desktop utility for viewing running programs and monitoring system resources. It is suited to Linux desktop users who need a visual view of processor, memory, swap, disk, filesystem, and network activity, along with basic process management. Its graphs show recent usage information, while process and filesystem views support routine monitoring and troubleshooting.
The utility’s main strength is the breadth of its runtime views in one desktop interface. Users can inspect running programs and processes, review CPU and memory usage, examine disk and filesystem use, and view network activity and speed. Process controls include force-stopping unresponsive programs and changing process priority. For deeper investigation, it can show open files and the processes using them, as well as process memory maps. Command-line tools can provide comparable information, giving Linux users another path to the same general monitoring scope.
GNOME System Monitor is a focused choice rather than a complete system-information suite. Its documented scope centers on active processes and resource usage, so it fits users troubleshooting performance or checking current desktop activity more closely than users seeking broad hardware, firmware, BIOS, or installed-software inventories. The published product model is open source, and its operating-system scope is Linux. Pick it for accessible desktop monitoring and process control on Linux; choose an alternative when you need wider system inventory coverage or a multi-platform tool.
