System Monitor

Track processor utilization and memory consumption in real time with System Monitor, giving you an immediate view of how heavily the computer is working. Live CPU and RAM statistics are presented as interactive graphs, so changes in system performance are easy to follow as they happen. A built-in meter also shows internet upload and download speeds, making bandwidth activity visible alongside local resource usage.

The application is lightweight and responsive, with low CPU and memory overhead of its own. Its desktop interface is intended for instant checks during demanding workloads, troubleshooting, everyday performance observation, or monitoring network activity. Linux desktop users can use it to spot rising RAM consumption, sustained processor load, or changing transfer rates without relying on separate utilities.

Published by Warlord Softwares, System Monitor is open-source software for Linux, currently at version 2026.7.2. It requires Linux with snapd and runs on x86_64 (amd64) systems. This CPU-temperature connection is a specific consideration for users who want temperature information in addition to the application's CPU, memory, and internet-speed readings.
