Desklet to show graphs for the level of activity in various system variables including: CPU, memory, network and disks. The desklet supports multiple instances with different system variables with the idea of presenting them in a uniform way.

Four instances of the Desklet in action.

This project has been inspired from other Desklets such as Disk Space, CPU Load, Simple system monitor, Network usage monitor, Top, and the Rainmeter Win10 Widgets.

Features

Variables to monitor (v2.0 - July 2025)

System variable	Description
CPU	CPU usage in %
RAM	Used RAM as % of total, and in GB
Swap	Used Swap space as % of total, and in GB
HDD	% of I/O activity, and free and total space in the filesystem (partition) indicated by the user
GPU Usage	GPU usage in %
GPU Memory	GPU memory usage in %
Network	Real-time upload and download speeds with dual-line graph, configurable interface monitoring

Each variable is calculated every Refresh interval seconds (Min. 1 s, Max. 60 s.), and the graph shows the last Duration of the graph period (Min. 30 s, Max. 60 min).

Customizable visual elements
