* This commit adds error checking to prevent desklet or Cinnamon crashes
when any of the used files are absent from the system, most often
because the system doesn't have a gpu from AMD.
It also switches amdgpu functions to use async function calls for
file reading, like the rest of the desklet.

System monitor graph Desklet
Desklet to show graphs for the level of activity in various system variables including: CPU, memory, 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 (v1.3 - April 2022)
| 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 % |
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
Settings for one instance of the system monitor graph Desklet.
Screenshots
The Desklet is fully customizable.
A simple screenshot.
TODO
- Add other variables such as network, CPU and GPU temperatures, battery levels for PC and peripherals.
