Roadmap

• [x] CPU usage
• [x] Memory usage (RAM and swap)
• [x] Network chart (upload/download)
• [x] Disk chart (write/read)
• [ ] GPU VRAM chart (help needed)
• [x] Displayed charts config
• [x] Sampling configs
• [x] Chart theming
• [ ] Vertical charts (for left/right panels)
• [ ] Popup (general system info)

Configuring

You can configure the charts displayed by editing ~/.config/cosmic/dev.DBrox.CosmicSystemMonitor/v1/charts. Only charts in this config will be displayed. VRAM will be ignored until it is implemented.

The fields update_interval, samples and size are the sampling time in milliseconds, the total number of samples displayed and the size relative to the panel height (top/bottom panels), respectively.

You can use colors defined in CosmicPaletteInner, as well as rgb("") with a hexcode.

Example config where the CPU, RAM, Swap, Net and Disk charts are displayed, in this order:

[
    CPU((
        update_interval: 1000,
        samples: 60,
        size: 1.5,
        color: accent_blue,
    )),
    RAM((
        update_interval: 2000,
        samples: 30,
        size: 1.5,
        color: accent_green,
    )),
    Swap((
        update_interval: 5000,
        samples: 12,
        size: 1.5,
        color: accent_purple,
    )),
     Net((
         update_interval: 1000,
         samples: 60,
         size: 1.5,
         color_up: accent_yellow,
         color_down: accent_red,
     )),
     Disk((
         update_interval: 2000,
         samples: 30,
         color_read: accent_orange,
         color_write: accent_pink,
         size: 1.5,
     )),
    // VRAM((
    //     update_interval: 1000,
    //     samples: 60,
    //     color: accent_indigo,
    //     size: 1.5,
    // )),
]

Special Thanks

• paradoxxxzero for their GNOME Shell system monitor extension, the inspiration for this applet
• edfloreshz for the template for COSMIC applets, which taught me the logic behind an applet
• aschiavon91 for their initial work at a system status applet, which was used as a reference implementation
• Joylei for implementing an Iced backend for plotters, used at the core of this applet
