COSMIC Vitals

A minimal applet to display basic system resource usage, i.e. CPU, Memory, Network.

I started building this to learn some Rust and play around with Pop_OS COSMIC. It's definitely a WIP but works pretty well for my needs. Hopefully the code will be useful to somebody else fighting with iced/libcosmic, etc.

Features

• Show CPU Usage
• Show RAM Usage
• Show Network upload / download. This filters out virtual devices so won't count upload / download twice when using a VPN, etc.
• Show Disk upload / down. This counts reads / writes to logical disks, not partitions, etc.
• Things that can be configured:
  • Read Intervals - How often each monitor is polled
  • Max Samples - The number of samples to keep to average the readings across
  • Show / Hide each monitor

Things I might fix

• Calculate the maximum width of the labels so the indicators don't expand / contract
• Improve the vertical layout
• Dynamically colour the icons based on the theme accent colours
• Add configurable units KiBs/MiBs/GiBs or progressively change units depending on how large / small reading is
• Better logging into journalctl
