vitals

Viewer for the CSV logs written by vitals-log (~/.local/bin/vitals-log, run every minute by the vitals-log.timer systemd user unit). Shows the latest reading and time-series plots of temperatures, battery, memory, memory pressure and load. Built with egui and egui_plot.

The log directory defaults to $XDG_STATE_HOME/vitals (~/.local/state/vitals). Every vitals-YYYY-MM.csv there is loaded at startup; after that only bytes appended since the last check are read (every 10 s by default). Columns are matched by header name, so a changed log layout shows gaps rather than breaking.

Drag to pan and ctrl-scroll or pinch to zoom the time axis; all plots move together. Picking a range preset returns to following the clock. Lines break where the logger was not running, and on-battery periods are shaded in the battery plot. Wide ranges are reduced to per-bucket min/max, so spikes stay visible.

• src/data.rs — parsed series, windowing, gap splitting, downsampling
• src/tail.rs — incremental file reader, month rollover, replaced-file reload
• src/main.rs — the UI; the PANELS table defines the plots
