How it works — CPU
  • Read /proc/stat twice, compute deltas to find busy vs idle time.
  • CPU% = (delta_busy / delta_total) * 100 — computed for aggregate and per-core.
  • Render per-core ASCII bars + aggregate %, plus load averages for context.
  • Sampling interval configurable via the controller (e.g., 1s, 2s, 5s).
  • Top CPU-consuming processes can be listed using ps -eo pid,user,%cpu,%mem,comm.
