Power Draw HUD is a live heads-up display of where your machine's power goes. A lightweight
Linux alternative to BatteryBar-style battery meters for watching real power draw.
Features:
- Live readouts from sysfs and /proc: battery charge/discharge watts, CPU package watts
(RAPL, when the kernel exposes it), CPU load, CPU frequency, disk and network throughput.
- Rolling 2-minute charts for power, load/temperature and I/O.
- Top Consumers: processes ranked by real CPU use with context-switch (wake-up) counts.
- Sensors tab: power supplies, RAPL domains and thermal zones.
- Optional always-on-top mode and CSV export of the session.
Sources that the hardware or kernel do not expose are shown as n/a, never invented.
