- Active jobs on /stats get a cancel button wired to the existing
download/match cancel endpoints, showing "cancelling..." and an inline
error when the task already finished.
- Cancelling now sets the status immediately, so a task whose runner died
in a restart stops showing as "downloading".
- Download streams use a bounded read timeout (10 s connect / 60 s read):
a stalled socket fails within a minute (previously it could block
forever), and a task cancelled while stalled is marked cancelled rather
than error.
- The stats job list reaps stale download/match tasks, so phantom jobs
never appear on the dashboard.
Backend: GET /api/stats/ (staff only) gathers psutil CPU/memory counters,
nvidia-smi GPU stats, the cached disk numbers and the running/finished
download + match jobs. Root logging now also writes a rotating file
(backend/logs/j621.log) so the dashboard can tail it, and psutil joins the
requirements. The storage payload computation is shared with the existing
storage endpoint.
Frontend: a /stats route + Stats nav entry for staff, polling every 2 s —
per-core CPU bars, memory and swap, GPUs (utilization, VRAM, temperature),
disk with the media/temp breakdown, active jobs with progress bars,
recently finished jobs with summaries, and the log tail with level colours
and an auto-scroll toggle. Section 4 of the roadmap is complete.
