docker stats sums CPU across every logical processor, so Jellyfin's "227%" is
2.3 threads busy — 7% of a 32-thread host, which is what Unraid shows and what
the operator was reading. The card was printing the raw figure and colouring it
against thresholds meant for a percentage, so ordinary background work looked
like an emergency; I twice flagged Jellyfin as pegged on that basis and was
wrong both times. Divides by nproc, not the watchdog's `cores` — that field is
the physical 16 because it compares load averages, and borrowing it here would
have looked reasonable and doubled every reading.
