The sensor feed dropped which socket a coretemp reading came from, so every core matched
the first CPU's chip. coretemp sensors now carry a package label, and history folding
keeps the two sockets' same-named cores apart.

Per-package RAPL watts in the sample, the process table and as cpu.package.N.power
sensors. The socket rows collapse with an arrow; the fold is remembered per browser.

Live from arcstats (dirty), dmu_tx (throttled writes), each pool's txgs (bytes synced to disk)
and objset kstats (bytes from programs). A landing tier — a mergerfs pool whose first branch is
fast storage and whose last is a ZFS dataset — is detected from mergerfs's branch xattr; a mover
status file in /run/landing-mover/ adds its queue, the file in flight and totals. Sensors
zfs.write.*, zfs.<pool>.write_bps|logical_bps and zfs.<pool>.landing.* carry the history.

New sensor cpu.power: watts from the RAPL energy counters (Intel, and AMD
Zen through the same driver), summed over every package and averaged into
history. Parts of a package, psys and the MMIO duplicate are left out.
The counters are root-only, so a daemon that isn't root reads them through
`hamlab cpu-energy`, a root helper started once with sudo or doas and asked
over a pipe each sample, the same shape as the GPU client walk's helper.
It reads only the counters it finds itself. No counters or no root means
no reading, and the CPU box shows nothing extra.

A Cache section between the pools and the schedules. One card for the ARC:
size against its ceiling with the target and floor, sparklines of size and
hit rate from the sampler's history, what it holds (MRU/MFU/dirty, data vs
metadata, compression, the ghost lists), the prefetcher and dbuf cache, the
memory-pressure counters, and the since-boot breakdown by demand/prefetch
and data/metadata. Then a card per pool for L2ARC, SLOG, special vdev,
dedup table and spares — the devices and their fill where they exist, and
where they don't, plainly none and what that means (the ZIL writing to the
pool's own vdevs, with how much it has written).
Live numbers come from the sampler, which reads arcstats every tick and
publishes zfs.arc.* sensors; the fuller picture is read on request, with
zpool list -Hpv and zfs get run without sudo and cached for thirty seconds.

Every DRM device with a real GPU driver gets a box under the cpu box, laid out
like it: the busy curve, a meter for the device and one per engine, temperature,
clock, power and fan where the card has them, and the processes holding it open
with their share. The process table gains a Gpu% column and sort.
Device busy is Intel's RC6 idle residency inverted (what intel_gpu_top shows,
and readable without root) or amdgpu's gpu_busy_percent. Per-process shares are
DRM fdinfo deltas, as nvtop reads them; other users' fdinfo needs root, so a
daemon running as a user keeps one root child (hamlab drm-clients) over a pipe
rather than paying a sudo a second. Everything is also a gpu.* sensor.
What cannot be measured is left out, not shown as zero: an Arc A380 on i915 6.12
has no temperature sensor, an integrated GPU wears the package temperature
marked *, and Asahi has neither a busy counter nor fdinfo yet.

Disks: one row per physical drive with its model, size, temperature and IO, and a usage
bar built from the filesystems the sampler can attribute to it. Attribution is new — a
mount's source device is resolved through sysfs to the drive behind it, following one
layer of device-mapper or md and folding NVMe namespaces the way the sampler does. A pool
member gets no usage bar, because one drive's share of a raidz pool is not a real number.
Net: every interface that is up is listed and tappable, defaulting to the one that has
actually carried traffic rather than whichever the kernel listed first.

core mounts grid's tank over CIFS, and it was listed beside root and efi as though it
were a disk in the box. Filesystems whose storage is on another machine are now marked
remote — a label on the fs sensors, so the sensor stays for anyone who wants it — and the
Processes tab's disks box leaves them out.

- stock Monitors modules fed by one sensor stream, the catalog and one batch of
histories (GET /api/sensors/history?ids=…), through sampleAdapter.ts
- the stream closes while the page is hidden and refills its curves on return
- Disks tab live rates from the stream
- new sensors: hamlab.sample_interval, ups.last_event
- stream: asking for about the sampling rate means every sample
- NUT runtime rounded at the source

Every number the collector samples becomes a sensor with a stable dotted ID
(cpu.core.3.usage, fan.nct6775.fan2, fs.root.used_pct). Clients discover them
from the catalog and ask for exactly what they want, including as a shaped
query: send the object you want, get it back with the values filled in.
