The flood tail decays over roughly twenty hops in bars under a pixel
tall. Buckets holding less than 0.1% of the series are no longer drawn,
which on the live mesh takes the axis from 64 buckets to 44.
What is left out is reported, not dropped: a line under the chart reads
"1,467 further flood packets (0.9%) sit in 20 hop buckets below 0.1%
each, and are not drawn." An unannounced cut would be the same lie as a
silently truncated category list.
Two details that matter for honesty:
Percentages still divide by the whole series, never by the drawn subset,
so removing the tail cannot inflate the bars that remain. The smallest
surviving bar on live data is 0.118%, which is what it was before.
A withheld bucket inside the axis is null rather than zero. Zero would
claim no packets travelled that far, which is a different and false
statement; null draws nothing and says nothing. Padding gaps stay zero,
because there it is true.
The threshold applies to the flood series only — the node series is
small enough to draw in full — and the underlying computation still
covers the whole 64-hop protocol range.
Three layout and cost changes.
Hops away and Roles now grow into their cards instead of leaving dead
space under a fixed-height canvas. Chart.js needs a positioned parent
with a real height, so the body becomes a flex column and the chart takes
the slack via flex-basis 0 — height: 100% would resolve against an
auto-height parent and collapse.
The hop axis now ends at the last hop that carries an observation rather
than at the last non-empty bucket of the padded union. On a quiet window
that collapses 64 buckets to 13; on a full one it changes nothing,
because the flood series really does have packets at every hop out to 63
— 14 of them at hop 63, and 14.1% of all flood traffic beyond hop 20.
That tail is real data, so it is drawn rather than truncated.
Dropped the Live Activity card. It opened three SocketIO subscriptions
and re-rendered on every packet to duplicate /realtime, which is a page
that already does it better. The dashboard now costs one snapshot read
per poll and holds no streaming subscriptions. A test asserts it stays
that way rather than merely that the markup is gone.
MeshCore carries up to a 64-byte path, so a route can be 64 hops long at
one byte per hop — and proportionally fewer with 2- or 3-byte hashes,
which is where the observed ceilings of 32 and 21 come from.
The chart capped at 32. That number was inherited from the old
dashboard's `BETWEEN 0 AND 32` filters and carried forward without
checking it against the protocol. On the live database it silently
discarded 5,654 flood packets arriving from as far as 63 hops.
Worse for the node series: the cap runs after the per-node MIN(), so a
node whose *closest* route exceeded 32 hops disappeared from the chart
altogether instead of appearing at the far end. The live history holds
one such node, reachable only by a 48-hop path.
The axis can now span 64 grouped categories, so bars drop their rounded
corners and padding above 24 buckets and the x ticks auto-skip. 64 is
kept as a hard ceiling: beyond it the path field could not have held the
route, so the value is corrupt rather than distant.
Keeps the advert series — nodes by their closest observed path — and
adds arriving flood packets by how far they had already travelled.
The two answer different questions and, on the live mesh, disagree
usefully: nodes peak at 2-3 hops and fall away quickly, while flood
traffic peaks at 5 and holds a long tail past 16. A close-in
neighbourhood absorbing flood from well beyond it.
One series counts nodes (2.8k) and the other packets (156k), so raw
counts on a shared axis would flatten the node series into the baseline.
Both are drawn as a share of their own total, with absolute counts in
the tooltip, and padded onto one contiguous hop range so the bars line
up. They also cover different spans — 7 days of adverts against
whatever packet_stream retains — so each is labelled with its own
window instead of being presented as one period.
Watch the units. observed_paths.path_length is a BYTE count, so hops are
path_length / bytes_per_hop. packet_stream.path_len is already a HOP
count, with the byte length carried separately as path_byte_length. A
17-hop 3-byte path is path_length 51 in one table and path_len 17 in the
other. Applying either rule to the other silently rescales the axis and
the only symptom is a chart that looks a bit off, so both conventions
are now pinned by tests against the shapes real rows take.
Flood packets carry no sender identity and observed_paths holds only
adverts, so the flood series cannot be reduced to a shortest path per
node the way the advert series is. It is a per-packet distribution, and
the tooltip says so.
Moving the hop histogram out into its own card left the routing mix as a
26px bar alone in a col-lg-5, next to a full-height chart. Fill it with
something that belongs there: what the traffic is, beside how it is
routed, over exactly the same packets — the totals agree because both
read the dimensioned rows.
This also gives payload_type_name a reason to exist. Migration 0019
added the column, integration.py writes it at capture time, the
refresher backfills it and an index covers it, and until now nothing
read it.
Category lists now roll their tail into "Other" instead of being
truncated at eight rows in the client. Silently dropping the tail left
bars that no longer summed to the total printed beside them; on the live
database that would have hidden 1,015 packets across four payload types.
307 direct neighbours was not plausible, and it was not real.
complete_contact_tracking.hop_count claims 800 zero-hop contacts. Only
68 of them have any one-hop path in observed_paths to corroborate that.
Their stored SNR piles up in a 1.5 dB band — 655 of 800 between 11.25
and 12.75 dB — and their RSSI clusters at -39..-48 dBm. Hundreds of
radios at different distances and terrain cannot land in a 10 dB window.
That is the signature of one strong local link being recorded against
every node whose traffic happened to arrive through it. Their return
paths agree: these "direct" contacts have out_path_len of 3 to 11.
The writer's intent is sound — repeater_manager only stores RSSI/SNR
when signal_info reports hops == 0 — so the field being fed to it does
not mean what the surrounding code assumes. Left as is; this change
stops the dashboard depending on it.
Neighbour membership now comes from path evidence: an advert whose
path_length equals its bytes_per_hop travelled exactly one hop. That
yields 38 nodes in 24h and 124 in 7d, with a plausible spread. Signal is
shown only where the path evidence and the stored hop count agree, which
is 5 and 12 nodes respectively; the rest read "no signal reading" rather
than borrowing a measurement taken on somebody else's link. A 24h/7d
selector bounds the window, capped well under observed_paths' 90-day
retention because a month-old link says nothing about today.
Separately, this fixes a bug I introduced. path_length is a BYTE count,
and with 2- or 3-byte hop encoding a 3-hop path is 6 or 9 bytes long. The
path-length histogram plotted that raw value on an axis readers would
take as hops, overstating distance two- to threefold on a mesh that is
~95% multibyte. It is replaced by a single hops-away chart computed as
path_length / bytes_per_hop, which also retires the histogram built on
the untrustworthy stored hop count. The result is unimodal, peaking at 3
hops and decaying — the shape a mesh should have, and not the bimodal
one the old chart drew.
Three adjustments from review.
Role and device type are the same field twice. Measured on the live
database they disagree on 16 of 11,028 contacts (ten roomservers and a
handful of bots and gateways reporting device Companion); every other
row is repeater/Repeater, companion/Companion, type11/Type11 and so on.
Charting both filled half a card with a copy of the other half. Keep the
role mix, which also carries the type0..type15 bucketing, and move it
into the routing row where the old signal card was.
Drop the tracked-contacts tile. is_currently_tracked does not describe
anything a reader can act on, and node activity is already covered by
nodes-heard and gone-quiet. The known-contacts total moves onto the
coverage tile, which leaves five tiles splitting the row evenly.
Rebuild the signal panel around zero-hop neighbours. Percentiles over
every received message answered no question anyone has: SNR on a relayed
packet measures the last hop into this radio, not the link to the node
that sent it, so averaging across hop counts describes nothing in
particular.
The panel now shows the nodes heard with no repeater in between — how
many, their SNR distribution, and the weakest links named, worst first,
on a fixed -12..+14 dB scale so bars mean the same thing between
refreshes. On the live database that is 307 neighbours, median 12.0 dB,
with eight marginal links surfaced from -9.0 dB down.
This also corrects the source. The plan rejected
complete_contact_tracking.snr as a badly biased 7% sample; in fact it is
populated on exactly the 800 hop_count=0 contacts and NULL on all 10,228
others. It is not a sample of the network, it is a complete census of
the neighbours — which is precisely the population the metric applies
to. message_stats.hops=0 covers only 34 senders by comparison.
The landing page re-ran ~50 aggregate queries five times per load, then
repeated the whole sequence every 30 seconds forever — including in
backgrounded tabs. Against the live 1.44 GB database that was roughly 20
seconds of SQLite work per page load.
Move the work off the request path. A refresher thread in the viewer
process (which already runs migrations, so it works for a split-DB
install) writes two tables: daily_rollup, one row per local date, and
dashboard_snapshot, a single JSON row. A page load now reads one row.
Measured on the live database: first paint 6 requests -> 2,
/api/dashboard/summary p50 1.1 ms (304 in 0.8 ms), /api/stats 130 ms,
and a 0.32 s refresh once a minute in the background.
Make the numbers mean what they say:
- Window selectors are built from each source's retention. The page
offered "30d" and "All" against tables pruned at 7 days, so three of
four choices returned the same figure under a label that denied it.
- The incoming-packet chart reports its measured window instead of
claiming 7 days for a table pruned at 3 — it sat beside a genuine
7-day contacts chart inviting an invalid comparison.
- Days with no source data store NULL and render as gaps. Writing 0
would put a fake cliff at every retention boundary.
- Signal metrics are stored as sums and counts, never means, so any
window re-aggregates correctly.
- Delta chips compare the last two complete calendar days and say so;
the headline above them is a rolling 24 hours.
- Unmapped role ordinals (type0..type15) bucket into "Unknown".
- SNR comes from message_stats, where it is populated on every row, not
from complete_contact_tracking, where it is populated on 7%.
Kill the json_extract scans: packet_stream gains denormalized
route_type_name, payload_type_name, path_len and bytes_per_hop, written
at capture time. Aggregating those from JSON cost 3-6 s per query.
Existing rows convert a bounded batch per tick rather than in one
migration that would rewrite ~180 MB into the WAL and stall bot startup.
A partial index serves as the backfill worklist — without it the "any
rows left?" probe is a full scan costing 4.6 s per tick, and it costs
that after the backfill finishes, because finding nothing still means
reading everything.
Also: replace the per-contact hop-prefix scan with the existing bucketed
matcher and memoize the 7-day chunk set (264 ms -> 35 ms on a synthetic
100k-row database, regression-locked by a test); move the dashboard's JS
and CSS to static files, which removes the CSP nonce requirement for the
bulk of the page; and give cleanup_old_stats a future-timestamp guard,
without which rows dated 2103 are never older than the cutoff and so
live forever.
Deletes the orphaned /stats page, unreachable from the nav and rendering
stub charts that never populated. /api/stats stays as a shim with every
key name intact plus Deprecation and Sunset headers.
All schema changes are additive, so a downgraded codebase can read the
data; it would however need the new schema_version rows removed, since
MigrationRunner rejects versions it does not know.
