The builder pushes its build metrics (builds by kind and outcome, build
duration, queue depth and wait, reply publish failures) to its forwarder's
OTLP receiver, which relays them to the swarm collector.
It also registers the standard store client-certificate gauges
(bao.client_cert.*, cert=builder) on the same exporter. They are the
builder's liveness signal: exported every minute whether or not a build
runs. The cert-metrics table in docs/scheduler/observability.md gains the
builder row.
The per-agent /stats page read these from its sqlite; the swarm board had
none of them. hive-agent now counts the tools a turn called, the commands
bash tasks ran (from the bash daemon's own table, newer rows only),
reminders scheduled and delivered, and records the first turn of a fresh
session; the turns tab shows them, with fresh sessions per agent. Claude's
own export has no tool-call counter, so the docs no longer say it does.
The ST4TS page (/stats.html), GET /api/stats-hive, hive-c0re's hive_stats
rollup and the modelPrices option that only fed its cost estimate are
gone. Each agent's own /stats page and the turn-stats database it reads
are unchanged. Setting modelPrices now fails evaluation with a message
saying so.
The per-agent /stats page shows what the swarm agents board lacked about
turns. The new tab reads the turn count and duration the harness already
records: average duration, cache hit rate, tokens per turn, turns per hour
by agent and by model, duration percentiles, and the wake source and result
mixes. The duration histogram used the SDK default buckets, which stop at
10 s while a turn averages 24 s, so every p95 read a flat 10 s; it now has
explicit bounds up to an hour.
U+2692 is text-presentation by default, so it drew as a small
monochrome glyph next to the colour icons of the other links. The
hammer is emoji-presentation by default.
A builds tab (counts, failures, longest, builds over time by outcome, a table of
each build) and an output tab (every line of the build picked in the Build
filter). The table joins its grouped stats by labels, one row per build.
