* **A target can read down beside a healthy service.** Read `lastError` from
`/api/v1/targets` before believing an outage — llama.cpp refuses `/metrics` at the
protocol layer without `--metrics` (501) while `/health` answers 200 for weeks.
* **Alert state lives where the tool says it does.** Prometheus keeps rule state in
process memory — a restart re-stamps `activeAt`, so a "fresh" alert after a reboot is
not evidence of a fresh fault. Alertmanager **does** persist (`--storage.path` on a
host volume: silences + notification log, [[Alertmanager]]).
* **Never quote a candidate arm's flags or VRAM as fleet state.** A stopped production
unit (`failed` after `stop-sigterm timed out. Killing` — the known shutdown shape,
[[frank-zealot]]) beside an answering port means the metric measured a scratch boot;
the process shape can change between two censuses ten minutes apart.

## Current delivered state (delivery chain live 2026-09-17, re-verified 2026-10-18)
Prometheus → Alertmanager (`dankclaw/observability/quadlet/alertmanager.container`
loopback `:9093`) → host-side Signal relay (`scripts/signal-relay.py`, user
unit, `192.168.0.143:18093` — the LAN IP, the one bind a container can reach
via `host.containers.internal`) → signal-cli, addressed by number
`+12062476336` (`scripts/signal-relay.py:36-43`). Every hop re-checked
2026-10-18: `ss -ltnp` shows `python3` on `192.168.0.143:18093`
`curl -s http://192.168.0.143:18093/health` → `ok`, and
`journalctl --user -u signal-relay` ends with successful `sent to +12062476336:`
lines for `LlmEndpointDown`, `LlmRequestsQueueing`, `LlmSpecDecodeOff` and
`LlmPrefixCacheCollapse` (firing and resolved). Some targets read down for
structural reasons (HTML-scraped "probes", Gitea metrics off); the remedy is
the blackbox exporter. See [[Prometheus]] → Targets.
**A llama.cpp endpoint is invisible unless it opts in.** Until 2026-10-18,
`up{job="frank-zealot"}` was 0 for the entire retained history of the metric —
the oldest sample, 2026-10-11, is already 0 — while the service itself answered
`/health` 200 the whole time. Cause: llama.cpp only exports `/metrics` when it
is started with the flag, so the scrape was refused at the protocol layer (the
flag and its opt-out are on [[frank-zealot]]) and `LlmEndpointDown` (critical)
stayed firing:
the relay re-sent it on the 4 h `repeat_interval` for days (`journalctl --user
-u signal-relay` — firing sends at 01:37, 05:42, 09:47, 13:52, 17:57 and 22:02
on 2026-10-12). It finally resolved at `2026-10-18T01:53:21-07:00`, after the
metrics opt-in landed that day; the target
reports up since (`curl -s http://127.0.0.1:9090/api/v1/targets` 2026-10-18).
How many payload generations it spanned is not readable from any host
artifact. *(unverified 2026-10-18)*
Two laws fall out of it. A target can read down beside a healthy service, so
read `lastError` from `/api/v1/targets` before believing an outage. And rule
state lives in Prometheus' process, not on disk — a restart re-stamps
`activeAt` on a long-standing alert, so a "fresh" alert after a reboot is not
evidence of a fresh fault. (Alertmanager by contrast **does** persist:
`--storage.path=/alertmanager` on a host volume keeps silences and the
notification log — `dankclaw/observability/quadlet/alertmanager.container:39-42`
`/opt/alertmanager/data`.)
Remaining known downs are the structural ones above (HTML-scraped probes, Gitea
metrics, ComfyUI), and `frank-dragoon` exports `/metrics` natively
([[frank-dragoon]]), which is why
`frank-dragoon` has always been green. The active-alert count is a
moment-in-time value and should never be documented as a constant:
`/api/v1/alerts` was empty at the 2026-10-18 morning census, held one firing
`LlmPrefixCacheCollapse` (`activeAt` 11:10:48Z, value 2.6e-4) when sampled
minutes later, and was empty again by 11:56Z; the relay logged the matching
firing and resolved sends at `04:26:21-07:00` and `04:41:21-07:00`.
**What that zealot scrape measured on 2026-10-18.** As of ~04:30 PDT the
production `frank-zealot` root unit was stopped **on purpose** for a benchmark
window on the 3090 — the repo Benchmarking Policy says stop the production
service before benching — and `:7771` answered from a manually booted candidate
arm (`systemctl is-active frank-zealot` → `failed` after
`stop-sigterm timed out. Killing`, which is llama.cpp ignoring SIGTERM past
`TimeoutStopSec`, the known shutdown shape for these engines). So
`up{job="frank-zealot"} == 1` that day measured the trial, not the production
shape in `scripts/frank-zealot.env` — that shape is [[frank-zealot]]'s to state,
and it is the repo contract.
The unit stayed `enabled`; `./scripts/deploy.sh dankclaw --service frank-zealot`
reinstalls and starts it, restoring boot persistence and self-healing. Never
quote a candidate arm's flags or VRAM as fleet state — the process and its shape
changed between two censuses ten minutes apart.
