--- type: reference title: Observability Provisioning description: "Monitoring config as code: the config triad, deploy copiers, planner mappings, and where each change type lands." tags: [observability, prometheus, grafana, provisioning, deployment] timestamp: 2026-10-05T00:00:00-07:00 --- # Observability Provisioning The monitoring stack is **provisioned as code**: dashboards, datasources, scrape jobs and alert rules live in the repo and ride the normal deploy flow. No hand-edits inside containers — they are wiped on recreate and never committed. ## The config triad | Repo path | What it holds | |---|---| | `shared/prometheus/prometheus.yml` | scrape jobs (global + per-host) | | `shared/prometheus/rules/llm-fleet.yml` | alert rules + recording rules | | `shared/grafana/provisioning/` | datasources + dashboards (provisioned tree) | Targets and datasources reference **container names** (`grafana:3000` `loki:3100` — `shared/prometheus/prometheus.yml:52-61`), never loopback-published ports; `alloy` is **not scraped at all** (no job in the config — its `127.0.0.1:12345` UI is only probed by the homepage timer, `shared/homepage/services.json:233`). The LLM endpoints split by topology: the two same-host ones (`frank-dragoon` `:7770`, `frank-zealot` `:7771`) are scraped as `host.containers.internal:` because a bridge container cannot reach a host-netns bind at the host's LAN IP (`prometheus.yml:89-99`), and only the endpoint on another machine (`192.168.0.235:7770`) is addressed by LAN IP (`prometheus.yml:128-131`). Prometheus 3 refuses HTML responses as metrics — HTML-scraped "probes" are structurally inert and need a blackbox exporter (see [[Stale Signal Audit]]). ## The deploy path `scripts/deploy-remote.sh` carries one copier per config surface, all called from `deploy_observability`: - `copy_prometheus_config` → `/opt/prometheus/config/prometheus.yml` **and** `config/rules/llm-fleet.yml` (`:219-227`) - `copy_alertmanager_config` → `/opt/alertmanager/config/alertmanager.yml` (`:232-235`) - `install_signal_relay` → the user unit + iptables + the health wait on `192.168.0.143:18093/health` (`:243-274`) - `copy_loki_config` → `/opt/loki/config/loki-config.yaml` (`:276-279`) - `copy_alloy_config` → `/opt/alloy/config/config.alloy` (`:281-284`) - `copy_grafana_provisioning` → `/opt/grafana/provisioning/` (`:286-300`) `scripts/deploy-plan.py` maps `shared/prometheus/**` to `prometheus` (plus `alertmanager` when the changed file is `alertmanager.yml`, `:251-256`) `shared/loki/**` to `loki` and `shared/alloy/**` to `alloy` (`:257-260`), and `shared/grafana/**` to `grafana` (`:261-264`); changes under `dankclaw/observability/` select the touched unit and its dependency consumer (`:321-328`), and a change to either relay file redeploys `alertmanager` (`:399-402`). So `deploy.sh dankclaw --service grafana` (etc.) restarts only what the change touched. Seam tests in `tests/observability_quadlet.bats` pin the unit files exist and are boot-persistent/self-healing (`:36-62`), that no unit publishes on a wildcard (`:63-81`), that the copiers install each unit (`:250`), that grafana provisioning is declared in git and installed (`:345`), and that the provisioned paths match the units' mounts. ## Entry points **Add a scrape target** — edit `shared/prometheus/prometheus.yml`. Decide the vantage first: container name if the exporter is a container on `dankclaw_default`; `host.containers.internal:` if it is a process in the host's own network namespace **on this same machine** (a bridge container cannot reach the host's LAN IP at an unpublished port); the host's LAN IP only if it is a process on a **different** machine; a blackbox module if it is an HTTP probe, not a metrics endpoint. **Add an alert/recording rule** — edit `shared/prometheus/rules/llm-fleet.yml`. Current delivered set: **4 alert rules + 2 recording rules** — `LlmRequestsQueueing`, `LlmPrefixCacheCollapse`, `LlmSpecDecodeOff` `LlmEndpointDown`, plus `job:llm_prefix_cache_reuse:rate5m` and `job:llm_spec_accept_length:rate5m` (`shared/prometheus/rules/llm-fleet.yml:32-110`) confirmed live: `curl -s http://127.0.0.1:9090/api/v1/rules` (2026-10-18) reports 4 alerting + 2 recording. Rules reload with the prometheus service. **Add a datasource** — drop a YAML file into `shared/grafana/provisioning/datasources/`. Point it at the container name of the backend (`http://prometheus:9090`), not loopback. **Add a dashboard** — drop the JSON into `shared/grafana/provisioning/dashboards/`. Provisioned dashboards live in unified storage, not (only) the SQLite table — grep the API, not the DB, when verifying (see the verify section of [[Fleet Audit and Posture]]). *(unverified 2026-10-18: the storage-backend claim needs an admin password to confirm against `grafana.db` and the API side by side)* ## Verify through the APIs, not the filesystem ```bash # prometheus: rules and targets actually loaded curl -s http://127.0.0.1:9090/api/v1/rules | python3 -m json.tool | head curl -s "http://127.0.0.1:9090/api/v1/targets?state=active" | \ python3 -c "import json,sys; [print(t['labels'].get('job'), t['health'], (t['lastError'] or '')[:60]) for t in json.load(sys.stdin)['data']['activeTargets']]" # grafana: datasource + dashboard provisioned curl -s -u admin: http://127.0.0.1:3002/api/datasources | python3 -m json.tool | grep -E '"name"|"url"' ``` The two Prometheus queries were run on 2026-10-18 and are what every number on this page comes from: 4 alerting + 2 recording rules, and `up` for `prometheus`, `node-dankclaw`, `node-dankserver`, `grafana`, `loki` `frank-zealot`, `frank-dragoon`, `frank-archon` with the four structural downs listed in [[Prometheus]]. The Grafana query needs the local admin password and was not run here; the filesystem side (`ls /opt/grafana/provisioning/*`) is proof of installation only — see the next paragraph. Health answers from a stale process and provisioned resources can hide in unified storage — a file existing on disk is not proof the running server loaded it. See [[Stale Signal Audit]] for the never-green-target decision table (refused = outage, 404/HTML = config defect). ## 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. ## Related - [[Observability]] — stack topology and the alert delivery chain - [[Stale Signal Audit]] — classifying down targets before "fixing" them - [[Quadlet Lifecycle]] — the units that host these services - [[Deploy State Triage]] — how the planner selects these services
