Frank 8212d4451a docs: rename frank-default-large/small/sightsound to frank-large/small/npu across vault

Mechanical identity rename across the knowledge base, AGENTS.md, README, the
hermes config example, and homepage services.json. No behavior change; served
aliases on the LLM endpoints change with the deploy of commit 69f87c8.

Prometheus

Prometheus collects metrics from every service on Dankclaw by scraping their /metrics endpoints. It feeds the Grafana dashboards. The node-exporter containers may add podman/cgroup metrics for full host visibility.

Host: Dankclaw — Vhost: prometheus.franksdank.cloud (guarded: Anubis → Authentik; post-auth the Caddy vhost routes straight to prometheus:9090) — Port: 9090 — Docs: https://prometheus.io/docs

Facts

Item	Value
Image	`docker.io/prom/prometheus:latest`
Port	9090 (host) → 9090 (container)
Config	`/etc/prometheus/prometheus.yml` (bind mount)
Data volume	TSDB
Retention	`--storage.tsdb.retention.time=30d`

prometheus.yml Targets

scrape_configs:
  - job_name: "prometheus"
    static_configs:
      - targets: ["localhost:9090"]

  - job_name: "comfyui"
    static_configs:
      - targets: ["comfyui:8188"]

  - job_name: "node"
    static_configs:
      - targets: ["node-exporter:9100"]

Allow the /metrics endpoint on each service where the exporter exists. For services without a native exporter, use the Prometheus blackbox exporter (probe mode) to check up/down and latency.

Volumes

Container path	Host path (convention)
`/etc/prometheus`	`/opt/prometheus/config`
`/prometheus`	`/opt/prometheus/data`

Healthcheck

Prometheus responds on /-/healthy with 200.

Gotchas

Keep scrapes modest for a small homelab; too many targets bloat the TSDB.
Use recording rules for heavy queries (see Grafana).
Set a retention policy or the data volume grows without bound.
