.gitignore, old/scripts/*, dankclaw/comfyui/*, and report/* per this repo's
own convention ('add one before committing'). Obsidian wikilinks are

# Grafana
|
|
|
|
Grafana visualizes the metrics that Prometheus collects from every service. It runs on Dankclaw and is reachable at `grafana.franksdank.cloud` (via Caddy, with basicauth).
|
|
|
|
**Host:** Dankclaw — **Hostname:** `grafana.franksdank.cloud` — **Port:** 3002 (internal) — **Docs:** https://grafana.com/docs
|
|

## Facts

| Item | Value |
|

|
|
| Image | `docker.io/grafana/grafana:latest` |
|
|
| Port | 3002 (host) → 3000 (container) |
|
|
| Data volume | dashboards, users, datasource config |
|
|
| Datasource | Prometheus (on the same host) |
|
|
| Provisioning | dashboards in `/etc/grafana/provisioning/dashboards` |
|
|
|
|
## Configuration
|
|
|
|
```yaml
|
|
environment:
|
|
GF_SECURITY_ADMIN_USER: "${GRAFANA_ADMIN_USER}"
|
|
GF_SECURITY_ADMIN_PASSWORD: "${GRAFANA_ADMIN_PASSWORD}"
|
|
GF_SERVER_ROOT_URL: "https://grafana.franksdank.cloud"
|
|
volumes:
|
|
- /opt/grafana/data:/var/lib/grafana
|
|
- /opt/grafana/provisioning:/etc/grafana/provisioning:ro
|
|
```
|
|
|
|
## Datasource
|
|
|
|
Point Grafana at the Prometheus service by name (`http://prometheus:9090`) on the shared podman network.
|
|
|
|
## Healthcheck
|
|
|
|
Grafana responds on `/api/health` with 200 and `"database":"ok"`.
|
|
|
|
## Gotchas
|
|
|
|
- Change the default admin credentials at first boot (env or UI).
|
|
- Dashboards provisioned as YAML survive container recreation; UI-created ones live in the data volume — back it up.
