---name: grafana-osslicense: Apache-2.0description: Configure Grafana OSS — provisions dashboards from YAML, sets up data sources (Prometheus / Loki / Tempo / Pyroscope), writes dashboard JSON with template variables, builds panel queries, assigns built-in roles (Viewer / Editor / Admin / GrafanaAdmin), mints service-account tokens, edits grafana.ini server config, creates annotations, installs plugins via provisioning, and validates each step with a health-check curl. Use when building dashboards, configuring data sources, setting up provisioning YAML, picking a panel type, writing template variables, managing users and roles, configuring SMTP/OAuth in grafana.ini, creating annotations via API, troubleshooting why a provisioned dashboard isn't showing up, or running Grafana OSS locally — even when the user says "set up a Prometheus data source", "provision dashboards from git", "make a service account", or "configure SSO in OSS" without saying "Grafana OSS".---

Common Workflows

Provisioning dashboards from disk

1. Drop dashboard JSON file(s) under /var/lib/grafana/dashboards/
2. Add a provider in provisioning/dashboards/default.yaml (see § Dashboard provisioning below)
3. Restart Grafana so the provider config is loaded
4. Verify the dashboard landed:

   curl https://grafana.example.com/api/dashboards/uid/<uid> \
     -H "Authorization: Bearer <token>" | jq '.dashboard.title'
   

   Returns the title → success. 404 → provisioning didn't pick it up; check Grafana server logs (journalctl -u grafana-server | grep -i provisioning) for parse errors.

Provisioning data sources

1. Write provisioning/datasources/datasources.yaml (see § Data source provisioning below)
2. Restart Grafana
3. Health-check the data source via API:

   curl https://grafana.example.com/api/datasources/uid/<uid>/health \
     -H "Authorization: Bearer <token>"
   # { "status": "OK", "message": "..." } → working
   # { "status": "ERROR", ... } → URL unreachable or auth misconfigured
   

Creating a service account + token

1. Provision via YAML or POST /api/serviceaccounts (full API in references/api.md § Users + service accounts)
2. Mint a token via POST /api/serviceaccounts/{id}/tokens
3. Verify the token works:

   curl https://grafana.example.com/api/org \
     -H "Authorization: Bearer <new-token>"
   # 200 + org JSON → token + role assignment work
   # 401 → token wrong; 403 → role wrong
   

Dashboard provisioning

# provisioning/dashboards/default.yaml
apiVersion: 1
providers:
  - name: default
    folder: MyFolder
    type: file
    disableDeletion: false
    updateIntervalSeconds: 30
    options:
      path: /var/lib/grafana/dashboards
      foldersFromFilesStructure: true

For the dashboard JSON shape itself (panels, queries, template variables), see references/dashboard-json.md.

Data source provisioning

# provisioning/datasources/datasources.yaml
apiVersion: 1
datasources:
  - name: Prometheus
    type: prometheus
    access: proxy
    url: http://prometheus:9090
    isDefault: true
    jsonData:
      timeInterval: 15s
      httpMethod: POST

  - name: Loki
    type: loki
    access: proxy
    url: http://loki:3100

  - name: Tempo
    type: tempo
    access: proxy
    url: http://tempo:3200
    jsonData:
      tracesToLogsV2:
        datasourceUid: loki_uid
        tags: [{ key: "service.name", value: "app" }]
      serviceMap:
        datasourceUid: prometheus_uid
      nodeGraph:
        enabled: true

  - name: Pyroscope
    type: grafana-pyroscope-datasource
    url: http://pyroscope:4040

RBAC (built-in roles)

Role	Permissions
Viewer	Read dashboards, alerts
Editor	Create/edit dashboards, alerts
Admin	Manage data sources, users, plugins
GrafanaAdmin	Server-wide admin (superuser)

Service-account provisioning:

# provisioning/access-control/service_accounts.yaml
apiVersion: 1
serviceAccounts:
  - name: ci-reader
    orgId: 1
    role: Viewer
    tokens:
      - name: ci-token
        # expires: optional ISO 8601 timestamp; omit for no-expiry tokens

(Custom RBAC roles with fine-grained permissions are Enterprise / Cloud only — see the grafana-cloud/admin skill if you need those.)

Plugin provisioning

# provisioning/plugins/plugins.yaml
apiVersion: 1
apps:
  - type: grafana-pyroscope-app
    disabled: false
    jsonData:
      backendUrl: http://pyroscope:4040

After restart, verify via GET /api/plugins/<plugin-id>/health.
