Grafana Management Log

Grafana provides dashboards and observability for blumeops.

Service Details

Embedding Note

Grafana panel embedding via iframes was attempted for Homepage but didn't work well:

  • Homepage's iframe widget doesn't support width constraints (only height)
  • Grafana's "Public Dashboards" feature doesn't support template variables or PostgreSQL datasources
  • Anonymous auth would be required, which exposes all dashboards

Current config has allow_embedding: false. If revisiting this, see git history for the iframe attempt (2026-01-30).

Datasources

Name Type URL
Prometheus prometheus http://prometheus.monitoring.svc.cluster.local:9090
Loki loki http://loki.monitoring.svc.cluster.local:3100
TeslaMate postgres blumeops-pg-rw.databases.svc.cluster.local:5432

Dashboard Provisioning

Dashboards are provisioned via ConfigMaps with label grafana_dashboard: "1". The sidecar watches for these and loads them automatically.

To add a dashboard:

  1. Create ConfigMap in argocd/manifests/grafana-config/dashboards/
  2. Add label grafana_dashboard: "1"
  3. Optionally add annotation grafana_folder: "FolderName" for organization
  4. Sync the grafana-config ArgoCD app
