What's Changed

Added

  • Grafana: Streamlined dashboard layout — Dashboard rebuilt to 4 sections and 9 panels: GreenKube Impact Command Center (radar, footprint mix, impact ledger, action priorities), CO₂e by Namespace (pie charts, now promoted to second position above the map), Regional Node Cleanliness (geomap), and Top Emitters & Spenders (top-15 pods by CO₂e and cost). Eight rows and their associated panels removed.
  • Recommendations: Annualised savings — Each recommendation now exposes projected annual CO₂e savings (annual_co2e_savings_grams) and annual cost savings (annual_cost_savings_usd), extrapolated from the observation window. Values are surfaced in the API response, the frontend recommendations page, and CLI output.
  • Report: Yearly and custom date ranges — GET /api/v1/report now accepts a 1y (calendar year-to-date) window and arbitrary start/end timestamps. Reports can additionally be grouped by namespace via the group_by_namespace query parameter.
  • Recommendations: Savings ledger integration (#237) — Applied recommendations now trigger a savings-ledger entry. A new flow updates RecommendationRealization records and kicks off a background refresh of the savings attribution so the greenkube_co2e_savings_attributed_grams_total and greenkube_cost_savings_attributed_dollars_total gauges stay consistent as metrics accumulate.
  • Recommendations: GET /api/v1/recommendations/top — New API endpoint returning the highest-impact active recommendations ranked by projected annual savings. Returns TopRecommendation DTOs with rank, projected annual CO₂e savings, and projected annual cost savings.
  • Prometheus: greenkube_top_recommendations gauge — New Prometheus gauge exposing ranked active recommendations.
  • Grafana: Actionable Recommendations section — New dashboard row showing the top-N ranked recommendations as horizontal bar cards with projected annual CO₂e and cost savings.
  • App startup recommendation scan: The API now triggers a full scan for recommendations on startup, ensuring the dashboard and API have immediate data to work with even if no new metrics have come in since the last scan.

Changed

  • Grafana: $node and $region template variables removed — Both variables have been dropped from the dashboard.
  • Grafana: Dashboard generator cleaned up — Unused panel helpers removed from scripts/build_grafana_dashboard.py, together with the constants no longer referenced by any remaining panel.

Fixed

  • Recommendations: CPU and memory rightsizing - Stop displaying rightsizing recommendations that suggest increasing requests.
  • Security: Frontend dependency updates — package.json / package-lock.json updated to remediate Trivy-flagged vulnerabilities in transitive frontend dependencies.
