…ted_at index
- Add api_performance_dashboard.json with two rows:
- Project Activity: CPU allocation by project (Prometheus), most active
projects table and build submission rate (Postgres) — works immediately
with existing data sources
- API Request Metrics: endpoint request rate, top endpoints table and
latency p95 panels (Prometheus) — ready for when Flask middleware is
added, show "No data" until then
- Set dashboard auto-refresh to 5m to avoid excess DB load
- Add migration 00049 to create build_created_at_idx, eliminating full
table scans on time-range queries against the build table

Summary
api_performance_dashboard.json— new Grafana dashboard with two rows:00049to createbuild_created_at_idxonbuild(created_at), eliminating full sequential scans on time-range queriesContext
Part of DM01-6252 / DM01-6243 — InfraBox performance investigation.
The existing Prometheus metrics server only exposes job counts and resource allocation. This dashboard adds visibility into which projects drive the most load, using existing data sources immediately, with placeholder panels ready for the upcoming Flask request metrics middleware.
Risk
00049usesIF NOT EXISTS; safe to re-run. Migration runner kills all connections before applying migrations so noCONCURRENTLYis needed
