RED metrics dashboard, straight from your spans
The Metrics screen is live: request rate, error percentage and latency percentiles over time for the busiest services of the window — derived from the same spans the trace explorer uses, so there is nothing extra to instrument or operate.
- Per-service cards. Rate, errors and p50/p95/p99 duration charts over the selected window; filter to one service or let the backend pick the busiest.
- Same filters everywhere. Global time range, auxiliary-traffic toggle, URL-shareable state — and every card links back to the service's traces.
- API first.
GET /api/v1/metrics/redserves the bucketed series to any client, not just the UI.
