Grafana connects to RisingWave as a PostgreSQL data source — no plugins needed. Materialized views update in real time, so your Grafana dashboards show live streaming data without manual refresh.
Setup Steps
1. Add PostgreSQL Data Source in Grafana
- Go to Configuration → Data Sources → Add → PostgreSQL
- Host:
risingwave-host:4566 - Database:
dev - User:
root - SSL Mode: disable (or configure TLS)
2. Create a Dashboard Panel
-- Example query for Grafana panel
SELECT window_start as time, event_type, count as value
FROM events_per_minute
ORDER BY window_start DESC
LIMIT 100;
3. Set Auto-Refresh
Set dashboard auto-refresh to 5-10 seconds. RisingWave materialized views are always current, so every refresh shows the latest data.
Tips
- Use
$__timeFilter(time_column)for Grafana time range integration - Materialized views are pre-computed — queries are fast (10-20ms)
- No need for separate cache or API layer
Frequently Asked Questions
Does Grafana support RisingWave natively?
Grafana connects to RisingWave via the built-in PostgreSQL data source. No special plugin needed. Any query that works in psql works in Grafana.
