Updated October 11, 2026 The Monitoring tab shows how the database is doing: charts for the last hour to the last week, the queries that take the most time, the server log and the activity on the database. Raff also emails you when a database goes down or fills up.

​
Before you start

  • A running database. Numbers appear about a minute after it starts.

​
Charts

Open the database and go to Monitoring, Charts.
  • Pick the window: 1h, 6h, 24h or 7d.
  • Tiles: slow queries, peak connections (direct and pooled for PostgreSQL), disk usage, memory and CPU.
  • Traffic by client (PostgreSQL, MySQL): which users send the most work.
  • Replication lag (high availability) and Archive lag (PostgreSQL backups).
The Overview tab shows the same numbers live under Health.

​
Slow queries

Go to Monitoring, Queries (Slow commands on Valkey). The list shows the statements that took the most total time, with how often they ran and their mean time: start there to decide what to index or rewrite. On PostgreSQL, turn on pg_stat_statements first: Settings, Extensions. See Turn on extensions.

​
Logs

Go to Monitoring, Logs for the newest lines of the server log. Show system adds the engine’s own background messages.

​
Activity

Monitoring, Activity lists what happened to the database (created, resized, backed up, public access changed, password rotated) and who did it. Export CSV downloads it.

​
Alerts by email

Raff emails the project when: See Status and health.
