How it works
Statuses
Checks
- Engine: whether it is ready, every few seconds.
- Connection path: every minute, Raff connects through each database’s public address the way your apps do, without logging in.
- Storage and connections: every minute, faster when storage passes 50%.
Emails
Sent to the project’s members:- Down: after 2 minutes without answering, and back up when it answers again, with how long it was down.
- Storage: at 80% and 90% of the plan’s storage, at most once a day each; when PostgreSQL or MySQL become read-only at 95%, and when writes work again.
- Free databases: before a free database pauses for idleness, when it pauses, and reminders while it stays paused.
When to use it
- Watch the Monitoring tab for trends; rely on the emails for incidents.
- A Degraded or Down database shows the cause on its Overview tab.
Trade-offs
- A short restart during a resize is expected and does not count as down.
- Statuses refresh every few seconds in the dashboard; the API returns the same values.
