# Watch size and growth

By Erik Bergstedt, Agent Wranglers. Updated 2026-10-20.

- Level: Recommended
- Chapter: [Operations](https://agentwranglers.se/playbook/data/operations)
- Rule: Track how fast the database and its biggest tables grow, and alert well before disk or plan limits are reached.
- How: Record the database and table sizes daily. Alert at 70% of disk or plan capacity, which leaves time to act. Large tables of old rows are candidates for retention jobs or partitions by date. This rule measures stored size, not traffic. Traffic headroom is a separate rule in the operations playbook.
- Check: The monitoring shows a size graph for the database, and a test alert fires when the threshold is lowered below today's size.
