The storage analysis feature in PolarDB for PostgreSQL quick diagnostics — powered by Database Autonomy Service (DAS) — gives you a consolidated view of your cluster's storage health. Use it to track overall storage consumption, estimate how many days of capacity remain, and pinpoint storage anomalies at the database and table level.
Limits
Storage analysis supports up to 20,000 tables.

Click the Storage Analysis tab.
On the Storage Analysis page, choose a tab based on what you want to view:
