Empty pages

The Query Performance page is empty

Query performance is reached from Queries under a database. The rest of DBGorilla looks healthy: the collector still connects and reports host metrics, database size, table statistics and topology.

Cause

pg_stat_statements is not loaded. This PostgreSQL extension records how long each statement takes, and every query-level feature reads from it.

Fix

Load pg_stat_statements. Loading it needs a full server restart, not a reload.

pg_stat_statements has the steps, including the ALTER SYSTEM SET caution that can require another restart.
