PoWA
PoWA is a free, self-hosted tool for monitoring and tuning PostgreSQL. It collects and aggregates performance metrics from database instances and presents them in charts. Local mode handles one instance; remote mode gathers metrics from multiple instances into a repository server and can include read-only standbys without restarting PostgreSQL when adding them. The project combines the powa-archivist extension and powa-web interface, with an optional powa-collector daemon for remote deployments. Supported statistics extensions include pg_stat_statements, pg_qualstats, pg_stat_kcache, pg_wait_sampling, and pg_track_settings; pg_stat_statements is mandatory, and the current version targets PostgreSQL 9.4 and newer. HypoPG support enables testing hypothetical indexes without creating real ones. PoWA 5 adds datasource views for replication, background writer, checkpointer, SLRU, WAL, and PostgreSQL 16 or newer I/O statistics, plus per-database snapshots. Metrics can be enabled or disabled, and custom extensions added without modifying PoWA.
