Hamza Sajawal looks at a Redgate product:
pgNow is a lightweight PostgreSQL diagnostic tool developed by Redgate that provides quick visibility into database performance without requiring agents or complex setup. It connects directly to a PostgreSQL instance and delivers real-time insights into query workloads, active sessions, index usage, configuration health, and vacuum activity, helping DBAs quickly identify performance bottlenecks. Because it runs as a simple desktop application, pgNow is particularly useful for quick troubleshooting and point-in-time diagnostics when a full monitoring platform is not available.
The tool is currently free to use, and its development is actively maintained by Redgate, with potential future enhancements expected as the project evolves. It analyzes workload behavior using PostgreSQL system views and extensions such as pg_stat_activity and pg_stat_statements.
