SolarWinds Database Performance Analyzer (DPA) provides comprehensive database monitoring and performance analysis across multiple database platforms. The tool uses wait-time analysis methodology to identify performance bottlenecks—focusing on what queries are waiting for rather than just execution time. Supports Oracle, SQL Server, MySQL, PostgreSQL, MariaDB, Aurora, and Azure SQL. Pricing is per-instance monitored, typically starting around $1,500-2,000 per instance annually. Key features include 24/7 monitoring with anomaly detection, response time analysis drill-down, advisor recommendations for indexing and query changes, and cross-platform correlation for applications spanning multiple databases. The anomaly detection uses machine learning to identify unusual patterns without manual threshold configuration. Historical data retention enables trend analysis and capacity planning.
