A Java framework that intercepts and logs database JDBC transactions without requiring code changes.
P6Spy is a Java framework that intercepts and logs all JDBC database transactions without requiring any code changes to the application. It provides developers with complete visibility into database interactions, including SQL statements, parameters, and execution times. This helps with debugging, performance optimization, and security auditing of database operations.
Java developers and database administrators who need to monitor, debug, or audit database interactions in Java applications without modifying existing code.
Developers choose P6Spy because it provides comprehensive database monitoring with zero code changes, making it easy to integrate into existing applications. Its transparent interception of JDBC transactions offers valuable insights for debugging and performance tuning without invasive instrumentation.
P6Spy is a framework that enables database data to be seamlessly intercepted and logged with no code changes to the application.

Works by simply configuring a JDBC driver, eliminating the need for code changes or instrumentation, as highlighted in the key features and README.
Captures all JDBC statements, parameters, and execution times, providing complete transaction visibility for debugging and auditing, as stated in the documentation.
Supports customizable logging to files or standard output, allowing easy integration into various development and production workflows.
Tracks query execution times for performance analysis and enables monitoring of database access patterns for security compliance, per the feature list.
Intercepting and logging every JDBC transaction introduces latency, which can be significant in high-throughput scenarios, as indicated by the dedicated performance testing repository (p6spy-perf).
Requires replacing the JDBC driver and tuning properties in spy.properties, which can be error-prone and environment-specific, as noted in the configuration documentation.
Only monitors interactions through JDBC, so applications using alternative data access methods or ORM optimizations may not be fully captured, limiting its scope.
