One of the best tools we have today for understanding application behavior and troubleshooting performance issues are Java profilers. Java profilers monitor JVM execution at the bytecode level and can provide information on thread execution and locks, heap memory usage, garbage collection, hot methods, exceptions, class loading, and more.
