Dynamically profiling consumption of CPU time in Java methods with respect to method line numbers while executing in a Java virtual machine

摘要

Various embodiments of a computer-implemented method, system and computer program product monitor the performance of a program component executing in a virtual machine. Breakpoints associated with position indicators within the program component are set. In response to reaching one of the breakpoints, an amount of time consumed between the breakpoint and a previous breakpoint is determined. The amount of time associated with the position indicators is accumulated. The amount of time is associated with a position indicator that is associated with the previous breakpoint.
