Abstract
A technique for analyzing software in which un-instrumented components can be discovered and dynamically instrumented during a runtime of the software. Initially, an application configured with a baseline set of instrumented components such as methods. As the application runs, performance data is gathered from the instrumentation, and it may be learned that the performance of some methods is an issue. To analyze the problem, any methods which are callable from a method at issue are discovered by inspecting the byte code of loaded classes in a JAVA Virtual Machine (JVM). Byte code of the class is parsed to identify opcodes which invoke byte code to call other methods. An index to an entry in a constants pool table is identified based on an opcode. A decision can then be made to instrument and/or report the discovered methods.
