Abstract: PROBLEM TO BE SOLVED: To provide information to relate between a class file and an instrumentation. SOLUTION: In a support method of user-specific instrumentation, when loading a class, a hook specifying a major code and a minor code for each method, which is instrumented to a method name, is outputted to, for example, a trace record. Next, when making the method an entry or an exit, a hook specifying the entry or the exit is also outputted to the record. When the record is performed in a post-processing, since it becomes enabling to acquire the information to relate the class file to the instrumentation from the record in a trace stream, the information is used for a merge.

Abstract: An apparatus and method for cataloging symbolic data for use in performance analysis of computer programs is provided. The apparatus and method stores symbolic data for loaded modules during or shortly after a performance trace and utilizes the stored symbolic data when performing a performance analysis at a later time. A merged symbol file is generated for a computer program, or application, under trace. The merged symbol file contains information useful in performing symbolic resolution of address information in trace files for each instance of a module. During post processing of the trace information generated by a performance trace of a computer program, symbolic information stored in the merged symbol file is compared to the trace information stored in the trace file. The correct symbolic information in the merged symbol file for loaded modules is identified based a number of validating criteria. The correct symbolic information for the loaded modules may then be stored as an indexed database that is used to resolve address information into corresponding symbolic information when providing the trace information to a display for use by a user.

Abstract: Un método de identificación de datos simbólicos para módulos cargados asociado con un programa de ordenador bajo análisis de rendimiento, que comprende: leer los datos de rastreo para un módulo cargado, comprendiendo dicho rastreo al menos un atributo para identificar el módulo cargado; hacer corresponder al menos un atributo con el correspondiente atributo o atributos cargados identificando el módulo cargado comprendido de un archivo de símbolo, en el que el archivo de símbolo comprende datos simbólicos combinados a partir de una pluralidad de fuentes de datos simbólicos asociados con el programa de ordenador y en el que cada atributo tiene una prioridad asociada; y usar la prioridad para determinar los datos simbólicos en el archivo de símbolos que mejor coinciden con los datos de rastreo.
