摘要： A method, apparatus, and computer instructions for providing pre and post handlers to log trace records before entering or after exiting the interrupt handler. A trace record includes a ‘from’ address where the interrupt occurs or where the branch instruction is executed or a ‘to’ address for the branch to case and counts of selected performance monitoring events. A timestamp may be associated with each event. In one embodiment, the pre and post handler is used with trap on branch to log trace records prior to and immediate after taking a branch. In another embodiment, a pre handler is enabled to log trace records that occur prior to executing interrupt service routines. A post handler is enabled to log trace records that occur after the interrupt service routines is executed and prior to returning to normal execution. Resulting low-level performance trace data may be collected by the user at a later time for more structured performance analysis.

摘要： A method, apparatus, and computer instructions in a data processing system for processing instructions are provided. Instructions are received at a processor in the system. If a selected indicator is associated with the instruction, counting of each event associated with the execution of the instruction is enabled. The performance indicators and counter values may be used as a mechanism for identifying cache hits and cache misses. Performance counters are incremented each time the instructions of routines of interest are executed and each time the instructions must be reloaded into the cache. From the values of these counters the cache hit-miss ratio may be determined. When the cache hit-miss ratio becomes less than a predetermined threshold, i.e. a greater number of cache misses than cache hits, the present invention may determine that a problem condition has occurred and initiate “chase tail” operations for avoiding overwriting of entries in the cache.

Instructions are received at a processor in the data processing system. If a selected indicator is associated with the instruction, counting of each event associated with the execution of the instruction is enabled. In some embodiments, the performance indicators, counters, thresholds, and other performance monitoring structures may be stored in a page table that is used to translate virtual addresses into physical storage addresses. A standard page table is augmented with additional fields for storing the performance monitoring structures. These structures may be set by the performance monitoring application and may be queried and modified as events occur that require access to physical storage.

摘要： 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 on 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.
