摘要： A user may specify a vector of metrics to be used while profiling a program. The vector of metrics may optionally be thread-relative. In response to a notification of an occurrence of the current event, a thread-relative elapsed metric is computed by: determining a current thread; retrieving a stored reference metric for the preceding event of the current thread; obtaining a current reference metric; and computing the thread-relative elapsed metric as a difference between the current reference metric and the stored reference metric. In order to prevent the generation of redundant metric information, the information associated with the vector of metrics maybe placed into the trace records in several different space-saving formats.

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 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.

摘要： A method and system for monitoring performance of a program using global metric variables to provide the support in an symmetric multiprocessor (SMP) system. A Java virtual machine (Jvm) either calls the profiler whenever bytes are allocated or provides an interface to allow the profiler to determine the value of the change in the metric for the current thread. The profiler then applies the changes to a metric for the current thread. Alternatively, per processor data areas are maintained for storing per processor metric values. Whenever a thread switch occurs or there is a request for the metric on a specified thread, an operating system kernel updates the thread level metric values with changes in the values per processor metrics.

摘要： A system and method for monitoring software locks is presented. Metric data collection is invoked only when thin lock contention arises in a computer system's application layer. Instrumentation in a computer system's middleware layer tracks time-based metric information such as a waiting time for an application to acquire a lock. Instrumentation tracks garbage collection events and removes garbage collection time durations from time-based metric data as to not distort time-based metric data. Instrumentation also tracks quantity-based events such as the number of applications that request a particular lock. An instrumentation user may retrieve metric data for computer system performance analysis.

摘要： A low-overhead performance measurement of an application executing in a data processing system is provided in order to generate per-thread performance information in a multithreaded environment. While a first set of events is being monitored for a particular thread as a first metric, events that may indirectly cause inaccuracies in the first metric, such as thread switches, are also monitored as a second metric. The presence of a positive value for the second metric is then used to determine that the first metric is inaccurate or unreliable, after which the first metric may be discarded; otherwise, the first metric is considered accurate. For example, the first metric may then be considered a thread-relative metric as it has been observed during a time period in which no thread switch events or interrupt events would have caused the first metric to become inaccurate during the execution of a particular thread.

摘要： During the recording of events occurring within the operation of a data processing system, a user-selected metric of interest is recorded along with the trace data for each recorded event. The metric of interest is a monotonically increasing variable that provides a non-time relationship between the recorded events. This relationship may be time or non-time based.

摘要： The present invention is a system, method, and computer readable medium for representing program event trace information in a way which is very compact and efficient, and yet supports a wide variety of queries regarding system performance. The tracing and reduction of the present invention may be dynamic, in which case information is obtained and added to the trace representation in real-time. Alternately, the tracing and reduction may be static, in which case a trace text file or binary file is obtained from a trace buffer, and the reduction takes place using the trace file as input. The trace information, whether obtained statically or dynamically, is represented as a tree of events. The present invention may be used to present many types of trace information in a compact manner which supports performance queries. For example, the tree structure of the present invention may reflect the call stacks observed during a program's execution, and statistics regarding the memory allocated/deallocated in the various routines and call stacks may be stored at each node of the tree. The tree structure may be used to store performance information regarding Java bytecodes executed, memory allocated, or other types of performance information. The trace information is presented in a manner which is compact and efficient, and may be used to quickly and easily answer a variety of performance queries. Further, a system may be traced for long periods of time without losing useful performance information due to a limited buffer space.
