A system and method for constructing a user callstack trace in a computer to monitor a user defined Function of a user program in relation to one or more predetermined events is provided. The system and method provides generating a user callstack trace for display to the user from data in memory in relation to a predetermined event of interest to the user. The user callstack trace communicates information corresponding to the execution of the Function for the predetermined event independent of the plurality of outlined functions. The plurality of outlined functions are artificially generated in response to compiling the user program having the Function.

A data space profiler may include an analysis engine that associates runtime events of profiled software applications with execution costs and extended address elements. Relational agents in the analysis engine may apply functions to profile data collected for each event to determine the extended address element values to be associated with the event. Each extended address element may correspond to a data profiling object (e.g., hardware component, software construct, data allocation construct, abstract view) involved in each event. The extended address element values may be used to index into an event set for the profiled software application to present costs from the perspective of these profiling objects. A filtering mechanism may also be used to extract profile data from the event set corresponding to events that satisfy the filter criteria. By alternating between presentation of profiling object views and filtered event data, performance bottlenecks and their causes may be identified.
