CALL PATH REFINEMENT PROFILES

A method and system for measuring the usage of a focus resource by a target program which has a plurality of call paths and at least one procedure, which allows a user to select a focus call path from a call path profile and compute a refinement call path profile which shows the usage of the focus resource by refinement call paths of the focus call path. Methods and systems are disclosed for deriving the call path profile, pruning and unpruning the call path profile, defining function groups, optimizing and contextualizing. Computation of the refinement call path profile can be performed by immediate upward or downward and extended upward or downward refinement of the call path profile.
