Abstract:
A method, system, and computer program product are provided for identifying instructions to obtain representative traces. A phase instruction budget is calculated for each phase in a set of phases. The phase instruction budget is based on a weight associated with each phase and a global instruction budget. A starting index and an ending index are identified for instructions within a set of intervals in each phase in order to meet the phase instruction budget for that phase, thereby forming a set of interval indices. A determination is made as to whether the instructions within the set of interval indices meet the global instruction budget. Responsive to the global instruction budget being met, the set of interval indices are output as collection points for the representative traces.
