Abstract

A method and apparatus in a data processing system. The apparatus includes a performance event record generation component for generating a performance event record according to the system clock for a performance event monitored in the data processing system and a performance event record storage component for storing the performance event record generated by the performance event record generation component. The method in a data processing system according to the present invention includes the steps of: generating a performance event record based on the system clock for a performance event monitored in the data processing system; storing the generated performance event record; and arbitrating the storage conflict when multiple performance event records are generated at the same time in the step of generating a performance event record, in order to determine the storage order of the performance event records.
