Abstract: A Nyquist sampling frequency is determined for performance counter events to be measured. Based on the Nyquist sampling frequencies, a schedule for measuring the performance counter events is determined. The performance counter event measurements are then conducted in accordance with the schedule, whereby the measurements yield a set of sample data for each performance counter event. A signal reconstruction algorithm is applied to the set of sample data for each performance counter event to reconstruct an essentially complete signal for each performance counter event. The essentially complete signal for each performance counter event is then used to improve either a design or a utilization of either a microprocessor or an application to be executed on the microprocessor.

Abstract: The present invention provides a method and apparatus for analyzing system error messages. The method includes accessing a report generated in response to an error. The method further includes accessing at least one predetermined error group and determining a probability that the error is associated with the predetermined error group.

Abstract: The present invention provides a method and apparatus for capturing system error messages. The method includes accessing information associated with an error. The method further includes identifying a category associated with the error based upon the accessed information and accessing at least one pre-determined attribute in the accessed information based upon the identified category.

Abstract: The present invention provides a method and apparatus for identifying occurrences of selected events in a system. The method includes determining if a first pattern is stored in a log file, determining if a second pattern is stored in the log file and indicating an occurrence of the event in the processor-based system in response to determining that the first pattern and the second pattern are stored in the log file within a preselected time of each other.
