Abstract
A method and apparatus for merging data acquired by two or more capture devices from two or more points in a computer system, duplicate frames are analyzed to determine the time difference between the timestamp of a first capture device and the timestamp of a second capture device. The invention compares the frames for duplicates. If the duplicate frames are the first set of duplicate frames discovered, then all previous timestamps and all subsequent timestamps from the second capture device are adjusted by the calculated time difference. If duplicate frames are again discovered, the time difference is recalculated and all subsequent frames from the second capture device are adjusted by the calculated time difference. After all the frames have been analyzed and the timestamps adjusted, the frames are merged together and put into chronological order to simulate a single capture of data encompassing all of the points where the data was collected.
