Abstract
Events in a first data stream are correlated with events in a second data stream based on a method of indexing. As information of a first and second data stream are stored to a data file, the data streams are monitored for certain trigger events. An informational data set is generated and stored in an index file for each detected trigger event. Preferably, each informational data set includes the type of detected event, a time-stamp indicating when the event occurred and a data pointer indicating where the data associated with the event is stored in a corresponding data file. When time-stamps of detected trigger events in both data streams are generated based on a common system clock, data in one data stream is correlated with data in another data stream based on the time-stamps.
