Claim:
1. A method for identifying correlations between events recorded in a system log of a computer, the recorded events generated by a plurality of processes executing on the computer, the method comprising: partitioning, by the computer, a system log into a plurality of segments, each segment associated with a characteristic found in an event, each segment including one or more events having a same characteristic value; selecting, by the computer, a plurality of attributes of the one or more events in a segment, wherein the plurality of attributes do not describe an action of the event; generating, by the computer, one or more distinct n-grams, each distinct n-gram including the selected attributes from successive events within the segment, wherein a distinct n-gram is distinct from all other generated n-grams; identifying, by the computer, a correlation for each first selected attribute of each of the successive events of an n-gram with all other second selected attributes from each of the successive events of the n-gram; generating, by the computer, a correlation metric as a function of the number of correlated first selected attributes and the total number of selected attributes of each of the successive events of the n-gram, wherein generating the correlation metric includes: recording, by the computer, the correlations for each first selected attribute.
