  • Generating problem signatures from snapshots of time series data
    Patent number: 9632859
    Abstract: Software that generates statistical models of events impacting computer systems and uses those models to detect similar events in the future. The software performs the following operations: (i) receiving a snapshot of a first event impacting a computer system, where the snapshot includes a first set of values for a plurality of metrics occurring over a first time period corresponding to the first event; (ii) extracting a first set of feature vectors from the first set of values; (iii) generating a first statistical model representing the first event based, at least in part, on the extracted first set of feature vectors; and (iv) determining that a second event is similar to the first event by comparing the first statistical model to a second set of values for the plurality of metrics occurring over a second time period corresponding to the second event.
