Abstract:
1. A method for monitoring performance of an information technology system, the method comprising: retrieving, by a microprocessor of a computing device, data for a metric, said metric indicative of one or more operating parameters of the information technology system; identifying, by the microprocessor, a set of baseline patterns of the metric, each of the set of baseline patterns having a baseline; determining, by the microprocessor, whether the data matches one of the set of baseline patterns; if the data matches a first baseline pattern, selecting, by the microprocessor, a first baseline of the first baseline pattern as a possible dynamic threshold for the metric; or selecting a composite baseline if there is no matching pattern; evaluating the first baseline by conducting at least one sanity check on the first baseline to ensure that using the first baseline for the metric will result in accurate detection of abnormalities for the metric; if the first baseline passes the at least one sanity check, applying the first baseline as a new event threshold of the metric, to dynamically adjust an event threshold for the metric.
