1. A method comprising:
- collecting data by a computer-implemented performance monitoring system corresponding to a metric of an information technology system;
setting a threshold value corresponding to the metric;
generating a baseline corresponding to the metric; and
generating a prediction that the metric will violate the threshold only if at least some of the data corresponding to the metric are outside of the baseline.

Abstract
A baseline technique allows reducing the number of threshold violation predictions that need to be generated in a performance monitoring system. One or more baselines may be calculated based on long-term trends in a monitored metric. If the metric is within the baseline, then predictions regarding short-term trends in the metric may be omitted. If the metric is outside the baseline, then short-term trends may be analyzed to predict possible threshold violations.

15. A method, comprising:
-
collecting data by a computer-implemented performance monitoring system corresponding to a metric of an information technology system during a first measurement period; setting a threshold value corresponding to the metric; generating a first baseline value for the first measurement period corresponding to a first condition; generating a second baseline value for the first measurement period corresponding to a second condition, wherein the first baseline value and the second baseline value define a baseline range for the first measurement period; calculating a trend of the data corresponding to the metric collected during a measurement period; and generating a prediction that the metric will violate the threshold only if a statistically significant number of data values collected during the first measurement period corresponding to the metric are outside of the baseline range and the trend is toward the threshold. - View Dependent Claims (16, 17)
