1. A dynamic thresholding system comprising, in combination: a computer in data communication with an information technology infrastructure, the computer having: a data collection module that collects metric data and stores the metric data on a storage device from at least one metric in the information technology infrastructure; and a dynamic threshold generator for creating a dynamic threshold based on a set of historical metric data, comprising: a model execution engine for analyzing the historical metric data based on at least one analytics model in an analytics model library; an analytics model library rule that defines parameters used by the model execution engine to form a transformed metric data set; and a trend detecting module for detecting a trend, the trend occurring when incoming metric data substantially exceeds the dynamic threshold for a predetermined number of time slices; wherein the dynamic threshold generated from the dynamic threshold generator is not static from one time slice to another time slice; and wherein a resolution module causes an alarm when a trend is detected.
