Trend, Spike, and Exceeded Standard Deviation components
Trend components detect changes in activity measured over defined periods of time. Before you can create a trend component, your trigger system must include a Container or Select component that the trend can use as a data source.
The Spike component
The Spike component looks for a significant jump or a significant drop in comparison to a historical value. Spike components are used as filters for Action components, Container Manipulators, and Boolean expressions.

The Spike component

The Spike component looks for a significant jump or a significant drop in comparison to a historical value. Spike components are used as filters for Action components, Container Manipulators, and Boolean expressions.

Based on the parameters you set, the system formulates two values then compares the two values. The Spike component returns true if the Spike Period Value is greater than or less than the Historic Value For Period by the specified percentage.
