Conditions requiring administrative response are detected by observing values and/or patterns in the monitoring data
- triggers specify these patterns and invoke appropriate adaptation algorithms
- input to a trigger is a view of the monitoring data
- views and triggers can be specified separately to allow
- easy selection of desired reaction algorithm
- easy redefinition of conditions that invoke a particular reaction
Running example
- trigger: change in temperature of one shelf > 0 and more than twice the change in temperature of any other shelf, averaged over a one-minute period
