public class ThresholdMonitor
extends org.lsst.ccs.framework.Module

Monitors a value and set alarms if goes below/above thresholds An alarm message is sent when variable goes above highLimit or below lowLimit. An alarm cleared message is sent when variable goes back between lowLimitClear and highLimitClear
