      org.rhq.domain.correlation.MetricNormalizationRule

public class MetricNormalizationRule
extends NormalizationRule

Normalization rule for metrics (Numeric, traits). The rule does not store the conditions in itsels, but uses a list of MetricNormRuleItems for this. MetricNormalizationRules are keyed by the ID of the MeasurementSchedule they operate on.
