MetricA metric is the result of a calculation based on one or more values in the KDRs. Various functions define how these values should be aggregated in each period.
Service ModelA service model is set of objects that defines dimensions, metrics, trees, and KPIs and the relation between these entities.

Period

Metrics are aggregated in discrete periods. The length of these periods is determined by properties in the service models.
