Class CapacityPlanningData

java.lang.Object

org.epics.archiverappliance.mgmt.archivepv.CapacityPlanningData

public class CapacityPlanningData
extends Object

Data from various appliances that is used for capacity planning. We assume that policies have been applied for this PV and that typeinfo is available. We gather data from various appliances (engine + ETL + storage) as it applies to this PV. Capacity planning consists of measured data and estimated data. The estimated data is available from the configService as ApplianceAggregateInfo The measured data is available thru this class. As the measured data does not change very often, we cache this locally for a time period as defined by MEASURED_DATA_CACHE_TIME
