org.epics.archiverappliance.config.ApplianceAggregateInfo

public class ApplianceAggregateInfo
extends Object

POJO facilitating various optimizations for BPL that uses appliance wide information. The correct values for most of this is obtained by iterating thru the PVTypeInfo's and aggregating them. To improve performance for business logic that takes the entire appliance into consideration, a few aggregated parameters are stored and maintained here. There are no transactional guarantees with the information aggregated here; if the perfect/best information is desired, walk thru the PVTypeInfos. This is available within the appliance for that appliance.

Method Detail

clone

public ApplianceAggregateInfo clone()

Overrides:

clone in class Object

addInfoForPV

public void addInfoForPV(String pvName,
                         PVTypeInfo typeInfo,
                         ConfigService configService)

getTotalStorageRate

public double getTotalStorageRate()

Gets the aggregated total computedStorageRate for this appliance

Returns:

totalStorageRate  

getTotalEventRate

public double getTotalEventRate()

Gets the aggregated total computedEventRate for this appliance

Returns:

totalEventRate  

getTotalPVCount

public double getTotalPVCount()

Gets the aggregated pv count for this appliance.

Returns:

totalPVCount  

setTotalStorageRate

public void setTotalStorageRate(double totalStorageRate)

setTotalEventRate

public void setTotalEventRate(double totalEventRate)

setTotalPVCount

public void setTotalPVCount(double totalPVCount)

getTotalStorageImpact

public HashMap<String,Long> getTotalStorageImpact()

The storage impact is the impact of a PV on the particular store. It is the product of the estimated storage rate and the partition granularity of the source. This returns the aggregated impact on the various stores on this appliance indexed by the identity of the store.

Returns:

totalStorageImpact

setTotalStorageImpact

public void setTotalStorageImpact(HashMap<String,String> totalStorageImpact)

getDifference

public ApplianceAggregateInfo getDifference(ApplianceAggregateInfo other)

This returns a new ApplianceAggregateInfo that is the difference between this info and the other info. Used to maintain the delta of ApplianceAggregateInfo's between the periodic fetches of the CapacityPlanningMetricsPerApplianceForPV

Parameters:

other - ApplianceAggregateInfo

Returns:

ApplianceAggregateInfo
