Method Detail

purgeTraits

public int purgeTraits(long oldest)

Specified by:

purgeTraits in interface MeasurementDataManagerLocal

mergeMeasurementReport

public void mergeMeasurementReport(org.rhq.core.domain.measurement.MeasurementReport report)

Specified by:

mergeMeasurementReport in interface MeasurementDataManagerLocal

addNumericData

public void addNumericData(Set<org.rhq.core.domain.measurement.MeasurementDataNumeric> data)

Add metrics data to the database. Data that is passed can come from several Schedules, but needs to be of only one type of MeasurementGathering. For good performance it is important that the agent sends batches as big as possible (ok, perhaps not more than 100 items at a time).

Specified by:

addNumericData in interface MeasurementDataManagerLocal

Parameters:

data - the actual data points

addTraitData

public void addTraitData(Set<org.rhq.core.domain.measurement.MeasurementDataTrait> data)
