getSummaryAggregateAsync

public com.google.common.util.concurrent.ListenableFuture<AggregateNumericMetric> getSummaryAggregateAsync(int scheduleId,
                                                                                                  long beginTime,

addNumericData

public void addNumericData(Set<org.rhq.core.domain.measurement.MeasurementDataNumeric> dataSet,
                  RawDataInsertedCallback callback)

calculateAggregates

public Iterable<AggregateNumericMetric> calculateAggregates()

Computes and stores aggregates for all buckets that are ready to be aggregated. This includes raw, 1hr, 6hr, and 24hr data.

Returns:

One hour aggregates. That is, any raw data that has been rolled up into onr one hour aggregates. The one hour aggregates are returned because they are needed for subsequently computing baselines.
