Description Heiko W. Rupp 2010-12-15 13:43:05 UTC 
org.rhq.enterprise.server.measurement.MeasurementDataManagerBean#findDataForResource()
offers (also on the remote interface to the CLI ) to specify a number of datapoints.
But doing so only works correctly when #datapoints = 60

This comes from calling into
org.rhq.enterprise.server.measurement.util.MeasurementDataManagerUtility#getMeasurementDataAggregatesForContext
then 
org.rhq.enterprise.server.measurement.util.MeasurementDataManagerUtility#getFullQuery

where the SQL is constructed

        + "   ) data GROUP BY timestamp) \n"
            + "   UNION ALL (select ? + (? * i) as timestamp, null as av, null as peak, null as low from RHQ_numbers where i < ?) ) alldata \n"


but RHQ_numbers only has 60 rows
