The retention strategy that vRealize Hyperic uses for measurement data is it to store the minimum amount of data required to pinpoint when changes in performance or availability occur.

By default, detailed measurement data is stored for two days, after which the data is compressed and archived as hourly averages with highs and lows. You can configure vRealize Hyperic to keep detailed measurement data for up to a maximum of seven days.

To support requirements for trend analysis over a longer time frame, vRealize Hyperic provides the MetricDataReplicator class, which you can use to replicate uncompressed measurement data in a secondary database.
