Realtime data is reported for features on a license server group only if each aggregated feature has realtime data. This could lead to problems in grids that display realtime data (such as Most Utilized FeaturesRealtime Utilization), because realtime data would not be reported if a feature on one of the license servers in the group is no longer being used but has historical data. To avoid such problems, any feature on a license server group that had realtime data that was previously aggregated is no longer included in the aggregation if its usage is older than 24 hours.
