Enabling aggregated statistics across cluster members
Under Aggregated Statistics Settings, select the check box and click Apply.
Time-series data aggregated across the entire cluster are applied to the Desktop Traffic, Desktop Bandwidth, SSL, Branch Warming, and Endpoint History reports. A message appears at the bottom of the report stating whether the data was successfully retrieved from all cluster members. For more information on endpoint reports, see Viewing reports for endpoints.
