Overview
Sometimes it may be observed that while there are many Users whose traffic is falling under the Recreational Group, on the Dashboard, however, there is a relatively small number of Hosts being shown in the Recreational widget. These two numbers should be equivalent.
Resolution
There is no permanent fix available at this time.
Workaround
Navigate to Monitor > Hosts to check the Top Users/Hosts. This provides an exhaustive list of the Hosts in the system.
