There are three types of Flow Monitor workspace reports.
These types vary depending from where in the application you modify your report and workspace views.
If you add workspace reports to the Interface Details report in Flow Monitor, you see Interface Details and Troubleshooting categories on the Configure Flow Interface Report dialog.
If you add workspace reports to a workspace view in WhatsUp Gold, you see Interface Details, Interface Troubleshooting, and Interface Traffic on the Add Content To View dialog.
