The Activity Dashboard for ArcGIS app generates various usage reports on content, members, and groups in Portal for ArcGIS. The number of views are registered in the usage details chart when an item is clicked in the Content tab.
Some items may have anonymous access enabled. When accessing portal items anonymously, the views are registered in the Activity Dashboard. However, the number of views of the item represents both anonymous and non-anonymous views, and the number of anonymous views are not exclusively recorded. The app does not provide the ability to generate chart based on levels, roles, and administrative access.
