Enterprise view
Enterprise view is the starting point where you add, remove and arrange the items you would like to monitor, view some basic information about them, enable and disable items, view and configure alerts.
Instance view
Oracle Instance view is a detailed real-time snapshot of an Oracle database showing performance and other critical
information for a single Oracle instance. The layout of the Instance view reflects the way Oracle works at the conceptual
level - from users and sessions at the top over the network down to memory components (SGA and PGA)
and eventually saving the data and reading it from storage
Drilldowns
In addition to its real-time capabilities Insider features a rich set of drilldown views to cover all areas of performance diagnostics. From memory and storage to the current user activity and load you can analyze over a hundred different views to get a complete picture of your system health.
