All Loupe data that comes to your server is displayed in Loupe View. The default display at the top of Loupe View is a list of all of the sessions that have been sent to your repository.
The Sessions view is the top (default) option in the main navigation under the View module. Selecting it will display the list of the latest sessions received into your repository. You can filter this list to find a particular session.
When you've found a session you're interested in seeing more details on, clicking on it will show a summary view of the session along with tabs for an related events, alerts, the log, and key metrics.
Loupe also tracks the unique application users found in your log data and has an Application Users view accessible from the main navigation under the View module.
For more information on how Loupe helps you support individual users, see User's Guide - View - Application Users
Each application you want to view in Loupe will need to have a Loupe Agent added to it. Follow the instructions for your scenario in Getting Started - Introduction to add Agents and start collecting data.
