    In most cases, a user's interaction with your app is not limited to one action in one screen view. Sessions allow you to track your users' interactions across time, as they navigate an entire session with your app.

    By default, sessions begin when a user starts using your application and ends after a configurable period of user inactivity. You can also, however, programmatically control sessions through the Mobile Agents SDKs (AndroidiOSXamarinCordova). Using Mobile Sessions you can analyze sessionized results from all requests, as stored in the AppDynamics Events Service. 

    As in Network Request Analyze, the main Sessions screen is made up of two tabs:

    You can also view detailed information about each session in the Session Details dialog.


    The Records tab lets you scan individual sessions and allows you to filter and sort to get exactly the data in which you are interested.

    Session Details

    Click View Details or double-click an item to see the information for a specific session.

    Session Timeline

    The sequence of session frames for the session is shown on the session timeline and on the bottom of the screen. Select a specific frame by clicking on an icon on the timeline to see details highlighted at the bottom of the screen. You can also select a frame row at the bottom to see it highlighted on the timeline.

    Session Details Categories and Types
    The current Activity in the foreground of an Android app. If the current Activity is not sufficient to understand what the user is doing, consider using the Session Frame APIs.
    Root Views
    The current Root View in the foreground of the iOS App. If the current Root View is not sufficient to understand what the user is doing, consider using the Session Frame APIs.
    Session Frames
    Session Frame
    A manual API to label large user activities that are not captured out of the box by Activity or RootView tracking.
    If you have configured mobile screenshots, they will appear in the timeline. They capture user events, and they can also be collected when in automatic mode.

    User Interactions


    If you have enabled the Mobile Agent to capture UI events, you can view the UI events triggered by user interactions in the Timeline. See "Enable User Interaction Capture Mode" (iOS/Android) to learn how to capture UI events.


    If automatic screenshots are enabled, touches will be captured and include the screenshot that was captured at the same time. The touches are drawn on the screenshot.
