What is Mobile EUEM?
Mobile End User Experience Management (Mobile EUEM) allows you to understand your native iOS or Android mobile application as your end-users actually use it. It provides you with visibility into the functioning of the application itself and the application's interactions with the network it uses and any server-side applications it may talk to. You can:
- Understand and improve your mobile application's performance
- Determine whether a request is slow because of your servers or because of the network connection. See .
- Trace an individual request from the initial user action in the mobile application through the associated business transaction(s) on the application server(s). See Network Request Snapshots.
- Estimate the network performance you can expect for different requests, carriers, devices, and geographies by viewing current metrics. See Monitor Usage Statistics.
- Compare your application's performance across application versions. See Monitor Network Requests by Mobile Application Version.
- Reduce crashes
- Reduce errors
- Learn about your users
- Customize the data that Mobile EUEM returns
How Does Mobile EUEM Work?
To use mobile EUEM you add a small piece of highly performant code, the mobile agent, to the source of your application. This process is called instrumenting and is described here. As your end-users interact with your application, the agent collects metrics and any error information on the application's performance and sends that information to the AppDynamics controller UI, where it is displayed in a series of dashboards and charts. If your application crashes, the agent also creates a crash snapshot with information to help you analyze what happened, including the crashed function, the source file containing the crashed function, the line number, if available, and a stack trace of the application at the time of the crash, along with various other identifying data. And if the server-side application with which your mobile app interacts is also instrumented, you can get correlated metric information for the entire round-trip request life-cycle.
Data collected by the agent is sent to the Cloud for processing when the agent detects that the application it is monitoring is already using the network, minimizing the time that the device's radio is in a high power state. The data is sent in a beacon, a bundled set that is around 200-400 bytes. If for any reason the Cloud is not available, the agent buffers data locally.
If the Cloud is unavailable for extended periods of time, the agent may delete older data to prevent unbounded growth in the buffer.
Licensing and Enabling Mobile EUEM
Mobile EUEM requires a separate license from that for your application server and for Web End User Experience Monitoring, and must be enabled before it is available for use. Until it is enabled it does not appear in the left navigation bar of the AppDynamics GUI.
For information about licensing, including a description of the two types of licenses, Lite and Pro, see Mobile EUEM Licenses.
For information on enabling or disabling Mobile EUEM monitoring, see Enable Mobile EUEM on Your Controller.
