End-User Monitoring

End-User Monitoring (EUM) provides performance information from the point of view of the client, whether that client is a web browser or a mobile native application. This is different from other types of AppDynamics monitoring, which typically begin at the application server. You can monitor web use (by real users or synthetic agents), mobile use, or any combination, depending on your needs.

EUM helps you determine the extent to which poor user experience may be caused by problems in the browser or local app, or in the network, by showing you a breakdown of how much of the total end-user time is spent requesting service and then rendering the response data. In addition, for mobile apps it provides crash snapshots that include stack traces of the application at the time of the crash. EUM gives you visibility into client usage on a global basis, showing you, for example:

• where your heaviest loads originate
• where your slowest end-user response times occur
• how performance varies 
  • by location
  • by client type, device, browser and browser version, and network connection, for Web requests
  • by application and application version, operating system version, device, and carrier, for mobile requests
• what your slowest Web requests/Ajax requests are, and where the problem may lie
• what your slowest mobile network requests are, and where the problem may lie
• how application server performance impacts the performance of your web and mobile traffic

EUM produces its own data set that is separate from the data reported by app agents. This  data is visible in various EUM screens, via the Metric Browser, and, with the appropriate license, via AppDynamics Analytics. In addition, EUM data can be linked to the corresponding server-side business transaction information collected by app agents to give you a complete view of your end users' experience from the client request, through the backend, and on to the client response. 

 End-User Monitoring was previously named End User Experience Management (EUEM). 

Accessing End-User Monitoring

1. Select the User Experience tab.
2. Choose either Browser Apps (which includes RUM and Synthetic) or Mobile Apps.
3. Double-click the app in which you are interested to open the application UI.

By default, End-User Monitoring uses a cloud-based component, the EUM Cloud, to process EUM data, but this functionality is also available in an on-premises version. For information on using this version:

Install the EUM Server

Some functionality for EUM depends on the AppDynamics Platform Events Service.  In a SaaS environment, this is managed by AppDynamics, but it is also possible to use this functionality in an on-premises form.  To host the Events Service on-premises:

 Install the Controller

 Install the Events Service

 Since EUM produces additional metrics, you may need to re-evaluate your current configuration's ability to handle the additional load. See Additional Sizing Considerations.
