While application performance monitoring measures user interaction starting at the web server or application server entry point, EUM extends that visibility all the way to the web browser, mobile, or IoT application. As a result, it reveals the impact the network and browser rendering time have on the user experience of your application.
The diagram below provides an overview of the different components, deployment models (SaaS/on-premises), and the Controller UI as seen by AppDynamics end users. Annotations are provided for each label below the diagram.
The Browser, Mobile, and IoT Agents run in web/mobile/IoT applications, collecting metrics, and then transmitting that data to either a SaaS or an on-premises deployment of AppDynamics.
|The AppDynamics SaaS Cloud, consisting of the components listed below, stores, processes, and analyzes data, and then delivers RUM metrics to the Controller UI.|
The on-premises deployment of AppDynamics has most of the same components and data as the SaaS model. In this model, DevOps install and administer their own Controller Service, Events Service, and EUM Service. The EUM Synthetic Monitoring Service and session data, however, are not available in the on-premises deployment.
See the descriptions for each component above in step 2.
AppDynamics users can go to the AppDynamics Controller UI to view and analyze RUM metrics as snapshots, pages, Ajax requests, sessions, network requests, or in the form of charts and graphs.
See the description for the Controller UI in step 2.
Understand End User Activity
Using EUM, you can determine:
- Where in the world your heaviest application load is originated
- Where in the world 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 and IoT network requests are, and where the problem may lie
- How application server performance impacts the performance of your web and mobile traffic
- Whether your mobile or IoT applications are experiencing errors or crashes and the root cause of the issues. For example, for mobile applications, EUM provides stack traces and event trails for the crash or error, helping you troubleshoot and optimize mobile applications.
View EUM Data
The performance information generated by EUM is distinct from the application monitoring data generated by app server agents.
EUM data appears in various locations in the Controller UI, including in the User Experience dashboard, the Metric Browser, and, with the appropriate license, in AppDynamics Analytics pages.
When linked to application business transactions, EUM data gives you a complete view of your end users' experience from the client request, through the application environment, and back to the client as the user response.
You can view EUM performance data in the Controller UI in the User Experience tab. From there, you can access information specific to browser applications, mobile applications, or connected devices (IoT applications).
On-Premises EUM Deployments
By default, End User Monitoring is configured to use an AppDynamics-hosted component called the EUM Cloud. For a fully on-premises installation, the EUM Server provides the functionality of the EUM Cloud. For information, see EUM Server Deployment.
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:
If you are adding EUM to an existing on-premises Controller installation, you should evaluate your current configuration's ability to handle the additional load imposed by EUM. For more information, see Additional Sizing Considerations.
How EUM Works with other AppDynamics Products
This section describes how other App iQ Platform products work with End User Monitoring to provide complete, full visibility on application health and user experience.
EUM and Application Performance Management
Using Application Performance Management (APM) with EUM provides you with greater insight into how the performance of your business application affects the end user experience. To integrate APM with EUM, you correlate business transactions with browser snapshots. This enables you to trace bad user experiences to issues with your backend such as an unresponsive web service, bad database query, or slow server response. To learn how to integrate APM with EUM, see Correlate Business Transactions for Browser RUM.
You must assign unique names to EUM applications and business applications. For example, if you created the business application "E-Commerce", you cannot create a browser, mobile, or IoT application with that same name or vice versa.
EUM and Application Analytics
AppDynamics Application Analytics enables you to use the powerful AppDynamics Query Language (ADQL) to analyze different types of EUM data by through complex queries. The Analytics components are based on the Events Service, which is also the source of data for Browser Analyze, Crash Analyze, Network Requests Analyze, and all IoT data. Analytics requires a license separate from the EUM licenses except for IoT Monitoring.
