Overview of End User Monitoring
Custom metrics for EUM Analytics are not supported in on-premises environments.
AppDynamics End User Monitoring (EUM) gives you visibility on the performance of your application from the viewpoint of the end user.
While Application Performance Monitoring (APM) 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, EUM 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 in the Splunk AppDynamics On-Premises deployment. This deployment requires you to install discrete components such as the Controller and servers (Events Server, EUM Server) that run processes to collect, store, and process data.
| Description | Component(s) | ||||||
|---|---|---|---|---|---|---|---|
The Browser, Mobile, and IoT Agents run in web/mobile/IoT applications, collect metrics, and then transmit that data to the Splunk AppDynamics On-Premises deployment. |
| ||||||
The Splunk AppDynamics On-Premises deployment requires the components that stores, processes, and analyzes data, and then delivers RUM metrics to the Controller UI. In this deployment, DevOps install and administer their own Controller, Events Service, and EUM Server. The EUM Synthetic Monitoring Service and sessions data, however, are not available in the on-premise deployment. |
| ||||||
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. | Controller UI |
Understand End User Activity
Using EUM, you can determine:
- Where geographically your heaviest application load is originated.
- Where geographically your slowest End User response times occur.
- How performance varies by
- location.
- client type, device, browser and browser version, and network connection for web requests.
- application and application version, operating system version, device, and carrier for mobile requests.
- What your slowest web/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, Metric Browser, and 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-Premise EUM Deployments
By default, EUM 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.
To host the Events Service on premises, see Install a Production EUM Server
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 Controller Sizing.
How EUM Works with other AppDynamics Products
This section describes how other App iQ Platform products work with EUM to provide complete, full visibility on application health and user experience.
EUM and Application Performance Monitoring
Using 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 backends 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 can also use the app server agents running on business applications that serve your browser applications to inject JavaScript agent into the code that runs on the browser. This obviates the need to manually inject the JavaScript agent. For more information, see Automatic Injection and Assisted Injection.
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 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.
