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, deployment models (SaaS/on-premises), and the Controller UI as seen by AppDynamics end users. The SaaS deployment employs services (Controller Service, Events Service, EUM Service, EUM Synthetic Monitoring Service) to collect, store, and process data, whereas, the on-premises deployment requires customers to install discrete components such as the Controller and servers (Events Server, EUM Server) that run processes to collect, store, and process data.
Annotations are provided for each label below the diagram.
The Browser, Mobile, and IoT Agents run in web/mobile/IoT applications, collect metrics, and then transmit that data to either a SaaS or an on-premises deployment of AppDynamics.
|The AppDynamics SaaS Cloud, consisting of the components listed to the right, 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, Events Service, and EUM Server. The EUM Synthetic Monitoring Service and sessions data, however, are not available in the on-premises 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.
Using EUM, you can determine:
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).
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. 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, see:
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.
The SaaS EUM Server consists of the components listed below. Each component may have different endpoints depending on the region of your Controller.
If your SaaS or on-prem deployment requires access to any of these components on the Internet, make sure the URLs given in SaaS Domains and IP Ranges are accessible from your network.
For on-prem deployments, however, the EUM Server can either be located on the Internet or hosted inside your own data center/network. On-premises access points are configured at installation or through the UI. See EUM Server Deployment and Events Service Deployment for more information.
This section describes how other App iQ Platform products work with EUM to provide complete, full visibility on application health and user experience.
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 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.
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.
