Performance analysis

The Performance analysis section displays a number of performance metrics for your application. Just expand the Performance analysis section of the infographic on the application overview page to view the performance analysis options.

Working with the infographic

Each area of the infographic appearing at the top is clickable, offering access to deeper detail regarding each metric. Whenever you click a part of the infographic, the left section right below the infographic shows different data that reflect the selected part.

The left-hand portion of the performance analysis infographic shows dimensional breakdowns of your application traffic based on browser type, user type, and geographic region. In the middle, you can see the different action types, the Apdex rating and the errors section, while on the right-hand side, the resources and the services sections are displayed. The top finding for each dimension is displayed by default in each section. The discrete infographic sections are briefly described below.

Application availability

If you have one or more synthetic monitors set up to test the availability of your application, you can see the availability of your application directly on the application overview page within the Availability section. The availability chart shows you an aggregate view of all of the selected application's synthetic monitors. You can click the View full details button to view details related to outages and navigate directly to synthetic monitor details (your analysis timeframe settings will remain intact) to perform further analysis.


Composite metrics across response times

This section helps you figure out from a high level perspective where your performance focus should lie. You can identify, for example, whether the duration up to the time to first byte is an issue for your application or you should focus on user perceived loading performance, indicated by Speed index and Visually complete.

If you click Analyze performance in the bottom right corner of this section, you can analyze your application’s performance and user actions across multiple dimensions.

Top 3 included domains

At a glance, you can see the Top 3 included domains, i.e. the domains that contain the largest number of actions that have been automatically detected by OneAgent in your environment. You can click View full details to view more details on the traffic coming from these domains and to define new applications.



The Problems section indicates problems that have been automatically detected by Davis, the Dynatrace AI engine. Just click on a problem to learn further details.


Top errors

The Top errors list displays the most frequently occurring errors by error type: JavaScript, HTTP, or Custom. You can configure errors by type or individually.

To view Top errors

  1. In the Dynatrace menu, go to Web.
  2. Select the application that you want to analyze and scroll down to Top errors.

Top 3 user actions

The Top 3 user actions list shows you the three slowest user actions. Actions are sorted based on priority (high priority actions are listed first) and total time consumed (duration multiplied by number of actions). The total time consumed measure is valuable because it factors in how frequently an action is called. For example, a slow action that is called often has more significant impact on performance than a slow action that isn't called often.

If you select a user action, you'll be directed to the user action overview page where you can further analyze the specific user action.

If you click View full details in the bottom right corner of the section, you can analyze your application’s performance and user actions across multiple dimensions.

user actions


Events represent system incidents that may be of interest to you. Such events include errors, new version deployments of your application, configuration changes, and more. The events shown in the image below were generated because the maximum number of user actions per minute was exceeded.
