Check your application health
The Dynatrace web UI offers a dedicated page where you can check the health of your web application.
To access the Application health check page
- In the Dynatrace menu, go to Web.
Select the application whose health you want to check.
- In the upper-right corner of the application overview page, select More (…) > Health check.
The following sections are available on the Application health check page:
In the RUM status section, you can see if RUM is activated for your application, related process groups, and hosts. Moreover, this section explains why Dynatrace doesn't capture RUM data for certain user sessions.
The following configuration-related RUM issues and warnings might be shown in this section:
|Issue or warning||Explanation|
RUM disabled for application
If RUM is disabled for your application, follow the provided link to enable RUM.
RUM disabled for process groups
If RUM is disabled for process groups related to your application, follow the provided links to configure these process groups.
RUM disabled for hosts
If RUM is disabled for hosts related to your application, follow the provided links to configure these hosts.
Not enough DEM units
If you've run out of DEM units, RUM is disabled and Dynatrace receives no data from your application.
Increase the DEM unit quota or enable DEM overages.
Opt-in mode enabled
When Data-collection and opt-in mode is enabled, Dynatrace doesn't capture any data until a special API method is called for specific user sessions.
If you want Dynatrace to capture data for all user sessions, disable this mode.
Do Not Track mode enabled
When the Comply with "Do Not Track" browser settings mode is enabled with the Turn Real User Monitoring off for "Do Not Track"-enabled browsers option, Dynatrace doesn't capture any data when a user has the "Do Not Track" setting turned on in their browser.
If you want to ignore the "Do Not Track" browser setting and capture RUM data from all browsers, disable the Do Not Track mode. Alternatively, you can select the Capture anonymous user sessions for "Do Not Track"-enabled browsers option to send anonymized data from such browsers.
When a diagnostics run is finished, the following information is available:
Number of injection attempts
List of target processes
Number and percentage of failed injections
Number and percentage of successful injections
Select Show more to view the injection failure reasons and the top five URLs for each issue.
