Troubleshooting¶

How to Determine if the RUM SDK Initialization is Successful¶

1. Open the browser console:

1. Check whether the object DATAFLUX_RUM exists:

Exists:

Does not exist:

1. Execute DATAFLUX_RUM.getInternalContext() to check if the object has been initialized successfully:

If initialization is successful, you can retrieve information about objects such as the current application page's session, application, and view.

Initialization Failed¶

1. If you are integrating via CDN, ensure that your application is an https site;
2. Verify the configuration is correct (including the format and names of configuration parameters).

Initialization Succeeded, but Data Is Not Reported or Partially Reported¶

1. Check the browser version information and confirm that it supports the data according to the browser support list;
2. Check the initialization position of the RUM browser SDK and consider executing the initialization operation as early as possible in your application code.

XHR/FETCH Requests Are Not Associated with the APM Trace¶

Check if the allowedTracingOrigins configuration in the initialization settings is enabled and verify that the format is correct. (If using a regular expression, ensure that the array contains actual regular expressions, not strings)

Correct

datafluxRum.init({
    applicationId: '<DATAFLUX_APPLICATION_ID>',
    datakitOrigin: '<DATAKIT ORIGIN>',
    env: 'production',
    version: '1.0.0',
    trackInteractions: true,
    allowedTracingOrigins: [/https:\\/\\/.*\\.my-api-domain\\.com/] // Regular expressions should not be quoted
})

datafluxRum.init({
    applicationId: '<DATAFLUX_APPLICATION_ID>',
    datakitOrigin: '<DATAKIT ORIGIN>',
    env: 'production',
    version: '1.0.0',
    trackInteractions: true,
    allowedTracingOrigins: ["/https:\\/\\/.*\\.my-api-domain\\.com/"]
})

How to Confirm That APM and Frontend XHR/FETCH Are Successfully Linked¶

1. Open the browser console;
2. Confirm that the Request Headers of the XHR/FETCH requests contain the corresponding header keywords, as shown in the following image for ddtrace-related headers:
