Browser data in distributed tracing

If you use New Relic Browser to monitor end-user browser activity, you can now see end-user-originating traces in New Relic's distributed tracing. This document contains:

Benefits of end-user spans in distributed tracing

By enabling New Relic to report browser monitoring data to distributed tracing, you can see the connection between front-end activity and back-end activity. You can see across a full transaction, from time spent by an end user in the web browser, to network activity, to associated back-end services.

Benefits of this feature:

  • Quickly spot latencies, errors, and anomalies in the browser or network
  • Resolve customer-facing problems more quickly
  • All the benefits of distributed tracing applied to your end-user monitoring

Requirements and compatibility

This feature reports same-origin (non-CORS) Fetch and XHR AJAX requests that occur during a browser interaction.

Find data

Tips for finding and querying data:

  • You can find end-user-originating traces in any New Relic One distributed tracing UI.
  • In the distributed trace UI, end-user spans are indicated with the New Relic distributed tracing browser span icon icon.
  • To see a span's attributes, select a span in the UI.
  • Spans are reported as Span data, and can be queried in New Relic.
  • Query tips:
    • Query by browser app name by setting to the browser app name.
    • Query for traces containing at least one browser app span with is not null.
    • Query for traces containing at least one back-end app with appName is not null.
    • Query for traces containing both browser and back-end spans by combining the two previous conditions.


If you don't see end-user spans, or are having other distributed tracing issues, see Troubleshooting.
