Instrumentation of the XMLHttpRequest object to collect AJAX timing data.

ImportantFor browser agent version 1220 and higher, usage of session cookies has been deprecated, so this information is only relevant if you're using browser agent version 1216 and lower. We use these methods to collect the page load timing information: Both API calls and the copy/paste method allow you to control when and where the script elements are inserted. The script elements can be injected automatically or via the agent API by an APM agent installed in the backend application, or they can be inserted manually via copy/paste. This additional script processes the collected data and reports it back to New Relic via so that you can see the data in your New Relic account. Once the page finishes loading, an additional script is downloaded from a CDN server. To collect data, browser monitoring uses JavaScript elements pasted or injected into your webpages, typically as part of the HEAD of the page, containing configuration details and essential browser environment instrumentation. Browser can also monitor apps with single-page application (SPA) architectures.

Additional monitoring after page load provides details on in-page AJAX calls, JavaScript errors, and other events and interactions.īrowser monitoring can leverage the New Relic agent to dynamically inject JavaScript into pages as they are built, in order to collect more detailed backend timing information. For standard page load timing, sometimes referred to as real user monitoring (RUM), we measure the overall time to load the entire webpage.
