Data origin and collection
Web Analytics relies on the performance.getEntriesByType('navigation') object to collect metrics about page load performance. If Navigation Timing Level 2 is not supported, then performance.timing (Level 1) is used.
Refer to the W3C Processing Model for a visual depiction of the sequence of timing events for web page loads.
Data collection and reporting
Web Analytics collects the minimum amount of information - timing metrics - to show customers how their websites perform. Cloudflare does not track individual end users across our customers’ Internet properties.
The Web Analytics performance beacon loads from https://static.cloudflareinsights.com/beacon.min.js. You may need to update your Content Security Policy (CSP) settings to load this script.
Beacon data is sent to https://<yourdomainname>/cdn-cgi/rum for sites proxied through Cloudflare or https://cloudflareinsights.com/cdn-cgi/rum for sites not proxied through Cloudflare. Core Web Vital metrics are reported when the visibilityState is hidden for the first time after the page load event is triggered.
