No RUM data after turning it on
Data appears about a minute after someone visits a page and leaves it or switches tab. Then check:
The page carries the script. Look for
/__waf/rum.jsin the HTML:curl -s https://www.example.com/ | grep -o '/__waf/rum.js[^"]*'The page qualifies. Only HTML pages answered with
200to aGETget the script. Excluded paths, pages without a</head>, and pages generated by the edge (challenges, block pages, access gate) don't.The sample rate. With
rum.sample_ratebelow1, only that share of page views is measured.The visitor is a real browser. Headless browsers and lab tools (Lighthouse, PageSpeed Insights, WebPageTest, Puppeteer, Playwright, Selenium…) are not measured.
The setting reached the edge. Check Changes › Propagation after turning RUM on, and that a per-name setting isn't turning it off for that name.
Pages are not measured because of the CSP
The report warns that your origin's Content-Security-Policy blocked the script on some page views. Allow 'self' in script-src and connect-src, or send a nonce in script-src (the edge reuses it). See Content-Security-Policy.
INP has no data
INP needs an interaction (tap, click or key press). Views without one have no INP; the assessment then uses LCP and CLS only.
Single-page app: every view is on the home page
A view is attributed to its landing page. Client-side navigations don't start new views, as in Chrome's field data. See Page views.
Traffic shows no data
Counters appear once your sites receive requests through the edge. Check that the names are proxied and, for an external zone, that they point at the edge. Days without traffic are left out of the API answer.
Security events say they aren't available
The dashboard shows Security analytics aren't available yet and the API answers 503 when the events store can't be reached. Protection keeps working and traffic counters are unaffected; try again later or contact [email protected] if it persists.
The live stream answers 429
An organization can hold up to 10 live event streams at once. Close other dashboard tabs in Live mode or other API clients.
