Why am I not seeing Core Web Vitals data in the Synthetics - Browser Test Performance dashboard in Datadog?
After creating a synthetic browser test for a page that has Datadog's RUM javascript capturing data, I expected to see the Synthetic test web performance section of the Synthetics - Browser Test Performance dashboard display LCP and CLS data for the specified TestID. However, after letting the browser test run for a few days, I am not seeing anything.
Is there anything else that I need to enable or configure?
Update:
After seeing Keith's answer, I checked Collect RUM data for this test in the test recording page and now I'm seeing the data I was expecting.
The CLS and LCP widgets present on the Synthetics - Browser Test Performance dashboard do rely on RUM data.
Screenshot of the query: https://a.cl.ly/6quNQQbO RUM can be injected via the recording section of the browser test steps!
That being said, they can view CLS without leveraging RUM, using the synthetics.browser.step.cumulative_layout_shift metric.
